简介：本初步研究的目的是探讨用刚性骨锚进行面罩治疗的效果。方法：6例患者（平均年龄11.8±1.1岁）在上颌骨鼻侧壁放置微型钢板。锚定系统中未掺入牙组织。在治疗开始（T1）、积极治疗结束（T2）和随访结束（T3）时评估每位患者的侧位脑电图。结果：在水平面上，平均10.8 +/- 2.4个月，平均a点移动4.8±2.0 mm。T2时，眶下区明显前移（平均3.3 +/- 1.1 mm）。在T3时，上颌骨和眶下区域的前进保持良好（平均随访时间15.2 +/- 0.9个月）。在整个治疗过程中，所有患者的微型钢板稳定性都很好。结论：在混合牙列后期，骨骼支抗结合面罩治疗可使面部中部明显改善，软组织轮廓丰满。
Introduction: The purpose of this pilot study was to investigate the effects of facemask treatment with a rigid skeletal anchor. Methods: Miniplates were placed on the lateral nasal wall of the maxilla in 6 subjects (mean age, 11.8 +/- 1.1 years). No dental tissue was incorporated into the anchorage system. Lateral cephalograms of each patient were evaluated at the beginning of treatment (T1), at the end of active treatment (T2), and at the end of follow-up (T3). Results: In the horizontal plane, mean A-point movement was 4.8 +/- 2.0 mm in a mean of 10.8 +/- 2.4 months. The infraorbital region showed significant anterior movement (mean, 3.3 +/- 1.1 mm) at T2. At T3, advancement of the maxilla and the infraorbital region was well maintained (mean follow-up time, 15.2 +/- 0.9 months). Miniplate stability was excellent in all patients throughout treatment. Conclusions: Remarkable advancement in the middle face and consequent fullness in the soft-tissue profile can be achieved by using skeletal anchorage in conjunction with facemask therapy in the late mixed-dentition period.
