摘要
本病例报告描述了使用上颌骨骼扩张器(MSE)矫正上颌缩窄的病例,患者是一名 15 岁的女性,骨骼形态为 III 级,且牙齿不对称。该上颌骨扩张器带有四个微型种植体,用于矫正上颌骨缩窄、后牙双侧交叉咬合和牙列拥挤。治疗前后的锥形束计算机断层扫描对比显示,大部分上颌骨扩张是矫形性的,牙槽骨弯曲和牙齿倾倒的情况极少。固定矫治器被用来矫正牙齿拥挤和错颌畸形。使用 MSE 非手术疗法获得了稳定和令人满意的上颌骨扩张效果。
A skeletal Class III young adult with severe maxillary transverse deficiency treated with maxillary skeletal expander.
This case report describes correction of maxillary constriction using a maxillary skeletal expander (MSE) in a 15-year-old female with a skeletal Class III pattern and asymmetry. The maxillary expansion device with four mini-implants was used to correct the constricted maxilla, bilateral crossbite of the posterior teeth, and crowding of the dentition. Comparison of cone-beam computed tomography scans before and after treatment showed that the majority of maxillary expansion was orthopedic, with minimal alveolar bone bending and tooth tipping. Fixed appliances were used to correct the crowding and malocclusion. Stable and satisfactory maxillary expansion was obtained by using MSE non-urgically.
