超声骨刀微创法在拔除上颌埋伏多生牙中的临床应用

Clinical application of the piezosurgery for extraction of the impacted supernumerary teeth in the maxillary bone

目的评价超声骨刀微创法在拔除上颌埋伏多生牙中的临床疗效。方法选取2017年6月～2018年9月在我院收治的上颌埋伏多生牙48例,随机分为两组,研究组(超声骨刀微创法)和对照组(常规骨凿法),每组24例,记录术后并发症,包括疼痛、肿胀、鼻腔出血指标。结果超声骨刀组术后疼痛、面部肿胀和鼻腔出血的发生率均明显低于常规组,两组间差异均有统计学意义(P<0.05)。结论在拔除上颌埋伏多生牙时采用超声骨刀微创法可有效降低术后并发症的发生率。

Objective To infer clinical efficacy of the piezosurgery for extraction of the impacted supernumerary teeth in the maxillary bone. Methods Forty-eight patients with maxillary impacted supernumerary tooth from June 2017 to September 2018 in Hefei Stomatology Hospital were randomly divided into research group(using piezosurgery) and control group(using traditional chisel osteotomy), each group included 24 cases. Postoperative complications were compared including swelling,pain, and nasal bleeding. Results The incidence of postoperative pain, swelling and nasal bleeding in the research group was lower than the control group(P<0.05). Conclusion The application of the piezosurgery for extraction of the maxillary impacted supernumerary teeth could effectively reduce the incidence of postoperative complications.
