Introduction: Stepping into the Future of Dentistry, Today
The world of dentistry is in a constant state of evolution, with technological advancements continually reshaping how practitioners approach patient care, diagnostics, and treatment planning. Among the most transformative innovations of recent years is the integration of three-dimensional (3D) printing and design. What once seemed like a futuristic concept, confined to high-tech laboratories or specialized industrial applications, has now firmly established itself as an accessible and invaluable tool within the modern dental practice. For dentists aiming to stay at the forefront of their field, enhance clinical outcomes, and provide unparalleled patient experiences, understanding and mastering dental 3D printing is no longer a mere option but a compelling necessity. This technology is rapidly transitioning from a niche capability to a foundational element of comprehensive dental care, offering a spectrum of possibilities that were previously unimaginable.
What is Dental 3D Printing, Really?
At its core, dental 3D printing, a sophisticated form of additive manufacturing, involves the layer-by-layer construction of physical objects from digital designs. Imagine being able to transform a digital scan of a patient’s mouth into a tangible, highly accurate model, a custom-fitted surgical guide, or even a provisional restoration, all within your own practice. This is the reality that dental 3D printing brings. Unlike traditional subtractive manufacturing methods, which involve carving away material from a larger block, additive manufacturing builds objects from the ground up, using materials like specialized resins or polymers. This process not only minimizes waste but also allows for the creation of incredibly complex geometries and patient-specific devices with remarkable precision (Gibson, Rosen & Stucker, 2015). The growing adoption of this technology across dental practices globally underscores its proven benefits and its pivotal role in the ongoing digital transformation of dentistry. It’s a technology that empowers dentists with greater control, efficiency, and the ability to deliver truly personalized care.
The Shift from Traditional to Digital: A Quick Overview
The journey from traditional dental methodologies to a fully digital workflow has been accelerated significantly by the advent of 3D printing. For decades, dental professionals relied on manual impression techniques, often involving uncomfortable alginate materials, and outsourced laboratory work that could entail lengthy turnaround times and potential inaccuracies. While these methods have served dentistry for many years, the digital workflow, supercharged by intraoral scanners and 3D printers, presents a paradigm shift. Digital impressions captured with intraoral scanners provide a far more comfortable experience for patients and yield highly accurate 3D models almost instantaneously (Mangano et al., 2017). These digital files can then be seamlessly integrated with Computer-Aided Design (CAD) software, allowing dentists to design bespoke appliances or restorations, which are subsequently brought to life by an in-house 3D printer. The core benefits driving this shift are manifold: unparalleled precision in diagnostics and treatment, significant gains in operational efficiency by reducing chair time and lab turnarounds, and a vastly improved overall patient experience. This transition is not merely about adopting new gadgets; it’s about fundamentally enhancing the quality, speed, and personalization of dental care.

The Undeniable Importance: Why Learning 3D Printing is No Longer Optional for Dentists
The integration of 3D printing into dental practices represents more than just a technological upgrade; it signifies a fundamental shift in how dental care can be delivered, making it more precise, efficient, patient-centric, and economically viable. For dentists who are keen to not only keep pace with industry advancements but also to elevate their practice standards, embracing 3D printing and design skills is becoming increasingly crucial. The reasons are compelling and multifaceted, touching upon nearly every aspect of dental practice, from clinical outcomes to operational management and future readiness.
Enhancing Precision and Predictability in Treatments
One of the most significant advantages of incorporating 3D printing into dentistry is the unparalleled level of precision and predictability it brings to various treatments. Digital scans, converted into 3D printable files, allow for the creation of anatomical models, surgical guides, and dental appliances with an accuracy that is often difficult to achieve with traditional methods. For instance, 3D printed surgical guides, designed from a patient’s CBCT scan and intraoral scan data, enable implant placement with remarkable accuracy, minimizing risks and improving the predictability of surgical outcomes. Studies have indicated that such guides can significantly reduce implant placement errors when compared to freehand techniques (D’haese et al., 2012). This enhanced precision extends to the fabrication of restorations, orthodontic models, and various other dental devices, ensuring a better fit and, consequently, more successful and durable clinical results. The ability to work with highly accurate, patient-specific digital models reduces the guesswork and variability often associated with manual techniques, leading to more consistent and reliable treatment outcomes.
