摘要: 目的:比较金属丝结扎法(A)、牙弓夹板法(B)、钢丝釉质粘合剂法(C)、片段方丝弓技术松牙固定法(D)、Super-bond C&B邻间隙粘结法(E)在外伤后严重松动或脱位牙固定中的疗效。方法:选择因外伤导致牙齿Ⅱ~Ⅲ度松动或牙完全脱位的患者187例共计486颗患牙, 其中根冠折拔除12颗(不计入统计),随机采用A、B、C、D、E法进行固定,观察疗效。结果:A、B、C、D、E组治疗前后牙周健康指标未见显著性差异(P>0.05)。松牙固定6周后E组的GI和SBI均显著低于 A、B、C、D组,差异有统计学意义(P<0.05);A、B、C、D组间牙龈指数(GI)、龈沟出血指数(SBI)比较,差异无统计学意义(P>0.05)。半年后A、B、C、D、E组的GI、SBI差异无统计学意义(P>0.05)。治疗6周后A、B、C、D组有效率均低于E组,差异均有统计学意义(P<0.05);半年后与去除固定装置时比较,各组有效率的差异无统计学意义(P>0.05)。结论:Super-bond C&B邻间隙粘结法(E)是一种无牙周刺激性,更清洁美观,更高效的松动牙或脱位牙固定方法。

Abstract: Objective: To compare the effects of wire ligation (A), dental splint method (B), steel enamel adhesive method (C), fragment edgewise technique loose teeth fixed method (D), Super-bond C & B gap bonding method o (E) in serious injury or dislocation of loose teeth fixation. Methods: Fixed effects of 187 cases (486 teeth), the trauma resulting in loose teeth Ⅱ ~ Ⅲ degree or complete dislocation, and treated by A, B, C, D or E method, were observed. Results: Comparing of A, B, C, D, E group before treatment, there  was no significant difference in their periodontal health indicators(P>0.05). Six weeks after teeth fixed, GI and SBI [(0.79±0.47), (1.39 ±0.57)] of group E were significantly lower than those of group A, B, C, D [(1.52±1.26), (1.49±1.30); (1.51±1.26); (1.53±1.23), (1.81±0.72), (1.89±0.68), (1.73±0.78), (1.74±0.74)], the difference was statistically significant (P<0.05). Among A, B, C, D groups, the difference of GI and SBI has no statistically significant (P>0.05). After six months, there was no significant difference among A, B, C, D, E groups in GI and SBI (P>0.05). After six weeks effective rates of group A [(50/66), 75.76%], B [(59/74), 79.73%], C [(71/82), 86.59%], and D [(86/97), 88.66%] were lower than that of group E [(154/155), 99.35%], the difference was statistically significant (P<0.05). Six months after removing of fixation, there was in no significant difference in removal efficiency among all groups (P>0.05). Conclusion: Super-bond C & B gap bonding (method E) is a non-irritating periodontal, cleaner appearance, more efficient or avulsed teeth loose teeth fixed method.
