简介：该研究的目的是阐明新开发的微创手术（压电穿刺术）是否是加速上颌骨和下颌骨牙齿移动的合理修改。方法：10只比格犬分为2组。对照组进行传统正畸牙齿移动。在实验组中，使用压电刀在移动牙齿周围的牙龈上进行皮质穿刺。在第 1 周至第 6 周进行测量。通过独立 t 检验评估组织形态计量学分析中的牙齿移动和骨附着率。结果：压电穿刺组的累积牙齿移动距离比对照组大：上颌骨为3.26倍，下颌骨为2.45倍。压电穿刺在所有观察时间都显着加速了牙齿的移动，并且上颌骨的前两周和下颌骨的第二周加速度最大。压电穿刺也增加了合成代谢活性：上颌骨增加 2.55 倍，下颌骨增加 2.35 倍。结论：根据压电穿刺对上颌和下颌的不同影响，采用优化方案的压电穿刺临床试验结果可能会给正牙医生带来缩短治疗时间的治疗益处。
Introduction: The aim of the study was to elucidate whether a newly developed, minimally invasive procedure, piezopuncture, would be a logical modification for accelerating tooth movement in the maxilla and the mandible. Methods: Ten beagle dogs were divided into 2 groups. Traditional orthodontic tooth movement was performed in the control group. In the experimental group, a piezotome was used to make cortical punctures penetrating the gingiva around the moving tooth. Measurements were made in weeks 1 through 6. Tooth movement and bone apposition rates from the histomorphometric analyses were evaluated by independent t tests. Results: The cumulative tooth movement distance was greater in the piezopuncture group than in the control group: 3.26-fold in the maxilla and 2.45-fold in the mandible. Piezopuncture significantly accelerated the tooth movements at all observation times, and the acceleration was greatest during the first 2 weeks for the maxilla and the second week for the mandible. Anabolic activity was also increased by piezopuncture: 2.55-fold in the maxilla and 2.35-fold in the mandible. Conclusions: Based on the different effects of piezopuncture on the maxilla and the mandible, the results of a clinical trial of piezopuncture with optimized protocols might give orthodontists a therapeutic benefit for reducing treatment duration.
