Abstract:
In general cases, tooth wear often requires no treatment, but severe wear exceeding physiological limits can lead to permanent occlusal disharmony and necessitate comprehensive restorative intervention. Patients with non-functional mandibular movements, such as bruxism, are at greater risk of early failure of restorations making careful management essential. In this case, a 50-year-old male patient with a history of severe nocturnal bruxism presented with significant tooth wear and an unstable maxillomandibular relationship, and after centric relation guidance and diagnostic wax-up evaluation, full-mouth rehabilitation was performed. To restore the morphology of the worn teeth and reposition the displaced mandible to a centric relation, the patient had 12 weeks of provisional restoration usage and successfully adapted to the altered vertical dimension and maxillomandibular relationship before the final prostheses were fabricated. The functionally generated path (FGP) technique was used to create metal occlusal surfaces for the upper posterior teeth, ensuring precise group function during eccentric movements and preventing further failure. The patient experienced improved comfort, function, and aesthetics, with stable occlusion and no complications during the 4-month follow-up period. Regular follow-up and protective measures, such as night guards, are recommended to ensure long-term success.
