摘要: 目的 探讨成人双颌前突畸形患者采用微螺钉型种植体支抗治疗的临床疗效。方法 双颌前突畸形患者100例,随机数字表法分为2组,对照组50例,采用传统口外加强支抗方案进行治疗;实验组50例,采用微螺钉型种植体支抗进行治疗。比较2组患者治疗后的唇部软组织,上、下颌牙槽突,牙列及上、下颌骨变化状况。采用SPSS19.0软件包对数据进行t检验。结果 实验组患者的治疗时间为(18.84±2.61)个月,显著短于对照组的(24.72±2.32)个月;治疗后实验组患者的上唇、下唇突度差值,上唇、下唇-E线差值,唇间隙差值均显著高于对照组(P<0.05);治疗后实验组患者的上切牙、下切牙突度差值,上、下中切牙角差值,上、下牙槽突度差值均显著高于对照组(P<0.05)。结论 成人双颌前突畸形患者采用微螺钉型种植体支抗治疗疗效显著,值得临床推广应用。

Abstract: PURPOSE: To investigate the clinical effect of micro screw implant anchorage in the treatment of adult patients with double jaw protrusion. METHODS: A total of 100 adult patients with bimaxillary protrusion were stratified into micro screw implant anchorage group (n=50) and extraoral anchorage group (n=50) according to different treatment methods. The differences of lip protrusion, upper alveolar protrusion and lower alveolar protrusion, dentition,mandible and maxilla were evaluated after treatment. SPSS 19.0 software package was performed for data analysis. RESULTS: The treatment duration of micro screw implant anchorage group and extraoral anchorage group was (18.84±2.61) month and (24.72±2.32) months, respectively, which was significantly different (P<0.05). The difference of upper lip protrusion, lower lip protrusion, upper lip-E line, lower lip-E line and lip gap before and after treatment were significant between 2 groups. The differences of the upper incisors protrusion, lower incisors protrusion, the upper central incisors angle, the lower central incisors angle, upper alveolar protrusion and lower alveolar protrusion before and after treatment in micro screw implant anchorage group were significantly greater than those in extraoral anchorage group (P<0.05). CONCLUSIONS: The clinical effect of micro screw implant anchorage in the treatment of adult patients with double jaw protrusion deformity is significant, which is worthy of clinical application.