Transforming the Patient Experience
Beyond the clinical benefits for the practitioner, 3D printing profoundly transforms the patient experience, making dental visits more comfortable, convenient, and engaging. The most immediate impact is often felt during the impression-taking process. Traditional impressions, with their bulky trays and often unpleasant-tasting materials, can be a source of anxiety and discomfort for many patients, particularly those with a sensitive gag reflex. Intraoral scanners, the gateway to 3D printing, eliminate this ordeal, replacing it with a quick, non-invasive digital scan (Gallardo et al., 2018). Furthermore, 3D printing can significantly reduce the number of appointments required for certain treatments and enable the provision of same-day restorations in some cases, such as provisional crowns or bridges. Patients also benefit from appliances that are custom-designed and printed for a perfect fit, enhancing comfort and efficacy. The ability to show patients 3D printed models of their dentition or proposed treatment plans also improves communication and understanding, fostering greater patient involvement and acceptance of treatment.
Cost-Effectiveness and Boosting Practice Growth
While the initial investment in 3D printing equipment and software might seem substantial, the long-term economic benefits can be considerable, contributing to both cost-effectiveness and practice growth. By bringing the production of models, surgical guides, aligners, night guards, and even some provisional restorations in-house, dentists can significantly reduce their reliance on external dental laboratories and the associated fees. This not only cuts down on operational expenses but also provides greater control over the production timeline and quality. Many dental practices that have adopted in-house 3D printing report a return on investment within a relatively short period, often cited as 6 to 18 months, with substantial savings on laboratory costs for specific applications (reported in user-provided text, similar sentiments echoed by Freedman, as cited in Listek, 2025). These savings can be reinvested into the practice or potentially passed on to patients, making treatments more accessible. Moreover, offering advanced, digitally driven services can differentiate a practice, attract new patients, and ultimately fuel its growth in an increasingly competitive market.
Expanding Your Clinical Capabilities and Service Offerings
Mastering 3D printing and design empowers dentists to broaden their range of clinical services and tackle more complex cases with greater confidence. The technology opens doors to producing a wide array of custom dental devices in-office. These include, but are not limited to, highly accurate surgical guides for implant placement, models for diagnostic wax-ups and digital smile design presentations, custom impression trays, clear aligners for orthodontic treatment, occlusal splints and night guards for bruxism, provisional crowns and bridges, and even components for dentures. The ability to create detailed educational models from patient scans can also be invaluable for patient communication and case presentation. This expansion of in-house capabilities not only enhances the scope of treatments offered but also allows for a more agile and responsive approach to patient needs, as custom solutions can be designed and fabricated more rapidly.
Future-Proofing Your Dental Practice
Dentistry is on an undeniable trajectory towards increasingly digital workflows, and 3D printing is a cornerstone of this evolution. By embracing these technologies now, dentists are not just adopting a new tool but are strategically positioning their practices for the future. The global dental 3D printing market is experiencing significant growth, with projections indicating a substantial increase in market value in the coming years (Listek, 2025, referencing market growth). This trend highlights the accelerating adoption and the integral role that 3D printing will play in the dental practices of tomorrow. Early adoption allows practitioners to build expertise, refine their digital workflows, and stay ahead of the curve, ensuring they remain competitive and are well-equipped to meet the evolving expectations of patients and the advancements within the dental industry. Delaying the integration of such foundational digital technologies may mean playing catch-up later in a landscape where digital proficiency becomes the standard of care.

Diving Deeper: Understanding the Core Technologies and Materials
As dentists venture into the realm of 3D printing, a foundational understanding of the core technologies and materials involved is paramount. This knowledge not only aids in selecting the right equipment and consumables for specific clinical needs but also ensures the safe and effective application of these powerful tools. The landscape of dental 3D printing is diverse, with various technologies offering distinct advantages, and a growing array of specialized materials designed to meet the stringent requirements of dental applications, particularly concerning biocompatibility and mechanical performance.
Key 3D Printing Technologies for Dental Applications
Several 3D printing technologies have found significant application in dentistry, each with its unique mechanism, strengths, and ideal use cases. The choice of technology often depends on the desired level of accuracy, speed, material compatibility, and the specific dental items being produced.
The Critical Role of Resins and Biocompatible Materials
The materials used in dental 3D printing, particularly for resin-based technologies like SLA and DLP, are as critical as the printers themselves. Dental resins are specially formulated photopolymers designed to meet the specific demands of oral applications, including mechanical strength, aesthetic appearance, and, most importantly, biocompatibility.
