| Outline of Final Research Achievements |
The purpose of this study is to develop a method for fabricating non-metal clasp dentures by applying CAD / CAM. Non-metal clasp dentures are often used in clinical settings because they are aesthetically superior without using metal clasps. However, there are many problems, such as injection molding failure and requiring relatively short-term re-fabrication. The method of applying CAD / CAM would be a breakthrough in order to improve these problems. First, a disk for non-metal clasp denture production was made on a trial basis. Next, a denture was designed using CAD, and a denture base portion and an artificial tooth portion were produced using CAM. We developed such a digital workflow and completed a prototype denture.

本研究の目的は、CAD/CAMを応用してノンメタルクラスプデンチャーの作製方法を開発することである。ノンメタルクラスプデンチャーは金属クラスプを使用せず審美的な特徴を有するため、臨床で多用されている。しかし、射出成形がうまくいかないことや、比較的短期に再作製をすることが多い。これらを改善するにはCAD/CAMを応用する方法が考えられた。本研究でノンメタルクラスプデンチャー製作用のデジタルワークフローを開発し、プロトタイプの義歯を完成した。これによりノンメタルクラスプデンチャーの製作の簡便化や義歯紛失時の再製作などが容易になると考えられる。
