Abstract

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.
