目的:分析直丝弓托槽倒置粘接改正上前牙腭侧错位牙的实际效果。方法:选取96例上前牙腭侧错位患者为研究对象,按照随机数表法将其随机分为对照组和分析组各48例,所有患者均使用直丝弓带环进行临床矫正,对照组采用直丝弓托槽对患者牙齿进行固定,分析组采用方丝弓托槽对患者牙齿进行固定。对比两组患者满意度以及治疗效果,具体测量中央窝与弓丝距离,分析两组患者矫正治疗后上下牙的邻接关系。结果:分析组上下颌中央窝与弓丝距离的两次测量值均远低于对照组,差异有统计学意义(P<0.05),上下牙邻接关系远优于对照组,差异有统计学意义(P<0.05);分析组满意率远高于对照组,差异有统计学意义(P<0.05)。结论:直丝弓托槽倒置粘接矫正上前牙腭侧错位牙的临床效果更佳,患者上下牙邻接更严密,且显著提高了患者的满意度。
OBJECTIVE: To analyze the actual effect of orthosis of orthodontic appliance on the palatal dislocation of the anterior teeth. Methods: Ninety-six cases of anterior palatal misplaced patients were selected as study subjects. According to the random number table, they were randomly divided into control group and analysis group, 48 cases in each group. All cases were corrected with straight- The orthodontic brackets were used to fix the patient’s teeth. The analysis group was fixed with square arch brackets to the patient’s teeth. The satisfaction of two groups of patients and the treatment effect were compared. The distance between the central fossa and the archwire was measured, and the adjacent relationship between the upper and lower teeth after orthodontic treatment was analyzed. Results: The measured distance between the central fossa of maxilla and mandible and arch wire were much lower than that of control group (P <0.05), and the superior and inferior teeth abutment was much better than that of control group, the difference was statistically significant (P <0.05). The satisfaction rate of the analysis group was much higher than that of the control group, with significant difference (P <0.05). Conclusion: The orthodontic treatment of orthodontic tooth palatal dislocation with orthodontic wire brackets is more effective. The upper and lower teeth of patients are more closely adjacent to each other and the patient satisfaction is significantly improved.
