Abstract

A clinical report is presented that describes the restoration of a severe anterior maxillary ridge defect and pneumatized sinuses with a rotation-path partial removable dental prosthesis and implant-supported abutments. Other treatment options were considered and rejected based on patient preferences and limitations, which included avoiding invasive surgeries. The principles of integrating fixed and removable prosthesis design were applied. However, the clasp design was modified to take into account the direct bone-to-implant contact of the abutments. An esthetic and functional outcome was obtained without any overly invasive surgery.

摘要

本文呈现了一份临床报告，描述了使用旋转路径式局部可摘义齿和种植体支持基台修复严重的上颌前部牙槽嵴缺损和气化鼻窦的情况。基于患者的偏好和限制因素，考虑并排除了其他治疗方案，其中包括避免进行侵入性手术。应用了固定修复和可摘修复体设计相结合的原则。然而，对卡环设计进行了修改，以考虑基台的骨与种植体直接接触情况。在未进行任何过度侵入性手术的情况下获得了美观和功能良好的效果。
