目的比较固定矫治中使用带环和直接粘接颊面管的应用效果。方法回顾163例固定矫治病例中磨牙带环和直接粘接颊面管的脱落情况,检查磨牙牙周状况,测量磨牙带环间隙,并进行统计学分析。结果带环脱落率为16.73%,直接粘接颊面管脱落率为14.53%,两者差异无统计学意义(P>0.05);与粘接颊面管磨牙相比粘接带环磨牙的牙周状况较差,两组的出血指数、探诊深度具有统计学差异(P<0.01);带环拆除后遗留明显的带环间隙。结论固定矫治中使用直接粘接颊面管有利于牙周状况的维护,粘接效果可靠,而且避免了分牙过程和带环间隙的遗留。
Objective To compare the effect of using band ring and direct adhesive buccal tube in fixed orthodontic treatment. Methods 163 cases of fixed orthodontic treatment of molar banding and direct bonding buccal tube detachment, check the periodontal status of the molar, measuring molar ring space, and statistical analysis. Results The rate of band-ring detachment was 16.73%, and the rate of ablation of direct bond buccal tube was 14.53%. There was no significant difference between the two groups (P> 0.05). Compared with adhesive buccal canal molar, The week status was poor. Bleeding index and probing depth had statistical difference between the two groups (P <0.01). Conclusion The use of direct adhering buccal tube during orthodontic treatment is good for the maintenance of periodontal condition. The bonding effect is reliable, and it avoids the process of tooth decay and the residual of belt ring gap.
