目的观察外伤性牙齿松动脱位采用不同的牙周固定术进行治疗的临床效果并对其进行分析。方法对30例患有牙外伤松动的患者共62颗牙齿采用金属丝结扎方法进行固定,对28例共50颗外伤松动的牙齿采用牙夹板固定术进行治疗,对于33例共69颗外伤松动的牙齿采用方丝弓正畸法进行固定治疗。结果持续观察一个月后金属丝结扎治疗牙齿松动的有效率为70%,牙夹板固定术治疗牙齿松动的有效率为78.57%,方丝弓正畸法治疗外伤牙齿松动的有效率为93.94%,方丝弓正畸法的有效率显著高于其他两组(P<0.05)。三个月后再次复查,金属丝结扎有效率为73.33%,牙夹板固定术治疗牙齿松动的有效率为82.14%,方丝弓正畸法治疗外伤牙齿松动的有效率为96.97%,方丝弓正畸法有效率显著高于其他两组,差异有统计学意义(P<0.05)。结论采用方丝弓正畸法治疗外伤性牙齿松动脱位较金属丝结扎治疗以及牙夹板固定术治疗效果显著。
Objective To observe the clinical effect of different periodontal fixation for traumatic tooth loosening and dislocation and to analyze the results. Methods A total of 62 teeth in 30 patients with loosened tooth trauma were fixed by wire ligation. Twenty-eight patients with 50 traumatic loose teeth were treated with dental splint fixation. For 33 patients with 69 traumatic loosening Dental square arch orthodontic method for fixed treatment. The results showed that the effective rate of loosening was 70% after the wire ligation was observed one month later, the effective rate of tooth splitting was 78.57%, the effective rate of square arch orthodontic treatment was 93.94% The efficiency of square arch orthodontic method was significantly higher than the other two groups (P <0.05). Three months after the review again, the effective rate of wire ligation 73.33%, dental splint fixation for the treatment of tooth loosening efficiency was 82.14%, square arch orthodontic treatment of traumatic tooth loosening efficiency was 96.97%, square arch Orthodontic efficiency was significantly higher than the other two groups, the difference was statistically significant (P <0.05). Conclusion The treatment of traumatic dental loosening and dislocation with square arch orthodontic treatment is more effective than ligating wire and splint fixation.
