Our Approach
Case Study: Digital Dentures
The applications for 3D printing are constantly widening, with machine makers continuously improving the achievable part quality, finish and availability of their materials. The use of additive manufacturing in the dental sector was previously unfeasible for the majority of clinics and labs; however, a recent convergence of such technologies as well as the introduction of biocompatible materials now makes 3D printing a real alternative to traditional methods.
ITERATE collaborated with a local denture lab to explore how intraoral scanning, additive manufacturing and digital file sharing could benefit denture production. The laboratory provided a partial denture that had been crafted using traditional methods. The technical challenge was to create a product of similar quality within a quicker time-frame by optimising the workflow through leveraging these technologies.
In order to achieve this, we identified suitable CAD software and tooth libraries that would allow us to develop efficient and repeatable production techniques including: the scanning process; CAD production; print settings; and finishing methods. Once established, we produced several development prototypes using mutiple 3D printing technologies. This allowed us to further optimise the production process before producing final models in denture and tooth coloured biocompatible resins, which we had identified as being realistic and suitable for dental use.
The final outcome consisted of a highly flexible and repeatable digital workflow, and a realistic denture model approved as being equal quality to traditional alternatives. This case study has since gained interest from several local dentists and dental laboratories, who have expressed an interest in other dental products that can be produced in this way.
Success Factors
Having developed a series of custom fit dental products for denture clinics, labs and practices, the following benefits have been observed:
- 1. Faster turnaround time due to speed of scanning and printing technologies
- 2. Increased product accuracy due to fewer steps in the production process and achievable tolerance of 3D printing
- 3. Enhanced patient experience; less chair time required in the dental clinic
- 4. Potential 80% material saving compared to traditional methods offering sustainability benefits
- 5. Higher levels of patient comfort and reduced rejection rates due to precision fit.
