In this paper orthodontic treatment involving extraction of a lower incisor is described. This has traditionally been regarded as a compromise as loss of a lower incisor renders it impossible to achieve true ideal occlusion. However, with careful case selection, treatment planning and visualization of the post-treatment occlusion, excellent functional and aesthetic results can be achieved. The various factors that govern the decision to treat certain malocclusions in this way are discussed and a clinical case is presented to demonstrate this type of treatment.
本文描述了涉及拔除一颗下切牙的正畸治疗。传统上，这被视为一种折衷方案，因为拔除一颗下切牙使得无法实现真正理想的咬合。然而，通过仔细的病例选择、治疗计划以及对治疗后咬合的可视化分析，可以取得优异的功能和美学效果。本文讨论了决定采用这种方式治疗某些错牙合畸形的各种因素，并展示了一个临床病例以说明此类治疗。
