目的探讨自锁托槽矫治器在牙颌畸形患者正畸治疗中的应用价值。方法选取2010年6月至2011年6月于大连市口腔医院治疗的86例牙颌畸形患者作为研究对象,按随机数字表法将其分为观察组和对照组,各43例。观察组患者采用自锁托槽矫治器进行治疗,对照组患者使用传统金属托槽,比较两组患者菌斑指数、牙龈指数、龈沟出血指数、矫治初期疼痛程度、托槽脱落情况及龈沟液天冬氨酸转氨酶(AST)含量。结果治疗3个月及7个月后,观察组患者的菌斑指数、牙龈指数、龈沟出血指数均明显低于对照组,差异均有统计学意义(均P<0.05);观察组患者矫治初期疼痛视觉模拟量表(VAS)评分明显低于对照组,差异有统计学意义(t=45.575,P=0.000);治疗1年、3年、5年后,观察组患者的托槽脱落率均明显低于对照组,差异均有统计学意义(均P<0.05);放置矫治器24 h、72 h后,观察组患者龈沟液AST含量均明显低于对照组,差异均有统计学意义(均P<0.05)。结论牙颌畸形患者使用自锁托槽矫治器正畸,牙周指数改善明显,矫正初期疼痛程度低,托槽脱落率低,效果显著。
Objective To investigate the value of self-ligating brackets orthodontics in the treatment of orthodontics. Methods 86 cases of dento-mandibular deformities treated in Dalian Stomatological Hospital from June 2010 to June 2011 were selected as the research objects, and divided into observation group and control group according to the random number table method, with 43 cases in each. Patients in the observation group were treated with self-ligating brackets appliance. Patients in the control group were treated with traditional metal brackets. The plaque index, gingival index, sulcus bleeding index, initial pain degree, brackets off and gingival sulcus Liquid aspartate aminotransferase (AST) content. Results After 3 months and 7 months of treatment, the plaque index, gingival index and gingival sulcus bleeding index in the observation group were significantly lower than those in the control group (all P0.05) The visual analog scale (VAS) score of initial pain was significantly lower than that of the control group (t = 45.575, P = 0.000). After 1, 3 and 5 years of treatment, Were significantly lower than the control group, the difference was statistically significant (all P <0.05); placed appliance 24 h, 72 h after treatment, the observation group patients with gingival crevicular fluid AST levels were significantly lower than the control group, the difference was statistically significant Significance (all P <0.05). Conclusions Dental orthodontics patients using orthodontic brackets orthodontic, periodontal index improved significantly, the initial stage of orthodontic pain is low, the bracket off rate is low, the effect is significant.
