摘要:

目的探讨咬合因素对女性开!患者中颞下颌关节紊乱病( TMD)发病的影响。方法选取女性开!患者102名,根据TMD的有无分为两组,伴有TMD的试验组有59名患者;不伴有TMD的对照组有43名患者。采用咬合力测试仪对两组患者进行咬合力、咬合接触面积、每一咬合接触点上的平均咬合压强和咬合重心的测试,并通过SPSS 11.0软件进行统计学分析。结果试验组的咬合力和咬合接触面积均小于对照组,两组间每一咬合接触点上的平均咬合压强和咬合重心的偏移无统计学差异。结论咬合力不足与开!女性TMD的发病有关。

Abstract:

Objective To investigate the effect of occlusal force on the etiology of open bite patients who suffer from temporomandibular disorde(rs TMD). Methods One hundred and two women patients with open bite were divided into TMD( +) group and TMD( - ) group according to patients with or without TMD. Occlusal force, occlusal contact areas, occlusal average pressure and occlusal center were evaluated with pressure sensitive sheets. The results were analyzed by SPSS 11.0 statistic software. Results Occlusal force and occlusal contact areas in TMD( +) group were significantly lower than that in TMD( - ) group. Occlusal average pressure and occlusal center had no significance between two groups. Conclusion The results indicate that the decrease of occlusal force and occlusal contact areas may have some relationships with TMD in open bite patients.
