【摘要】：目的:測量并分析夜磨牙癥患者使用彈性墊治療前后各項咬合數(shù)據(jù)變化。方法:使用彈性墊對青年夜磨牙癥患者(n=10)進行治療,并在治療前和治療后6個月使用T-Scan咬合檢測儀進行咬合檢測,觀察和記錄實驗組閉合時間、分離時間、力中心位置、力不對稱指數(shù)的變化,與對照組(n=10)進行對比和研究,并觀察臨床療效。結果:治療前實驗組閉合時間及左、右側分離時間均比對照組長(P0.05),治療后均無統(tǒng)計學差異(P0.05);治療前、后2組前伸分離時間差別無統(tǒng)計學意義(P0.05);治療前實驗組和對照組力中心位置左右向偏移和右側力百分比及力不對稱指數(shù)比較均有統(tǒng)計學差異(P0.05),治療后比較均無統(tǒng)計學差異(P0.05)。實驗組治療后閉合時間及左、右側分離時間均比治療前縮短(P0.05);實驗組治療前、后右側力百分比值有統(tǒng)計學差異(P0.05),前伸分離時間、力中心位置偏移、左側力百分比及力不對稱指數(shù)治療前后比較均無統(tǒng)計學差異(P0.05)。結論:早接觸、側方干擾、全牙列力中心的偏移等咬合因素與磨牙癥有十分密切的關系。使用彈性墊治療磨牙癥,可以有效地改善上述問題,使關系更加協(xié)調和穩(wěn)定。
[Abstract]:Objective: to measure and analyze the changes of occlusal data before and after the treatment of night-molars. Methods: young patients with night-molars were treated with elastic pads before and after treatment. T-Scan occlusal tester was used to detect the occlusion before and 6 months after treatment. The changes of closing time, separation time, force center position and force asymmetry index in the experimental group were observed and recorded. The results were compared with those in the control group. Results: before treatment, the time of closure and separation of left and right sides in the experimental group were higher than those in the control group (P 0.05), and there was no significant difference after treatment (P 0.05). There was no significant difference in the time of forward extension separation between the latter two groups (P 0.05), and there were significant differences in the position of the center of force between the experimental group and the control group before treatment (P 0.05), the percentage of the right side force and the force asymmetry index were significantly different before and after treatment (P 0.05), and there was no significant difference between the two groups after treatment. After treatment, the time of closure and left, The time of right side separation was shorter than that before treatment (P 0.05), the percentage of right side force in experimental group was significantly different before and after treatment (P 0.05), the time of forward extension separation and the position of force center were deviated. There was no statistical difference between the left force percentage and the force asymmetry index before and after treatment (P 0.05). Conclusion: the occlusal factors such as early contact, lateral interference and the deviation of the center of total dentition force are closely related to molar disease. It can effectively improve the above problems and make the relationship more harmonious and stable.
