摘要/Abstract

摘要：

全程可控最少的牙体预备量对于获得长期稳定有效的微创美学修复至关重要,这也是美学修复的一大难点。在成熟的定深孔引导技术基础上,通过数字技术可以更高效更准确地实施牙体预备。本技术在实际临床牙体预备前,先在计算机上进行未来修复体虚拟轮廓和分层、虚拟咬合等设计,再根据修复体的设计进行虚拟的回切式牙体预备,根据虚拟的预备体轮廓形态,结合术前基牙轮廓,设计虚拟钻孔手术方案,制作并3D打印牙体预备导板。这种方法实现了牙体预备的全程量化、精准引导、修复空间可视化,减少了临床操作时间,保证了备牙质量;对数字化实操教学质量的提升也有很好的推动。

Abstract:

The minimum amount of tooth preparation that can be fully controlled is crucial in achieving long-term, stable, and effective aesthetic restoration, which is also a major difficulty in aesthetic restoration. The tooth preparation can be implemented efficiently and accurately through digital technology based on the fixed-deep hole guiding technology. Prior the actual tooth preparation, the technology first designs the virtual contour, layering, and virtual occlusion of the prosthesis on the computer. Then, virtual tooth preparation is carried out by cutting back according to the virtual prosthesis. Next, the virtual drilling operation plan is designed according to the shape of the virtual tooth preparation and the contour of the abutment tooth. Finally, the tooth preparation guide plate is designed and printed in 3D. It realizes the whole process of quantitative and precise guidance of dental preparation, visualizes the restoration space, reduces the clinical operation time, and guarantees the quality of dental preparation. It also promotes the improvement of the teaching quality of digital practical exercises.

Key words: digital design, precise tooth preparation, tooth preparation guide, 3D printing