Curing and Post-Processing: Ensuring Safety and Efficacy
The 3D printing process for resin-based parts does not end when the printer stops. Proper post-processing, particularly washing and post-curing, is essential to achieve the desired mechanical properties and, critically, to ensure the biocompatibility of the final dental appliance. Neglecting these steps can have serious consequences.
Understanding these technological and material aspects empowers dentists to make informed decisions, optimize their 3D printing workflows, and ultimately provide safe, effective, and high-quality care to their patients.

The Workflow: Your Step-by-Step Guide to Integrating 3D Printing
Transitioning to a 3D printing workflow in a dental practice involves a series of interconnected steps, transforming a patient’s clinical situation into a tangible, custom-made dental appliance or model. This digital pathway, from initial data acquisition to the final printed object, is designed to enhance accuracy, efficiency, and patient outcomes. Understanding this workflow is fundamental for any dentist looking to successfully integrate 3D printing technology. It typically begins with capturing the patient’s anatomy digitally and culminates in a precisely fabricated, patient-specific item.
Step 1: Embracing the Digital Impression – The Power of Intraoral Scanners
The gateway to most dental 3D printing applications is the acquisition of precise digital data representing the patient’s oral anatomy, and this is predominantly achieved through the use of intraoral scanners (IOS). These handheld devices have revolutionized the traditional impression-taking process. Instead of using physical impression materials, an IOS uses advanced optical technology, often structured light or confocal microscopy, to capture thousands of images per second, which are then stitched together by sophisticated software to create a three-dimensional virtual model of the teeth and surrounding soft tissues (Richert et al., 2017). The benefits of intraoral scanners are numerous: they offer significantly improved patient comfort by eliminating the need for bulky trays and gag-inducing materials; they provide exceptional accuracy, often surpassing that of conventional impressions when performed correctly; scans can be visualized in real-time, allowing for immediate verification and correction if needed; and they eliminate the material inaccuracies and dimensional changes associated with traditional impression materials and stone model pouring. Furthermore, the digital files generated by IOS (commonly in formats like STL, PLY, or OBJ) are easily stored, retrieved, and transmitted electronically to a dental lab or directly to the in-house design and printing setup, forming the crucial foundation for the entire analog to digital dental workflow (Mangano et al., 2017). Learning how important intraoral scanners are for 3D printing in dentistry is the first crucial realization for any practice considering this technological leap.
Step 2: CAD Software – Designing for Dental Excellence
Once the digital impression is captured, the next phase involves using Computer-Aided Design (CAD) software. This specialized software allows the dentist or a trained technician to manipulate the 3D scanned data and design the desired dental appliance, restoration, or model with high precision. Dental CAD software often comes with libraries of tooth anatomies, tools for defining margins, designing contours, and creating various structures. Dentists can design a wide array of items, including crowns, bridges, veneers, inlays, onlays, surgical guides, orthodontic aligners, occlusal splints, and custom implant abutments (Van Noort, 2012). While some dental CAD software is proprietary and may be linked to specific scanner or printer ecosystems, there is also a growing interest in what open source software can be used in dentistry 3D printing and design. For instance, versatile open-source programs like Blender, with its robust mesh editing capabilities, or FreeCAD, a parametric modeler, can be adapted for certain dental design tasks, particularly for users with some technical inclination. Meshmixer, while technically freeware, is also widely used for processing scan data, hollowing models (to save printing material), and generating support structures. The learning curve for dental CAD software can vary depending on its complexity and the user’s prior experience, but numerous training resources, including manufacturer-led courses, online tutorials, and workshops, are available to help dental professionals become proficient.
Step 3: Slicing Software – Preparing Your Design for Print
After the design is finalized in the CAD software, it must be prepared for the 3D printer. This is where slicing software comes into play. The primary function of a slicer is to take the 3D model (usually an STL or OBJ file) and digitally cut it into hundreds or thousands of thin horizontal layers. It then generates the specific machine code (often G-code) that instructs the 3D printer on how to build each of these layers sequentially (Chua, Leong & Lim, 2010). Slicing software also allows the user to define critical print parameters, such as layer height (which affects print speed and resolution), exposure time per layer (for resin printers), infill density (for FDM printers), and print speed. Crucially, for many 3D printing technologies, especially SLA and DLP, the slicer is also used to generate support structures. These are temporary scaffold-like additions that ensure overhanging parts of the design are printed correctly and prevent deformation during the printing process. Popular open-source slicers like Cura (primarily for FDM but adaptable) or PrusaSlicer (which also has good resin support capabilities) are often used, though many dental 3D printer manufacturers provide their own proprietary, optimized slicing software tailored to their machines and materials. Careful attention to slicing parameters is vital for achieving successful prints with the desired accuracy and material properties.
