摘要
目的:比较直接粘结颊面管与带环颊面管在直丝弓矫治技术中的临床应用。方法:选择临床病例60例共274颗磨牙,随机分成2组,分别使用直接粘接法和带环法粘结颊面管,观察一年半内颊面管脱落率,并评价治疗前后磨牙区的牙周探诊深度变化。结果:两组病例1.5年内颊面管脱落率无显著性差异,而直接粘接颊面管磨牙区牙周情况明显优于带环颊面管。结论:直接粘接颊面管的粘接强度能达到预期的矫治目标,更易于磨牙区口腔卫生的维护。
Objective： To compare the climical effect of directly bonded and soldered buccal tube in straight wire appliance. Method： 274 molars in 60 cases were divided into 2 groups randomly, the buccul tubes was bonded with direct bonding method or band method.The falling rate was observed within 1.5 year and the change of probing depth （PD） was evaluated between these two groups. Result：There was no significant difference between 2 groups as to the falling rate within 1.5 year, but the increasement of PD in direct bonding group was less than that of band one. Conclusion： Direct bonding has enough bond strength to meet the need of orthodontics, and is good for the oral hygiene.
