摘要:
目的:探讨正畸治疗的上颌前突患者上颌牙牙根吸收及牙槽骨改建情况。方法:选取上颌前突患者15例,均拔除上下颌第一前磨牙进行治疗。治疗前及拔牙间隙关闭后分别拍摄CBCT,观察牙根吸收及中切牙区牙槽骨改建情况。结果:拔牙间隙关闭后,所有患者均被检测出有牙根吸收,中切牙、侧切牙、尖牙和第二前磨牙吸收量分别为(0.415±0.118)、(0.972±0.288)、(0.466±0.718)和(0.283±0.339)mm。在中切牙颈部唇侧、根尖舌侧牙槽骨增厚,颈部舌侧、根中唇侧、根尖唇侧牙槽骨变薄,牙齿倾斜移动; 在颈部、根中部以及根尖部水平总牙槽骨厚度的改变不具有统计学意义(P>0.05)。结论:正畸治疗后几乎所有牙齿均有一定程度的牙根吸收。前牙在内收过程中倾斜移动。
Abstract:
Aim: To evaluate orthodontically induced apical root resorption and alveolar bone reconstruction in maxillary teeth.Methods: A total of 15 patients receiving standardized orthodontic fixed appliance treatment with straight wire technique and first premolar extraction. Cone beam computed tomography(CBCT)examination was performed before and after closing the extraction space to observe the prevalence and severity of apical root resorption and alveolar bone reconstruction of central incisor.Results: After closing the spaces, apical root resorption was detected in all the patients; the apical root resorption values of central incisor,lateral incisor,canine and second premolar were(0.415±0.118),(0.972±0.288),(0.466±0.718)and(0.283±0.339)mm, respectively. Alveolar bone width increased significantly at the coronal level of labial side and the apical level of lingual side, decreased at the coronal level of lingual side and the apical level of labial side, and the teeth tipping moved; but the total alveolar bone width changes had no significance at coronal level,midroot level and apical level(P>0.05).Conclusion: Apical root resorption maybe exists in almost all the teeth after orthodontic treatment, and anterior teeth show a tilting movement during adduction.
