摘要：

背景：TeeTester和T-ScanⅢ两种咬合分析仪在口腔临床各领域已被广泛应用，国内对两种仪器的使用尚未见到对比数据。
目的：应用TeeTester与T-ScanⅢ两种咬合分析仪研究正常牙合青年学生的咬合特征，并比较两系统咬合分析的差异。
方法：采用TeeTester咬合系统V3.2.0记录13例正常牙合受试者在牙尖交错位状态下的左右侧咬合力分布百分比、牙合力中心点位置、牙合力不对称指数、前牙咬合力占牙合力总值的百分比，采用T-ScanⅢV8.01咬合分析仪记录13例正常牙合受试者在ICP时的上述指标，并在25%，50%，75%，100%最大咬合力时的4个时段对上述各项指标进行分析。检测数据导入SPSS19.0软件进行统计。
结果与结论：①TeeTester与T-ScanⅢ两系统所测得的左右侧咬合力分布百分比差异均无显著性意义(P > 0.05)。②两系统所测得的所有受试者牙合力中心点绝大多数在规定灰圈内，且均位于前磨牙区。两系统所测得   牙合力中心点距中线的垂直距离、牙合力中心点偏移方向，差异均无显著性意义(P > 0.05)。③两系统所测得的牙合力不对称指数差异无显著性意义(P > 0.05)。④TeeTester所测得的前牙咬合力占总牙合力的百分比大于T-ScanⅢ所测结果，且在50%，75%，100%最大咬合力时差异有显著性意义(P < 0.05)。结果说明，①正常牙合者左右侧咬合基本平衡。②左右侧咬合力分布百分比、牙合力中心点、牙合力不对称指数可以作为临床上判断咬合是否正常的指标。③TeeTester与T-ScanⅢ在前牙咬合力占总牙合力百分比的测量方面存在差异,需要继续关注和研究。

Abstract:

BACKGROUND: TeeTester and T-ScanIII have been widely used in clinical stomatology, but there is no report on the contrast data of these two occlusal systems in China.
OBJECTIVE: To investigate and compare the occlusal characteristics of young students with normal occlusion by using TeeTester and T-ScanIII.
METHODS: Thirteen subjects with normal occlusion received examination by TeeTester V3.2.0, and another 13 subjects underwent examination by T-ScanIII V8.01. The two systems were used to record the following parameters: occlusal force percentage in the left and right sections, center of force, asymmetry index of occlusal force, and the proportion of the anterior tooth occlusal force in total at intercuspal position. Above-mentioned parameters were analyzed at 25%, 50%, 75% and 100% of maximum occlusal force using SPSS 19.0 software.
 
RESULTS AND CONCLUSION: (1) Occlusal force percentage in the left and right sections had no significant differences in TeeTester and T-ScanIII (P > 0.05). (2) The centers of force were mostly within the gray ellipse, and all in premolar region. The vertical distance from the center of force to the center line and the excursion direction recorded by TeeTester and T-ScanⅢ had no significant differences (P > 0.05). (3) Asymmetry index of occlusal force recorded by the two systems had no significant differences (P > 0.05). (4) The proportion of the anterior tooth occlusal force in total recorded by TeeTester was higher than that recorded by T-ScanIII and the differences at 50%, 75% and 100% of maximum occlusal force were significant (P < 0.05). These findings indicate that the occlusion of subjects with normal occlusion is balanced generally; the occlusal force percentage in the left and right sections, center of force, and asymmetry index of occlusal force can be used to estimate the occlusal state in dental clinical conditions; the TeeTester and T-ScanIII systems have differences in the proportion of the anterior tooth occlusal force that needs continued attention and research.
