摘要/Abstract

摘要： 目的: 为提高标准型人工颞下颌关节窝假体植入的稳定性,进行关节窝植骨并评价其应用效果。方法: 2013年11月—2014年2月间收治的经计算机辅助测量设计并进行人工关节置换的8例患者,采用关节窝植骨代替关节窝骨磨削的方法进行手术技术改进,通过计算假体的骨接触面积,评价植骨法对提高关节窝假体植入稳定性的作用。植骨术后CT模拟测量评价假体骨接触面积变化,评价其稳定性,并利用SPSS 19.0软件包中的配对t检验评价是否有统计学差异。结果: 采用关节窝植骨法假体术中就位稳定,术后CT测量显示,关节窝假体的骨接触面积比磨骨法增加34.85%（P<0.05）。结论: 关节窝植骨可以显著提高人工关节窝假体的稳定性。

Abstract: PURPOSE: To investigate the value of bone grafting in glenoid fossa to improve the stability of Biomet fossa prosthesis implantation. METHODS: Patients who needed total temporomandibular joint replacement surgery from Nov. 2013 to Feb. 2014 were included in this study. Bone grafting in glenoid fossa was performed on each patient instead of conventional bone trimming on articular tubercle. Postoperative measurement of bone attachment area of articular tubercle, bone graft and the top of fossa prosthesis was performed using the ProPlan CMF 1.4 software to determine the stability of the fossa prosthesis. Immediate CT was taken and imported into Proplan software again to evaluate the outcome of bone grafting, Student’s t test was used for statistical analysis with SPSS 19.0 software package. RESULTS: The intraoperative stability of fossa prosthesis was guaranteed and postoperative measurement showed that bone grafting in glenoid fossa increased bone attachment rate of 34.86% than the bone trimming on articular tubercle (P<0.05). CONCLUSIONS: Bone grafting in glenoid fossa could significantly improve the stability of Biomet fossa prosthesis with a reliable outcome.
