This study examined orthodontic treatment strategies for patients in the mixed dentition phase, with a focus on the advantages and limitations of clear aligners and traditional fixed appliances in addressing complex tooth movements. Herein, three cases were reported to illustrate the complementary strengths of these treatment modalities. In Case 1, presurgical orthodontics for a patient with a cleft lip and palate was performed using clear aligners, resulting in successful rotation correction and optimal alignment. In Case 2, a noninvasive approach involving a transpalatal arch and fixed appliances was used to manage a high labially impacted central incisor without the use of temporary anchorage devices (TADs). In Case 3, a combination of clear aligners and braces were used to resolve severe crowding and an impacted canine, achieving the desired outcomes without extractions. The findings underscore the ability of clear aligners to enhance oral hygiene and enable precise tooth movement through software simulations. The integration of clear aligners and fixed appliances demonstrated improved treatment efficiency and patient comfort. Additional clinical trials are warranted to refine rotation correction techniques and evaluate the efficacy of TAD-assisted traction for impacted teeth.
本研究探讨了混合牙列期患者的正畸治疗策略,重点关注了透明矫治器和传统固定矫治器在解决复杂牙齿移动方面的优缺点。在此,报告了三例病例以说明这些治疗方式的互补优势。病例1中,使用透明矫治器对一名唇腭裂患者进行术前正畸治疗,成功实现了牙齿旋转矫正和最佳排列。病例2中,采用了一种涉及跨腭弓和固定矫治器的非侵入性方法来处理一颗高位唇侧阻生中切牙,未使用临时支抗装置(TADs)。病例3中,联合使用透明矫治器和 braces 来解决严重拥挤和一颗阻生尖牙的问题,在未拔牙的情况下达到了预期效果。研究结果强调了透明矫治器通过软件模拟增强口腔卫生和实现精确牙齿移动的能力。透明矫治器与固定矫治器的结合提高了治疗效率并提升了患者舒适度。有必要进行更多临床试验以完善牙齿旋转矫正技术,并评估 TAD 辅助牵引对阻生牙的疗效。
