Results A two-year follow-up revealed there occurred butment caries,luxated butment,and overlain residual root gingivitis,even on the rise,while the alveolar ridge showed no uneven absorption.

结果基根龋、基松动、覆盖残根龈生随时间呈递增趋势,而槽嵴则无不均匀吸收。

Methods By adhering the bracket to the movable teeth and holding the butment erect or adjusting edentulous space depend on different clinical needs.

方法要移动齿上粘着托槽,根据修复要求,竖直基或扩大、减少缺间隙。
