Full mouth rehabilitation of the patient with severely worn dentition and limited vertical dimension

Severely worn dentition causes various complications such as loss of tooth struc-ture, discoloration, pulp complications and loss of function and aesthetics. In this case, the patient showed particularly severe attrition in the anterior teeth and lack of space for restoration. The amount of vertical dimension was determined based on the diagnostic wax up, and the patient’s adaptation was evaluated by using a removable occlusal splint for 6 weeks. Thereafter, the coordination of the muscu-lar nervous system, aesthetics, temporomandibular joint were re-evaluated for 3 months by restoring the fixed provisional restoration. Through the above treatment process, the final restoration was completed with full mouth fixed prosthe-sis using monolithic zirconia, and functionally and aesthetically stable results were obtained.
