牙槽骨厚度与正畸治疗相关性研究进展

Progress in the Relationship between the Thickness of the Alveolar Bone and Orthodontic Treatment

正畸治疗过程中牙根的移动能力和范围决定了矫治最终效果。牙齿移动量,移动方向与牙根周围牙槽骨厚度密切相关。骨量不足将大大增加骨开窗骨开裂,牙根吸收或前牙区美观欠佳,牙周组织破坏等风险。影响骨厚度的相关因素为牙位,错类型,牙槽骨高度,密度,牙周生物型等。本文对牙槽骨厚度与正畸治疗的密切联系及影响牙槽骨厚度的因素做一综述。

The final result of orthodontic treatment depends on the ability and range of root movement of teeth. The thickness of the alveolar bone is largely associated with the the distance and direction of tooth movement during the orthodontic treatment. Insufficient bone amount largely increases the risk of bony dehiscence and fenestration,root resorption or unsatisfying aesthetics of anterior region,and periodontal tissue damages.Factors related to the thickness of alveolar bone are：teeth position, type of malocclusion, periodontal biological type, and etc. This paper aims to review the relationship between alveolar bone thickness and orthodontic treatment, as well as factors influencing alveolar bone thickness.
