Protraction of posterior teeth to close the spaces in patients with congenitally missing maxillary lateral incisors is challenging. Mini-implants are a reliable source of anchorage for this purpose. This case report demonstrates the application of a T-bar protraction appliance with a palatal mini-implant for en masse protraction of posterior teeth into the lateral incisor space in an adolescent patient. The patient's occlusion and esthetics were significantly improved, and ideal overjet and overbite were obtained after 30 months of treatment. Follow-up records six months after the completion of the treatment displayed stable results.
对于先天性上颌侧切牙缺失的患者,后牙前移以关闭间隙具有挑战性。微型种植体是实现这一目的可靠支抗来源。本病例报告展示了一种带腭部微型种植体的T形杆前移矫治器在一名青少年患者中用于将后牙整体前移至侧切牙间隙的应用。经过30个月的治疗,患者的咬合和美观得到显著改善,并获得了理想的覆盖和覆合。治疗完成后6个月的随访记录显示结果稳定。
