Rotational path removable partial mandibular resection prostheses: A case series of patients with mandibular symphyseal defects

Abstract

Rotational path removable partial mandibular resection prostheses (MRPs) offer advantages in the management of patients with acquired symphyseal defects of the mandible, including enhanced esthetics achieved through a reduced number of clasps, the provision of rigid retainers less prone to distortion compared with flexible alternatives, and the ability to engage prominent proximal undercuts in patients lacking buccal undercuts. Additionally, removable partial MRPs represent a suitable treatment option in scenarios where the cost of implant-retained prostheses is prohibitive or in patients where implant therapy is contraindicated, such as those with a history of head and neck radiation. While the use of rotational path removable prostheses has been well documented in conventional prosthodontics, its application in maxillofacial prosthetics remains less explored. This case series describes 3 patients, all of whom underwent mandibular resections involving the mandibular symphysis and subsequently received prosthetic rehabilitation incorporating rotational path removable partial MRPs.
