正畸治疗的目标就是要达到口颌系统功能的平衡,以及实现牙齿、颅、面型的美观和理想的咬合。Bolton于20世纪提出前牙比和全牙比的概念,并被广泛采纳和接受,成为错畸形的诊断、设计和预测错畸形治疗的一个常规指标和重要方法。Bolton指数还受很多因素的影响,但其决定因素还有待研究。 The goal of orthodontic treatment is to achieve the balance of oral mandibular system function, as well as the aesthetic and ideal occlusion of the teeth, skull and face. Bolton put forward the concept of anterior teeth ratio and total teeth ratio in the 20th century and was widely adopted and accepted as a common indicator and important method for diagnosis, design and prediction of malformation deformity treatment. Bolton index is also affected by many factors, but its determinants have yet to be studied.
