远中牙槽骨劈开法拔除上颌近中阻生智齿的临床观察

Distoangular osteotomy for extraction of impacted upper wisdom teeth

目的:探讨远中牙槽骨劈开法拔除上颌近中阻生智齿的临床疗效。方法:上颌中、高位近中阻生患者80例,120颗牙齿,随机分为两组,每组均为中位近中阻生36颗,高位近中阻生24颗。治疗组(A组)采用远中骨劈开法,对照组(B组)采用常规涡轮钻法拔除阻生牙。比较两组拔牙花费的时间、术后反应和并发症。结果:中位阻生智齿拔除,A组、B组所花费时间分别为(10.4±1.2)min、(18±2.8)min(P<0.05)。高位近中阻生智齿拔除,A组、B组所花费时间分别为(24±3.5)min、(35±5.6)min(P<0.05)。两组间术后疼痛、张口受限和面部水肿的发生差异均无统计学意义(P>0.05)。结论:远中牙槽骨劈开法拔除上颌近中阻生智齿用时短,创伤小,简单易行。

Objective To investigate the clinical effect of alveolar bone splitting technique far in the extraction of maxillary mesio impacted wisdom teeth.Methods The maxillary central,high mesioangular impaction of 80 patients,120 teeth,were randomly divided into two groups,each group are in a mesial impacted 36 star,24 star high mesioangular impaction.The treatment group（group A）using far bone splitting technique,the control group（group B） with conventional turbine drilling method of extraction of impacted tooth.Comparison of two groups of extraction time,postoperative reaction and complications.Results Median impacted wisdom tooth extraction,A group,B group,time spent,respectively（10.4±1.2） min,（18±2.8） min（P〈0.05）.High near the impacted wisdom tooth extraction,A group,B group,time spent,respectively （24±3.5）min,（35±5.6）min（P〈0.05）.Two groups of postoperative pain,trismus and facial edema showed no statistically significant difference（P〉0.05）.Conclusion The distal alveolar bone splitting method for extraction of maxillary impacted nearly in short time,small trauma,simple and easy.
