The leading concern of orthodontic patients is prolonged treatment with fixed appliances and demand speedy treatment from the orthodontists. Piezocision is a relatively innovative, safe and reliable technique of corticotomy in the domain of surgically-accelerated orthodontic treatment. Our aim was to compare the efficiency of piezo corticotomy (piezocision) and conventional bur in rapid orthodontic tooth movement (OTM).
The study employed a randomized, double-blind, split-mouth design. 24 subjects with Class II div 1 malocclusion were randomly assigned to the two interventions, viz; piezo and bur group. The primary parameters evaluated were the rate and amount of tooth movement and total treatment time required for canine retraction. Additionally, the duration of surgery and postoperative complications were also evaluated.
Rate and amount of tooth movement were significantly higher with reduction in total treatment time in piezo compared to bur group. The duration of surgery was significantly longer in piezo group with no significant difference observed in post-operative complications.
Piezo-guided corticotomy was effective in providing rapid OTM with profound reduction in total treatment time and may be proposed as a suitable adjuvant to conventional corticotomy having comparable post-operative complications.
正畸患者最主要的担忧是使用固定矫治器治疗时间延长，他们要求正畸医生加快治疗速度。在外科加速正畸治疗领域，压电切开术是一种相对创新、安全且可靠的皮质骨切开技术。我们的目的是比较压电皮质骨切开术（压电切开术）和传统牙钻在快速正畸牙齿移动（OTM）中的效率。
本研究采用随机、双盲、双侧对照设计。24名安氏II类1分类错牙合患者被随机分配到两种干预措施组，即压电组和牙钻组。评估的主要参数是牙齿移动的速率和量以及犬牙内收所需的总治疗时间。此外，还评估了手术持续时间和术后并发症。
与牙钻组相比，压电组的牙齿移动速率和量显著更高，总治疗时间缩短。压电组的手术持续时间明显更长，术后并发症无显著差异。
压电引导下的皮质骨切开术能有效地实现快速正畸牙齿移动，显著缩短总治疗时间，可作为传统皮质骨切开术的合适辅助方法，且术后并发症相当。
