This case report describes the use of an osseointegrated implant to maximize anchorage in a 24-year-old female orthodontic patient with an Angle Class II, Division 1 malocclusion. Preadjusted edgewise appliance therapy was performed by extraction of only the maxillary first premolars. The osseointegrated implant was placed in the median-sagittal region of the hard palate for maximum orthodontic anchorage and connected to maxillary first molar bands via a transpalatal arch. Total treatment time was 2 years and 8 months. Cephalometric superimposition revealed the achievement of maximum molar anchorage in the maxilla, resulting in satisfactory occlusal and facial improvements. Histological analysis of the implant-bone interface demonstrated that the fixture was successfully osseointegrated. In conclusion, the osseointegrated implant placed in the median-sagittal palate was shown to be an effective orthodontic system that can be used clinically as a rigid intraoral anchorage.
本病例报告描述了在一名24岁安氏II类1分类错牙合畸形的女性正畸患者中,使用骨整合种植体以最大限度地增强支抗。仅拔除上颌第一前磨牙,采用预成方丝弓矫治器进行治疗。骨整合种植体植入硬腭正中矢状区域以获得最大的正畸支抗,并通过腭弓与上颌第一磨牙带环相连。总治疗时间为2年8个月。头影测量重叠分析显示在上颌实现了最大程度的磨牙支抗,咬合和面部改善效果令人满意。种植体-骨界面的组织学分析表明种植体成功实现了骨整合。总之,置于硬腭正中矢状位的骨整合种植体是一种有效的正畸系统,可作为口腔内的坚固支抗在临床上使用。
