摘　　要：目的分析颌骨骨折内固定术后咬合不良的危险因素,并提出预防建议。方法回顾性分析医院2015年1月至2018年1月收治的101例实施内固定术的颌骨骨折患者的临床资料,根据咬合关系恢复情况将患者分为预后良好组和预后不良组,采用描述性检验和Logistic回归分析法明确咬合不良的危险因素。结果 101例患者中,有20例发生术后咬合不良,发生率为19.80%;单因素分析结果显示,预后不良组年龄>60岁、多处骨折、粉碎性骨折、复位不准确、术后无颌间牵引、术后无颌间固定、术者工龄<3年构成比高于预后良好组(P<0.05);Logistic回归分析结果显示,上述因素均是影响患者术后咬合不良的独立危险因素(P<0.05)。结论年龄>60岁、骨折部位、粉碎性骨折、复位情况、术后颌间牵引、术后颌间固定、术者工龄<3年均是影响颌骨骨折内固定术后咬合不良的独立危险因素,需制定针对性预防措施。Objective To analyze the risk factors of malocclusion after internal fixation of jaw fractures and to provide preventive suggestions. Methods The clinical data of 101 patients with jaw fractures and implement internal fixation from January 2015 to January 2018 were retrospective analysis. According to the recovery of malocclusion, patients were divided into good prognosis group and bad prognosis group. Descriptive test and Logistic regression analysis were used to identify the risk factors of malocclusion. Results Among 101 patients, 20 cases had malocclusion, and the incidence was 19.80%.The univariate analysis showed that the proportion of age >60, multiple fractures, comminuted fractures, inaccurate reduction, no intermaxillary traction, no intermaxillary fixation and less than 3 years of operator’s service in the bad prognosis group were higher than those in the good prognosis group(P<0.05);the Logistic regression analysis showed that the above factors were independent risk factors of malocclusion after operation(P<0.05). Conclusion Age>60, fractures site,comminuted fractures, reposition condition, postoperatively intermaxillary traction, postoperatively intermaxillary fixation,and less than 3 years of operator’s service are the independent risk factors of malocclusion after internal fixation of jaw fractures, and targeted preventive measures need to be formulated.
