A new digital system, the Functionally Suitable Denture (FSD), simplifies complete denture fabrication. This innovative computer-aided design (CAD) and 3D printing approach reduces dental visits and improves accuracy for edentulous patients.
Area of Science:
- Dental prosthetics
- Digital dentistry
- Biomaterials engineering
Background:
- Conventional complete denture fabrication is time-consuming and involves multiple complex clinical steps.
- Existing methods have remained largely unchanged for nearly a century, leading to inefficiencies and potential errors.
- Edentulous patients often face challenges with traditional denture treatments, including lengthy procedures and variable outcomes.
Purpose of the Study:
- To develop a novel digital system, the Functionally Suitable Denture (FSD), to streamline complete denture restoration.
- To reduce the number of clinical steps, operational difficulties, and errors in denture fabrication.
- To enhance the accuracy, efficiency, and personalization of complete dentures through computer-aided design (CAD) and 3D printing.
Main Methods:
- Development of a digital workflow integrating a high-efficiency 3D scanner, specialized CAD software, and a dedicated 3D printer.
- Pioneering a computer-aided design (CAD) software utilizing template matching based on expert design principles.
- Implementing an innovative clinical operation process that combines functional impression, jaw relation recording, and try-in into a single step.
Main Results:
- The Functionally Suitable Denture (FSD) system successfully reduced the typical three steps (functional impression, jaw relation, try-in) to one, effectively halving the number of required dental visits.
- The developed CAD software enables efficient and intelligent design, facilitating the inheritance and iteration of expert knowledge.
- The system demonstrated novelty, creativity, and industrial utility, with all 15 patent claims validated by the Patent Cooperation Treaty (PCT).
Conclusions:
- The Functionally Suitable Denture (FSD) system offers a fast, simple, and accurate method for designing and manufacturing complete dentures.
- This digital approach overcomes the traditional limitations of being slow, difficult, and inaccurate, providing personalized functional and aesthetic outcomes.
- The FSD system presents a promising, potentially more accessible solution for edentulous patients, including those with severe alveolar ridge resorption or high occlusal forces.
