树脂夹板加不锈钢丝固定外伤松动上切牙的疗效观察

Clinical effect of resin splint with stainless steel sil on stabilization of traumatic loose upper incisors

目的观察树脂夹板+不锈钢丝和牙弓夹板固定外伤松动上切牙的临床疗效。方法随机将36例外伤上切牙松动患者,共52颗牙分成两组,分别用树脂夹板+不锈钢丝固定法(试验组)和牙弓夹板固定法(对照组)固定,观察疗效。结果 6个月随访观察发现,试验组的有效率明显高于对照组(P<0.05);两组固定方法治疗后的龈沟出血指数(SBI)、牙龈指数(GI)、菌斑指数(PLI)差异有统计学意义(P<0.01),试验组明显优于对照组。结论树脂夹板+不锈钢丝固定法是一种牙周刺激性小和疗效优良的松动牙固定方法。

Objective To compare the clinical effect of traumatic loose upper incisors by fixation of resin splint with stainless steel sil and fixation of dental arch splint. Methods 52 teeth were randomly divided into two groups, fixed by resin splint with stainless steel sil and dental arch splint, respectively. The clinical effect was evaluated. Results Effect of the experimental group were better than that of the control group on stabilization of traumatic loose upper incisors in 6- month follow-up（P〈0.05）. SBI, GI and PLI of the experimental group was significantly better than that of the control group（ P〈0.01）. Conclusion The resin splint with stainless steel sil is effective for fixation of loose teeth with the smal- ler periodontium irritation.