Step 4: The Printing Process – Bringing Digital Designs to Life
With the sliced file ready, the actual 3D printing process can begin. This involves setting up the 3D printer, which includes ensuring the build platform is clean and calibrated, loading the chosen material (e.g., pouring resin into the vat for SLA/DLP printers, or loading a filament spool for FDM printers), and transferring the sliced file to the printer, usually via USB, Wi-Fi, or Ethernet. Once the print job is initiated, the printer will meticulously build the object layer by layer according to the instructions from the sliced file. While many modern dental 3D printers are designed for ease of use and automated operation, it is often advisable to monitor the initial layers of the print to ensure proper adhesion to the build plate and to check for any immediate signs of print failure. The duration of the printing process can vary significantly depending on the size and complexity of the object, the chosen layer height, and the specific printing technology being used, ranging from under an hour for small items to several hours for larger or multiple parts.
Step 5: Post-Processing – The Crucial Finishing Touches
The journey from digital file to usable dental part doesn’t conclude when the 3D printer finishes its job. Post-processing is a critical stage, especially for resin-based prints, to ensure the parts are clean, fully cured, mechanically sound, and biocompatible. For resin prints (SLA/DLP), the typical post-processing steps include:
- Washing: The printed part, once removed from the build platform, will be covered in uncured liquid resin. This excess resin must be thoroughly washed off, typically using a solvent like isopropyl alcohol (IPA) in a dedicated wash station or ultrasonic cleaner. This step is crucial to remove any residual monomer that could otherwise cause irritation or affect the part’s final properties (Unkovskiy et al., 2018).
- Drying: After washing, the part must be completely dried before post-curing.
- Post-Curing: As discussed earlier, post-curing involves exposing the washed and dried part to UV light of a specific wavelength and often controlled temperature for a designated period. This step is vital to complete the polymerization process, achieving the material’s final mechanical strength, stability, and, most importantly, its biocompatibility. Skipping or improperly performing this step can render a dental appliance unsafe for intraoral use.
- Support Removal: The support structures generated by the slicing software, which helped to stabilize the part during printing, must now be carefully removed. This can be done using clippers, scalpels, or specialized tools, followed by light sanding or polishing if a very smooth surface is required.
For FDM prints, post-processing is generally simpler, often involving just support removal (if supports were used) and potentially some surface finishing like sanding or smoothing if aesthetics are important. Regardless of the technology, meticulous post-processing is key to realizing the full potential of 3D printed dental applications.

Logical Steps to Learn the Workflow: Your Roadmap to 3D Printing Proficiency
Adopting 3D printing technology into a dental practice is an exciting prospect, but like any significant technological integration, it requires a structured approach to learning and implementation. For dentists wondering about the logical steps to learn the 3D printing workflow, the journey to proficiency can be broken down into manageable stages. It’s not just about acquiring the hardware; it’s about developing the skills and understanding to leverage it effectively for improved patient care and practice efficiency. This roadmap will guide you through the essential phases of becoming adept at dental 3D printing.
Start with Education: Courses, Workshops, and Online Resources
The foundational step in mastering any new dental technology is comprehensive education. Before even considering equipment purchases, invest time in understanding the principles of dental 3D printing, the various technologies available (SLA, DLP, FDM), material science (especially biocompatibility and resin properties), and the complete digital workflow from scan to final product. There is a wealth of resources available for learning dental 3D printing. Many dental continuing education (CE) programs now offer specialized courses and hands-on workshops focused on digital dentistry and 3D printing (Scherer, 2021). These structured learning environments provide both theoretical knowledge and practical experience. Additionally, equipment manufacturers often provide training sessions specific to their systems. Beyond formal courses, the internet is rich with information; online forums, professional groups on social media, webinars, and video tutorials from experienced users and key opinion leaders can offer invaluable insights, tips, and troubleshooting advice. Actively seeking out these educational opportunities will build a strong theoretical and practical base.
