Conventional devices used for surgically assisted rapid palatal expansion are tooth-borne. Dental fixation entails a number of possible drawbacks such as loss of anchorage, skeletal relapse during and after the expansion period, cortical fenestration and buccal root resorption. A bone-borne titanium device with interchangeable expansion modules, used with a callous distraction policy, is presented.
用于外科辅助快速腭扩展的传统装置是牙支持式的。牙齿固定存在许多可能的缺点，如支抗丧失、扩展期及扩展后骨骼复发、皮质开窗和颊侧牙根吸收。本文介绍了一种带有可互换扩展模块的骨支持式钛制装置，采用骨痂牵张策略使用。
