Teeth Wear With Dentin Hypersensitivity Restored By Ceremic Occlusal Veneers

In this study, occlusal ceramic veneers were used to restore posterior teeth with severe wear and dentin hypersensitivity. A 3 to 4 years follow-up was conducted to observe the clinical outcomes. Twelve patients were selected according to the inclusion criteria, and a total of 23 occlusal veneers were fabricated. Radiovisiography were used to observe the thickness of the dentin at the pulp chamber roof, and occlusal tooth preparation was carried out to obtain a restoration space of approximately 1 mm for the occlusal veneers. Immediate dentin sealing was performed using a dentin adhesive. Impressions were taken, and the occlusal veneers were fabricated and cemented. Examinations were conducted on the day of cementation, 3 - 6 months after cementation, and annually. A 3 to 4 year follow - up evaluation was carried out using the modified FDI evaluation criteria. Three occlusal veneers fell off approximately six months after surgery, and another occlusal veneer fell off nearly four years after surgery. The remaining occlusal veneers are currently intact. The dentin hypersensitivity symptoms of only one patient disappeared six months after surgery, while those of the remaining patients disappeared immediately after restoration. It suggests that occlusal veneers can be used to treat dentin hypersensitivity symptoms in severe teeth wear.
