Full Mouth Rehabilitation of a Patient with Bruxism using Implant and Tooth-supported Monolithic Zirconia with Feldspathic Veneers

Abstract

Complete oral rehabilitation in patients with bruxism is often challenging as a result of the loss of tooth structure and loss of occlusal vertical dimension. This case describes the management of a 70 year old man with a history of bruxism and excessive wear, loss of the occlusal vertical dimension, limited space for restoration, esthetic complaints and compromised dental function due to reduced tooth structure. A multidisciplinary approach was applied with tooth and implant-supported full-ceramic restorations. The patient used two full arch provisional bridges during the osseointegration of the dental implants. Maxillary and mandibular teeth and implants were restored with monolithic zirconia crowns with feldspathic veneers. An occlusion mouth guard was given to protect the restorations. After 36 months of function, no major complications were registered. The restoration of worn dentition in cases of bruxism requires proper planning and a multidisciplinary approach in order to ensure the prognosis and the success of prosthetic treatment. Partially veneered monolithic zirconia appears to be a reliable treatment option with satisfactory clinical results and minimal technical complications.
