Rehabilitation of an edentulous posterior mandible to restore function and arch stability can be accomplished with a removable partial denture or an implant supported fixed partial denture. If the alveolus is severely resorbed, implant placement becomes challenging due to inadequate bone and the position of the inferior alveolar nerve. This report details a situation where a mandibular fracture occurred soon after inferior alveolar nerve (IAN) transposition and simultaneous implant placement. The prosthodontic reconstruction was completed using a fixed‐dental prosthesis.
The technique in this article was developed to provide a means to create prepared guide planes of proper dimension to ensure a more stable and retentive removable partial denture prosthesis (RPDP) framework when providing this service for a patient. Using commonly found clinical materials, a paralleling device can be fabricated from the modified diagnostic cast of the patient's dental arch requiring an RPDP. Polymethyl methacrylate or composite added to an altered thermoplastic form can be positioned intraorally and used as a guide to predictably adjust tooth structure for guide planes. Since it can potentially minimize the number of impressions and diagnostic casts made during the procedure, this can help achieve the desired result more efficiently and quickly for the patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
