摘　　要：目的 :评价高速涡轮机、微创拔牙刀在下颌阻生智牙拔除中的应用效果。方法 :选择2011年5月—2014年5月于我科实施下颌阻生智牙拔除治疗的患者83例,依据治疗方式将其分为实验组(n=42)与对照组(n=41)。对照组采用传统拔牙器械进行患牙拔除,实验组采用高速涡轮机、微创拔牙刀进行患牙拔除。观察比较2组牙根折断、牙龈撕裂、邻牙松动、舌侧骨板骨折、颌骨骨折、颞下颌关节脱位等术中并发症的发生情况,2组下唇麻木、干槽症、面颊部肿胀、开口受限等术后并发症的发生情况,以及2组手术时间、拔牙窝的完整性、疼痛VAS评分、满意度评分情况。采用SPSS19.0软件包对数据进行统计学处理。结果:实验组牙根折断、牙龈撕裂、邻牙松动、舌侧骨板骨折、颌骨骨折、颞下颌关节脱位等术中并发症发生率均显著低于对照组(P<0.05)。实验组下唇麻木、干槽症、面颊部肿胀、开口受限等术后并发症发生率也显著低于对照组(P<0.05)。实验组手术时间、拔牙窝的完整性、VAS评分、满意度评分情况与对照组相较,均有显著差异(P<0.05)。结论:高速涡轮机、微创拔牙刀用于下颌阻生智牙拔除,具有操作简单、手术难度低,创伤小、术中术后并发症少和效率高的特点,可显著降低患者对拔牙产生的恐惧感,值得临床推广。PURPOSE： To compare the results of high-speed handpiece and minimally invasive extraction in impacted mandibular third molar extraction. METHODS： From May 2011 to May 2014, 83 patients undergoing impacted mandibular third molar extraction were enrolled into the study and randomly divided into 2 groups： 42 patients in group A（experimental group） and 41 patients in group B（control group）. Group B underwent extraction with traditional method and group A underwent high-speed handpiece and minimally invasive extraction of the impacted mandibular third molar. The occurrences of the root fracture, gingival laceration, tooth mobility, lingual bone plate fracture, jaw fracture and dislocation of temporomandibular joint during operation and lower lip numbness, dry socket, facial swelling and limitation of mouth opening after operation were observed and compared between 2 groups. The operation time, integrity of extraction sockets,VAS pain score and satisfaction from patients were collected and compared. SPSS 19.0 software package was used for statistical analysis. RESULTS： The occurrences of root fracture, gingival laceration, tooth mobility, lingual bone plate fracture, jaw fracture, and dislocation of temporomandibular joint during operation in group A significantly decreased compared with group B（P 〈0.05）. The occurrences of lower lip numbness, dry socket, facial swelling and limitation of mouth opening after operation in group A significantly decreased compared with group B（P 〈0.05）. The operation time,integrity of extraction sockets, VAS pain scores and satisfaction scores in group A improved significantly compared with group B（P〈0.05）. CONCLUSIONS： High-speed handpiece and minimally invasive extraction should be widely used in impacted mandibular third molar extraction, due to the advantages of simple operation, high efficiency, minimal trauma,and few perioperative complications.
