三种方法治疗外伤性松动脱位前牙的临床疗效比较

Comparison of curative effect among three fixation methods for injured teeth

目的对比方丝弓托槽、钢丝树脂夹板、玻璃纤维树脂夹板三种材料对外伤性松动脱位前牙的临床疗效。方法收集60例前牙外伤的患者,随机分为三组,A组采用方丝弓托槽固定松动脱位牙;B组采用玻璃纤维树脂夹板固定松动脱位牙;C组对照采用钢丝树脂夹板固定松动脱位牙。三组患者随访半年,评估每种固定术的疗效。结果三组松牙固定术的总有效率比较差异有统计学意义(P<0.05)。方丝弓托槽组、玻璃纤维树脂夹板组、钢丝树脂夹板组病例治疗前、后牙周指数比较的差异有统计学意义(P<0.05)。方丝弓托槽组和玻璃纤维树脂夹板组优于钢丝树脂夹板组(P<0.05)。三组临床操作时间长短有差异,方丝弓托槽组和玻璃纤维树脂夹板组操作时间较钢丝树脂夹板组短(P<0.05)。结论方丝弓托槽和玻璃纤维树脂夹板操作简单,易于清洁,固定效果较好,值得临床推广使用。

Objective To evaluate the effectiveness among the edgewise brackets,steel wire resin splint and glass-fiber resin splint on firming luxation of the incisor. Methods 60 patients of traumatic luxation teeth were randomly divided into two groups. Group A： Edgewise brackets were used to fix teeth. Group B： Glass-fiber resin splint were used to fix teeth. Group C： Steel wire resin splint were used to fix teeth. The three groups of patients were followed up for half a year in order to assess the efficacy. Results The efficiency among three groups had significantly different（ P 0. 05）. The periodontal index in the edgewise brackets group,steel wire resin splint group and glass-fiber resin splint group had significantly different during the treatment period（ P 0. 05）. The edgewise brackets group and glass-fiber resin splint group are superior to the steel wire resin splint group（ P 0. 05）. There are differences among the three groups of clinical operation duration,the edgewise brackets group and glass-fiber resin splint group are shorter than the steel wire resin splint group（ P 0. 05）.Conclusions Edgewise brackets are simple to operate,easy to clean,is worthy for being widely used in treatment of trauma teeth.
