目的探讨运用微螺钉型种植体支抗对双颌前突畸形患者进行矫正治疗的临床应用价值。方法选取2012年2月至2014年3月期间,因双颌前突畸形来我院进行正畸治疗的成年患者共计62例,根据所选择治疗方法的不同,分为微螺钉型种植体支抗组(A组,27例)以及口外支抗组(B组,35例),并对两组的治疗效果进行比较分析。结果A组的矫正治疗时间较B组明显缩短,差异显著(P<0.05);A组患者的上唇突度、下唇突度、上唇-E线、下唇-E线以及唇间隙治疗前后变化差值均大于B组,差异显著(P<0.05);A组患者的上切牙突度、下切牙突度、上中切牙角、下中切牙角、上牙槽突度以及下牙槽突度治疗前后变化差值均大于B组,差异显著(P<0.05)。结论运用微螺钉型种植体支抗可为双颌前突畸形患者的矫正治疗提供满意的支抗作用,其临床效果较口外支抗优,值得在临床上推广应用。
Objective To investigate the clinical value of orthodontic treatment of patients with bimaxillary protrusion using micro-screw type implant support. Methods A total of 62 adult patients who underwent orthodontic treatment in our hospital from February 2012 to March 2014 were enrolled in this study. According to the different treatment options, they were divided into two groups: (Group A, n = 27) and extraoral support group (group B, n = 35). The therapeutic effects of the two groups were compared and analyzed. Results The time of correction treatment in group A was significantly shorter than that in group B (P <0.05). In group A, the variation of upper lip, lower lip, upper lip-E line, lower lip-E line and lip gap before and after treatment (P <0.05). In group A, the maxillary incisors, incisors, incisors, incisors, sulcus, The differences in the degree of groove protrusion before and after treatment were greater than those in group B, with significant differences (P <0.05). Conclusions The use of micro-screw implant anchorage can provide satisfactory support for orthodontic treatment of bimaxillary protrusion deformity. The clinical effect is superior to that of external support, which is worth popularizing in clinic.
