Abstract: The management of tooth wear, especially attrition has become a subject of interest in the Prosthodontic literature, both from a preventive and a restorative point of view. The rationales for altering vertical dimension include aesthetic, correcting occlusal relationship, and allowing space for restorations for prosthetic convenience. A critical aspect for a severely attrited teeth by full mouth rehabilitation is to determine the occlusal vertical dimension (OVD) and the inter-occlusal rest space (IRS). There is great apprehension involved in reconstructing debilitated dentition due to widely divergent views concerning the choice of an appropriate occlusal scheme for successful full mouth rehabilitation. A systematic approach for managing tooth wear can lead to a predictable and favorable prognosis. This case report highlights the stages for rehabilitation, from diagnosis to final treatment and followup for a patient with severe tooth wear. The full mouth rehabilitation procedure includes increasing the vertical dimension according to Pan-key-Mann Schuyler (PMS) philosophy followed by restoration of missing and attrited teeth with metal ceramic restorations and a removable cast partial denture (CPD).
