Rehabilitation of a patient with moderate attrition after restoring his vertical dimension is a complex procedure. Therefore, the vertical dimension should be assessed in such a case. This clinical report describes the full-mouth rehabilitation of an elderly patient who was clinically monitored for 30 months to evaluate his adaptation to a removable occlusal splint to restore his vertical dimension. Provisional restorations were then cemented to evaluate the aesthetic and functional outcome to the new occlusion for a time period. Metal ceramic prostheses were cemented. The patient’s tolerance to changes in the existing occlusion was confirmed before proceeding to the next steps. During follow-up visits, the patient’s family reported a marked improvement in his facial appearance, dental aesthetics, speech articulation, and social life.
