摘要
目的探讨一侧上颌骨缺损患者赝复体修复后的咬合力分布状况。方法以2007～2009年因一侧上颌骨缺损制作支架中空式永久性赝复体修复的患者为研究对象。采用T-scanⅡ咬合分析仪测定患者咬合加载时间(MLT)及咬合力分布状况。结果赝复体戴入前后咬合加载时间差异无统计学意义(P>0.05)。赝复体戴入后咬合力中心(COF)向缺损侧偏移约3.9mm,缺损区可承受约12.67%的咬合力,同戴入前相比差异均有显著统计学意义(P<0.01)。结论赝复体修复一侧上颌骨缺损一定程度上改善了患者的咬合力分布。
Objective To observe the distribution of occlusal force of patients with obturators. Methods Fifteen unilateral maxillary defect patients with obturators were recruited for this study. The distribution of occlusal force was observed with T-Scan 11 Computerized Occlusal Analysis system. Results The difference of MLT was not significant for patients with and without obturators （P〉0.05）. With obturators, the COF moved to defective side about 3.9mm and the defective side could bear 12.67% occlusal force （P〈0.01）. Conclusion The occlusal force distribution of unilateral maxillary defect Patients was improved by wearin obturators .
