摘　　要：目的:探讨压电骨皮质切开术即Piezocision技术在解除下牙列拥挤病例中的疗效。方法:选择需减数四颗第一前磨牙进行矫正治疗的错牙合畸形患者20例,平均分为Piezocision组10例和传统正畸组10例,对两组下牙列拥挤的排齐时间、牙根吸收及术后的疼痛不适进行对比,使SPSS 16.0统计软件进行数据分析。结果:Piezocision组下牙列拥挤解除所需时间(93.10±10.20)d较传统矫正疗程(120.30±8.01)d短,差异具有统计学意义(P<0.05),牙列排齐前后两组牙根长度均无明显吸收,差异无统计学意义(P>0.05),Piezocision组术后1周内患者诉疼痛不适和术区肿胀,但不影响正常生活。结论:Piezocision技术能够加速解除下牙列拥挤,且不伴发牙根吸收发生的风险,患者对该技术在治疗中应用的接受度较高。Objective To evaluate the efficiency of Piezocision（a minimally invasive corticotomy）assisted orthodontics in relieving the mandibular crowding. Methods 20 patients with malocclusion requiring orthodontic treatment by extracting 4 premolars were selected and divided into two groups： Piezocision group and traditional orthodontic group.Time needed for alignment, root resorption and postoperative discomfort were compared, SPSS 16.0 statistical software were usd for data analysis. Results In Piezocision group, the time needed to relieve the crowding of mandibular dentition was shorter than that of traditional orthodontic treatment, the difference was statistically significant, P〉0.05. After dentition alignment,the length of rootin both group showed no statistically significant, P〈0.05. The Piezocision group patients complained of slightly pain and intraoperative swelling, within 1 week after surgery but does not affect normal life. Conclusion Piezocision technology accelerates the alleviating of mandibular crowding and reduces the risks of root resorption compared with traditional orthodontic.Meanwhile the patients showed positive acceptance of the Piezocision in the treatment.
