Abstract

The loss of occlusal vertical dimension due to multiple tooth loss and wear can lead to a collapsed occlusion, resulting in both functional and aesthetic problems. This case report describes a patient exhibiting mandibular prognathism as a result of vertical dimension loss. A comprehensive oral rehabilitation involving an increase in vertical dimension was required. A minimal number of implants were placed, and implant-supported surveyed crowns were fabricated, allowing for the design of a stable and retentive implant-assisted removable partial denture. The treatment resulted in both functional and aesthetic improvements. The anterior rotational pattern of the mandible was alleviated, and the implant-assisted partial denture provided clinically high levels of patient satisfaction. This case report details the diagnostic and therapeutic processes involved in this treatment.
