Rehabilitation of masticatory ability in patients with reduced periodontal tissue support is a multiple challenge in dentistry. It has been shown that tooth mobility is reduced by a splint in place. Splints may be constructed of various materials. Development of fiber-reinforced composite materials offers a new and conservative approach for tooth replacement and stabilization. This case report describes the rehabilitation and 2-year follow-up of a patient with advanced periodontal problems by using a glass fiber-reinforced composite resin material.
