PURPOSE
To investigate a computer-aided design/computer-aided manufacturing (CAD/CAM) process for producing one-piece removable partial dentures (RPDs) and to evaluate their fits in vitro.
MATERIALS AND METHODS
A total of 15 one-piece RPDs were designed using dental CAD and reverse engineering software and then fabricated with polyetheretherketone (PEEK) using CAM. The gaps between RPDs and casts were measured and compared with traditional cast framework RPDs.
RESULTS
Gaps were lower for one-piece PEEK RPDs compared to traditional RPDs.
CONCLUSION
One-piece RPDs can be manufactured by CAD/CAM, and their fits were better than those of traditional RPDs.
目的
研究一种用于制作一体式可摘局部义齿（RPD）的计算机辅助设计/计算机辅助制造（CAD/CAM）工艺，并在体外评估其贴合度。
材料与方法
使用牙科CAD和逆向工程软件设计了总共15个一体式RPD，然后使用CAM用聚醚醚酮（PEEK）制作。测量RPD与模型之间的间隙，并与传统铸造支架RPD进行比较。
结果
与传统RPD相比，一体式PEEK RPD的间隙更小。
结论
一体式RPD可通过CAD/CAM制造，其贴合度优于传统RPD。
