牙种植中动静态系统的精度分析

Analysis of Accuracy between Static and Dynamic System in Dental Implantation

计算机辅助种植外科发展迅速,但在快速运用于口腔种植的同时也暴露出手术误差方面的问题,而针对误差的解决方案也在不断更新。引导性导板技术与无翻瓣技术结合,辅助微螺钉的应用,能够给予完全无牙颌患者更好的手术效果。动态导航在已具备较高精度的优势上,运用更完善的影像技术和更稳定的配准方案还将能进一步改善种植手术的疗效。本文对计算机辅助种植外科中动静态导航的误差进行分析,并综合最新文献总结针对误差的前沿成果,以展望数字化种植能够得到更多的改善与发展。

Computer-aided implant surgery develops rapidly,but it also exposes the problem of surgical error when it is applied to dental implantation,and the solutions to the error are constantly updated.The combination of static navigation and flapless technique and application of the auxiliary micro-screw can provide better surgical results for patients with complete edentulous jaws.Dynamic navigation has the advantage of high precision,and using more perfect image technology and more stable registration scheme will further improve the efficacy of implantation surgery.In this paper,the errors of static and dynamic navigation in computer-aided implant surgery are analyzed,and the frontier achievements of the errors are summarized based on the latest literature,so as to predict the improvement and development of digital implant technology.
