目的：探讨种植支抗非拔牙矫治成人上颌前突畸形的临床疗效。方法分析50例上颌前突畸形成人患者临床资料，依据支抗不同进行临床分组，对照组(传统强支抗组)20例和观察组(种植支抗非拔牙矫治组)30例。结果观察组上颌前突患者上中切牙切缘到Y轴的距离(U1-Y)、下中切牙切缘到Y轴的距离(L1-Y)、上第一磨牙冠近中点到Y轴的距离(U6-Y)、下中切牙长轴和下颌平面所形成的后上夹角(L1-MP)、上、下中切牙长轴之间的夹角(U1-L1)优于对照组，差异均有统计学意义(P<0.05)。结论不锈钢微螺钉种植系统矫治成人上颌前突畸形效果明显，值得临床推广应用。

Objective To investigate the clinical effect of implant anchorage non extraction in correction of adult maxillary protrusion deformity.Methods The clinical data of 50 adult patients with maxillary protrusion deformity patients were analyzed. According to different anchorages, they were divided into control group (traditional strong anchorage group) with 20 cases and observation group (implant anchorage non extraction correction group) with 30 cases.Results The indexes of upper incisor incisal edge to Y axis (U1-Y), low incisor incisal edge to Y axis (L1-Y), upper first molar dental crown midpoint to Y axis (U6-Y), posterosuperior included angle between low incisor long axis and mandibular plane (L1-MP), and angle between long axis of upper incisor and low incisor (U1-L1) of adult maxillary protrusion deformity patients were better in the observation group than the control group, and the difference had statistical significance (P<0.05).Conclusion The effect of correction adult maxillary protrusion deformity by implant anchorage is obviously, and it is worth clinical promotion and application.
