研究目的:

(1)通过镜像法构建修复体咬合面的仿生形态,运用虚拟定量回切、虚拟合架动态调合,建立后牙种植固定修复体咬合接触强度的数字化精准控制技术流程,并评价其临床效果,优化种植修复体的咬合设计流程; (2)进一步明确轻接触咬合设计的后牙种植固定修复体咬合接触随时间的纵向变化规律,为临床中种植固定修复体的咬合设计、调整和维护建立理论依据。  

Objectives of Study:

(1)To establish a digital precise control technology of occlusal contact intensity of posterior implant supported fixed prostheses by means of constructing occlusal surface via mirror method, virtual quantitative cutback, dynamic occlusal adjustment via virtual articulator, evaluate its clinical effect and optimize the occlusal design workflow for implant supported fixed prostheses; (2)To furtherly analyze longitudinal changes in occlusal contact in posterior partial fixed implant-supported prostheses with light occlusal contact design over time, and provide reference for the precise occlusion design, adjustment and maintenance of implant prostheses.

8. The patient smokes more than 10 cigarettes per day;
9. Any medical condition requiring prolonged use of steroids or bisphosphonate;
10. The patient suffers from physical handicaps or mental diseases that would interfere with the ability to perform adequate oral hygiene;
11. History of chemotherapy within 5 years prior to surgery;
12. History of radiation in the head and neck region;
13. Any conditions which would prevent the completion of study participation or interfere with analysis of study results, such as a history of non-compliance or unreliability.
