To evaluate the effectiveness of a new surgical technique in the treatment of palatally impacted canines.
Six consecutive patients presenting with bilaterally impacted canines were compared. One canine was surgically exposed using a conventional surgical technique while the contralateral canine was exposed using a corticotomy-assisted technique.
After tooth movement was completed, statistical comparisons of the two methods revealed a reduction of treatment time of 28-33% for the corticotomy-assisted canines. No significant differences were observed in final periodontal condition between the canines exposed by these two methods.
This preliminary study supports the concept that a corticotomy-assisted surgical technique helps reduce orthodontic treatment time for palatally impacted canines.
评估一种新的外科技术治疗腭侧阻生尖牙的有效性。
对6例双侧阻生尖牙患者进行比较。一侧尖牙采用传统外科技术进行手术暴露,而对侧尖牙采用皮质骨切开辅助技术进行暴露。
牙齿移动完成后,两种方法的统计学比较显示,皮质骨切开辅助技术暴露的尖牙治疗时间缩短了28% - 33%。两种方法暴露的尖牙在最终牙周状况方面未观察到显著差异。
这项初步研究支持皮质骨切开辅助外科技术有助于缩短腭侧阻生尖牙正畸治疗时间这一概念。
