上颌双侧第二磨牙不同拔牙位点保存及两种种植体系统修复效果观察(附1例6年随访报告)

Evaluation of implants placed in ridge preserved bilateral maxillary second molars with flap versus flapless procedures:a case report with a 6-year post-loading follow-up

磨牙是牙周炎的好发牙位,罹患重度牙周病变无保存价值的磨牙常存在广泛的牙槽骨破坏。拔牙位点保存可维持良好的牙槽嵴软硬组织轮廓,为种植治疗提供有利条件。本文完整展示了1例双侧上颌第二磨牙在拔牙同期分别采用不同方法行拔牙位点保存后进行种植修复,并完成为期最长6年随访的全过程,为存在严重牙槽骨破坏的上颌第二磨牙临床决策提供了一定参考。

Molar sites with advanced periodontitis often caused severe bone loss.Maxillary second molar lies in the distal area of the maxillary arch,where oral hygiene is difficult to perform and implant treatments has higher risk.Ridge preservation is performed after tooth extraction to facilitate implant placement by maintaining hard and soft tissue contour.This article presents a case with bilateral maxillary second molars receiving different methods of ridge preservation prior to implant reconstruction at 6 years of function,which provides evidence and clinical experience for the treatment plan and management for such kind of cases.