Begin with Simpler Applications
Once you have a foundational understanding, it’s wise to start your practical journey with simpler, less clinically critical applications. This allows you to familiarize yourself with the equipment, software, materials, and workflow without the immediate pressure of producing complex, patient-facing devices. Excellent starting points often include 3D printing dental models from intraoral scans. These are relatively straightforward to design (or often require minimal design input if simply printing a scanned model) and print, yet they provide immense value for diagnostics, treatment planning, and patient communication. Another common entry-level application is the fabrication of custom impression trays or simple surgical guides for non-complex cases (once design proficiency is achieved). As you gain confidence and experience with these beginner dental 3D printing projects, you can gradually progress to more intricate applications like occlusal splints, provisional restorations, or components for clear aligner therapy. This phased approach helps in building skills incrementally and managing the learning curve effectively.
Invest Wisely in Equipment and Software
Choosing the right equipment is a critical decision. Your research during the educational phase should inform your selection of a dental 3D printer. Consider factors such as the types of applications you intend to focus on (e.g., SLA or DLP printers are generally preferred for high-precision applications like surgical guides and restorations, while FDM might suffice for basic models), the printer’s accuracy, build volume, speed, ease of use, and the range of compatible materials, especially biocompatible resins certified for dental use. It’s not always about buying the most expensive system; it’s about selecting one that meets your current and anticipated future needs and budget. Equally important is the choice of software. Ensure the CAD software you select is intuitive enough for your skill level yet powerful enough for your desired applications. Consider compatibility between your intraoral scanner, CAD software, and 3D printer to ensure a seamless workflow. Some manufacturers offer integrated ecosystems, which can simplify the initial setup, while open systems offer more flexibility. Don’t forget to factor in the costs of consumables (resins, cleaning agents), post-processing equipment (wash and cure stations), and ongoing maintenance when budgeting for your dental 3D printing setup.
Practice, Iterate, and Seek Mentorship
There is no substitute for hands-on experience in mastering dental 3D printing. Dedicate time to practice regularly, working through the entire workflow from scan to finished part. Expect a learning curve; not every print will be perfect initially. Treat failed prints not as setbacks but as learning opportunities. Analyze what went wrong – was it the design, orientation, support structures, slicing parameters, or material handling? Keep detailed notes of your print settings and outcomes to refine your techniques over time. Iteration is key. Furthermore, connecting with experienced colleagues who have already integrated 3D printing into their practices can be incredibly beneficial. Seeking mentorship, whether formally or informally, can provide practical advice, help you avoid common pitfalls, and accelerate your learning process. Joining study clubs or user groups focused on digital dentistry can also provide a supportive community for sharing knowledge and experiences. The journey to proficiency is ongoing, as materials and technologies continue to evolve, requiring a commitment to continuous learning and adaptation.
By following these logical steps, dentists can systematically build the knowledge and skills required to confidently and effectively integrate 3D printing and design into their daily practice, ultimately enhancing the quality of care they provide.

Frequently Asked Questions (FAQs)
Q: What exactly is dental 3D printing used for in a typical practice?
A: Dental 3D printing has a surprisingly wide range of applications. Some of the most common uses include creating highly accurate dental models for diagnostics, treatment planning, and patient education. It’s extensively used for fabricating surgical guides for precise implant placement, which significantly improves predictability and safety. Dentists also use it to produce custom impression trays, orthodontic appliances like clear aligners (or models for their fabrication) and retainers, occlusal splints and night guards for bruxism, and provisional (temporary) crowns and bridges. Some advanced systems and materials even allow for the printing of components for dentures and, increasingly, more definitive restorations.
Q: How does 3D printing improve upon traditional dental methods?
A: 3D printing offers several key advantages. Precision is a major one; digital designs lead to highly accurate physical objects, reducing errors and improving the fit of appliances. Efficiency is another; in-house printing can drastically cut down turnaround times compared to sending work to external labs, enabling same-day dentistry for some procedures. It enhances the patient experience by eliminating uncomfortable traditional impressions (thanks to intraoral scanners) and often reducing the number of appointments. Furthermore, it can be cost-effective in the long run by reducing lab fees and material waste. Finally, it allows for greater customization and the ability to create complex geometries that are difficult or impossible with traditional techniques.
Q: Is learning to use a dental 3D printer and design software difficult for a dentist?
