3D Printed Dentures: Places to Get Ideas
Before you start questioning it, 3D Printing in dentistry is real and probably used by many people you know. Dentures are going to be in people's mouths, so it is important to use materials that do not harm the health of the user. Metals and their amalgams have been used to make dental implants or to plate teeth, but metals can cause multiple issues. Firstly, there is the problem of biocompatibility; metals are reactive, which means that metals can react with fluids in the mouth and get corroded; the by-products of corrosion could cause harm by interacting with bodily functions. Another aspect of biocompatibility is that metals could be toxic or cause allergies. Secondly, metals are prone to cracks and breakage as they are more rigid than normal teeth, also, metals can expand or contract due to temperature changes.
3D Printing uses special polymers that address all these issues. Acrylate-based resins such as PMMA are used to make the structure; these are durable and biocompatible. They are also effortless to print. Polyethylene is used to make bases that offer a comfortable fit. If polyurethane is used to make the bases, it makes them stronger and more durable. Other materials like Nylon, PEEK, and TPU are also used to make components that make high-quality dentures. Apart from functional dentures, which require the expertise of a dentist, enthusiasts can use 3D printing to create models for educational purposes, recreation, or cosplaying.
What Are the Best Options to Get Inspiration for 3D Printing Dentures?
1. 3D Models in Repositories
This is the fastest and easiest way to find inspiration for 3D Printing Dentures. 3D Models of dentures can be found in online repositories. Some repositories, such as Thingiverse, Cults3D, and Sketchfab, are great places to find models. Here are some examples:
1. Upper and Lower Dentures
This is an STL model of the upper and lower sets of teeth. You can 3D print this model to use as an amazing tool for teaching and learning purposes. You can buy this model from Cults3D at $5.30.
2. D-Mold
This one makes it easy for you to create dentures to display the anatomy of teeth. This works as a mold for you to build models. This intricately detailed model is perfect for developing teaching and learning tools. You can download this model for free from Sketchfab.
3. Full Maxillary Dentures With Separate Files for Teeth
This model is optimized for 3D Printing. This package also comes with separate files for the teeth to enable you to print the teeth using materials that resemble natural teeth and the gums separately using other materials. The creator has specified that this model was designed as an educational tool. You can download this model from Thingiverse.
4. T-Rex Dinosaur Dentures
This is purely for recreational purposes. This is modeled after a T-Rex Jaw. This model comes with a strip joining the upper and lower dentures. Heating this strip helps you bend it and position the upper teeth over the lower teeth. This model was built for 3D printing. You can download it from Thingiverse.
5. Dental Guide
If you are a dental surgery student, you know or will eventually realize the importance of a dental guide. Dental guides are crucial tools in maxillofacial surgery and dental implantology/ Dental surgeons and prosthodontists create a 3D structure of the patient’s mouth, made through scans and measurements. This guide is then used to try out the best approach to the surgery, which implant to use, and the best angle or method to install it. This model is an example of a dental guide. This can be used as a tool for teaching dental students. You can download this model on Thingiverse.
6. Full Denture for 3D Printing, Injection Molding, and Milling
We like multipurpose objects. This full-set denture model has been designed to be manufactured in three different ways. You can 3D Print the STL file, Mill the shape using a block of the desired material, or create a mold for injection molding. You can download the files from Cults3D.
7. 3D Scan of Dentures
This model on Sketchfab results from 3D scanning using a Thunk3D dental scanner. This would work great as an educational model. This incredible model is available for free download. You can download it here.
2. Professional Journals and Publications
The second place you can look for inspiration is in journals and publications related to dentistry. In such journals and periodicals, you will find articles covering recent developments in modern technology, such as 3D printing, to create dental applications such as Dentures. These articles will have detailed descriptions of the materials and the steps involved. Or you will find citations that will lead you to other publications containing the instructions or information you require. Some examples of such Journals are “The Journal of Dentistry,” “Oral and Maxillofacial Surgery Cases,” and “Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology”. The advantage of referring to such publications is that the authors mention any gaps in the research or shortcomings. You can use this information to develop ways to overcome these gaps when your model is 3D printed.
3. Attending Conferences And Seminars
Communities related to dentistry conduct conferences and seminars to keep themselves updated and to discuss ways to solve common issues related to surgery or implants. Such forums would involve discussions of case studies, innovative approaches such as 3D Printed Dentures, and inputs from experienced minds. Sometimes, workshops that help you learn more about dental sciences and dentures would also be conducted as part of such seminars and conferences. Such conferences and seminars are also great opportunities for networking. You will meet experts and gain access to new ways of thinking; you will meet peers who might have found solutions to the problems you are facing; you will meet peers who could use your help; and you will meet manufacturers of printing materials that can help make your prints more functional.
4. Training Programs
Most often, dentists are not directly involved in manufacturing dentures; they only work behind the scenes in planning the surgery or the type of dentures or implants needed. For this reason, institutions or dental schools offer special courses for manufacturing dentures to outsiders. You can use these programs to understand the ins and outs of manufacturing dentures. With the advent of additive manufacturing of dentures, such courses also provide insights into using modern technology to manufacture dentures. You will be introduced to ways to understand how dimensions work, what kind of materials to use, what printing technology to use, and the ideal print settings.
5. Dental Technology Exhibitions
Dental Technology Exhibitions open your network to new technology, equipment, printing material, and new approaches to creating dentures and implants through technologies like additive manufacturing. Manufacturers use such expos to exhibit the capabilities and technologies of their machines. You can observe these technologies, return to your drawing board, and get inspired to design 3D Printable dentures with better functionality and comfort. The first person to 3D print dentures thought differently by avoiding amalgams of metals due to their adverse effects. Perhaps you can go to one of these exhibitions and discover materials that offer better biocompatibility, comfort, and durability.
6. Following Research Institutions
Research institutions that focus on using 3D printing for manufacturing Dentures always work on finding new innovative techniques to 3D print dentures. They often publish their findings through different platforms; following these organizations will keep you updated about potential innovations in 3D printing dentures and help you improve your thought process and develop new ideas.
7. Online Dental CAD Software
Software such as exocad and 3Shape has an online component that involves a platform or a community where other users can share their designs, queries, and fixes to common issues. You can take inspiration from such posts or help other users solve their problems, broadening your perspective and getting better ideas.
Which is the Best CAD Software for Dentistry
Creating 3D models of dentures is not a simple task; dentures are meant to improve people's lives, so utmost care has to be taken while designing or modifying the 3D scans. Choosing a proper 3D CAD software is a crucial part. Your software should have a tool suite with powerful tools capable of making designs that match the exact requirements put forward by the recipient; simultaneously, the tools must be intuitive and easy to use. The software also should be affordable enough for those on budget to afford. The software should also come with learning materials for one to get started easily.
