The rotational path of insertion concept for removable partial dentures (RPDs) can be used in esthetically demanding situations. This clinical report describes the treatment of a patient with an anterior maxillary edentulous area using a rotational path RPD. To optimally improve gingival esthetics and to allow proximal retention on the surveyors, a crown-lengthening surgical procedure was performed prior to prosthetic treatment on all teeth involved in this rehabilitation. When correctly planned and fabricated, this prosthesis allows excellent functional and esthetic results, minimizes tooth preparation, and reduces the tendency toward plaque accumulation.
可摘局部义齿（RPD）的旋转就位道概念可用于对美观要求较高的情况。本临床报告描述了一名上颌前部无牙区患者采用旋转就位道RPD的治疗过程。为了最佳地改善牙龈美观并在观测仪上实现邻面固位，在修复治疗前对该修复涉及的所有牙齿进行了冠延长手术。如果设计和制作得当，这种修复体可获得出色的功能和美观效果，最大限度地减少牙体预备，并降低菌斑积聚的倾向。