A: There is a learning curve, as with any new technology. However, modern dental 3D printers and accompanying software are becoming increasingly user-friendly. The complexity depends on the specific system and the types of applications you intend to use. Basic model printing from a scan might be relatively straightforward, while designing complex restorations or surgical guides requires more dedicated training. Many manufacturers offer comprehensive training, and numerous third-party courses, workshops (like the ones mentioned earlier in this post!), and online resources are available. Starting with simpler applications and gradually progressing is a good strategy.
Q: What are the main types of 3D printing technologies used in dentistry?
A: The most common resin-based technologies are SLA (Stereolithography) and DLP (Digital Light Processing). Both use UV light to cure liquid resin layer by layer and are known for high accuracy and fine detail, making them ideal for surgical guides, models, and aligners. FDM (Fused Deposition Modeling) is another technology that extrudes thermoplastic filament; it’s generally more affordable but offers lower resolution, making it suitable for study models or custom trays where ultra-high precision isn’t the primary concern.
Q: What kind of materials are used, and are they safe for patients?
A: A variety of specialized dental resins are used, primarily with SLA and DLP printers. These resins are formulated for specific applications and, crucially, for biocompatibility. Materials intended for intraoral use (e.g., surgical guides, splints, temporary crowns) must be certified as biocompatible by regulatory bodies (like the FDA) and meet specific ISO standards. These are often classified (e.g., Class I, Class IIa) based on their intended use and duration of contact with the body. It is essential to use the correct, certified material for each application and to follow all manufacturer instructions for printing and post-processing (especially curing) to ensure patient safety.
Q: How much does it cost to set up 3D printing in a dental office?
A: The initial investment can vary widely, from a few thousand dollars for entry-level FDM or simpler resin printers to tens of thousands for high-end, high-throughput systems with advanced capabilities and software. You also need to factor in the cost of an intraoral scanner (if you don’t already have one), CAD software (some is open source or bundled, others have subscription fees), a wash station, a curing unit, and ongoing consumable costs for resins and other materials. While the upfront cost is a consideration, many practices find that the savings on lab bills and increased efficiency lead to a good return on investment over time.
Q: Can I 3D print permanent crowns or dentures in my office?
A: The ability to print truly permanent, long-lasting restorations like crowns and full dentures in-office is an area of rapid development. While many systems can print highly aesthetic and durable provisional (temporary) crowns and bridges, and components for dentures (like bases or try-ins), the materials and technology for directly 3D printing final, permanent ceramic-like restorations are still evolving and becoming more mainstream. Some newer, advanced resins are gaining clearance for longer-term use, but it’s crucial to use materials specifically approved for such applications and to understand their longevity and clinical performance data.
Q: What are the key steps in the dental 3D printing workflow?
A: The typical workflow involves:
- Scanning: Acquiring a digital impression using an intraoral scanner.
- Designing: Using CAD software to design the desired appliance or model from the scan data.
- Slicing: Preparing the digital design for printing using slicing software, which converts it into printable layers and adds supports.
- Printing: Sending the file to the 3D printer and fabricating the object layer by layer.
- Post-Processing: Washing the printed part (to remove excess resin), post-curing it with UV light (to achieve full strength and biocompatibility), and removing support structures.
Q: What open source software options are available for dental 3D printing?
A: While many dental-specific CAD programs are proprietary, some dentists explore open-source options. Blender is a powerful, free 3D creation suite that can be used for mesh editing and some design tasks. FreeCAD is an open-source parametric modeler. Meshmixer (freeware from Autodesk) is very popular for processing scan data, hollowing models, and creating supports. For slicing, Cura and PrusaSlicer are popular open-source options that can be configured for various printers, including some resin printers. However, using open-source software may require more technical expertise and a steeper learning curve for dental-specific applications compared to dedicated dental software.
Q: How do I ensure the 3D printed dental appliances are safe and biocompatible?
A: This is paramount. Always use dental resins specifically designed and certified as biocompatible for the intended intraoral application (e.g., Class I for surgical guides, Class IIa for splints or temporary crowns). Strictly follow the manufacturer’s instructions for use (IFU) for printing parameters, washing procedures (correct solvent, duration), and, most importantly, thorough post-curing using the recommended UV curing unit, wavelength, and time. Incomplete curing is a major cause of leachable monomers and potential adverse reactions. Maintain good records of materials and processes used. Also, ensure proper handling with PPE during the process.
