摘　　要：目的:采用T-ScanⅢ[牙合]力分析仪观测分析牙隐裂患者的咬合功能状况。方法:分别选取30例左侧下颌第一磨牙有隐裂的患者(隐裂组)和30例无隐裂牙的正常[牙合]者(对照组),使用T-ScanⅢ[牙合]力分析仪观测隐裂组和对照组[牙合]力的分布规律。结果:牙尖交错位时,对照组[牙合]力均匀平衡,而隐裂组[牙合]力中心偏向隐裂侧,隐裂组与对照组的[牙合]力存在显著性差异(P<0.05);隐裂组与对照组[牙合]干扰也有显著性差异(P<0.05)。结论:两侧[牙合]力不平衡以及[牙合]干扰是发生牙隐裂的重要因素。Objective:Measurement of occlusal function used in the patients with cracked teeth byT-ScanⅢ.Methods:Thirty patients with craked in first molars of the left mandibular(study group)and 30 normal teeth without cracked(control group)were selected respectively.The distribution of the force in both two groups were observed by T-ScanⅢforce analyzer.Results:During intercuspal position,the forces on both sides of the control group were equal,while the center of forces in the study group was inclined to the cracked side,and there was significant difference between the cracked teeth group and the control group(P<0.05),and the interference between the two groups was also significant(P<0.05).Conclusion:The imbalance of occlusal force and the interference of lateral occlusion are the important occlusal factors of cracked teeth.
