Patients with dentoalveolar asymmetries can present some of the most biomechanically challenging situations to the orthodontist. One creative approach for managing dental asymmetries is to extract a combination of teeth that will simplify intra-arch and interarch mechanics. Often this will also reduce the dependency on patient compliance for elastic wear and may even shorten treatment time. Atypical extraction patterns can also be beneficial in the presurgical orthodontic preparation of orthognathic surgery patients. Multiple diagnostic scenarios are discussed, and various treatment plans involving asymmetric extraction patterns are reviewed.
牙牙槽不对称的患者可能会给正畸医生带来一些生物力学上最具挑战性的情况。一种处理牙齿不对称的创新方法是拔除一组牙齿，这将简化牙弓内和牙弓间的力学关系。通常，这还会减少对患者配合佩戴弹力装置的依赖，甚至可能缩短治疗时间。非典型拔牙模式在正颌手术患者的术前正畸准备中也可能有益。文中讨论了多种诊断方案，并回顾了涉及不对称拔牙模式的各种治疗计划。
