Prosthetic approach to tooth structure damage associated with dietary habits and bruxism: A case report

Introduction: Tooth structure loss resulting from parafunctional habits such as bruxism, compounded by erosive dietary factors, presents a multifactorial challenge in restorative dentistry. Patients often exhibit a combination of advanced anterior wear, dentin hypersensitivity, and non carious cervical lesions. Successful rehabilitation requires a minimally invasive, esthetically driven, and functionally stable prosthetic approach. This case presents a comprehensive adhesive and occlusal strategy for managing tooth wear caused by bothbruxism and dietary habits. Case Description: A 54-year-old female patient presented with severe anterior tooth wear, dentin hypersensitivity, and non carious cervical lesions attributed to parafunctional habits, particularly bruxism. The maxillary central incisors exhibited significant structural compromise and esthetic concerns. To fulfill the functional and esthetic needs of the patient, lithium disilicate crowns were placed on the maxillary central incisors. Additionally, seven maxillary anterior teeth were restored using minimally invasive lithium disilicate laminate veneers. A monolithic zirconia crown was placed on the maxillary first molar to reinforce posterior occlusal support. Tooth preparations followed adhesive principles, and the occlusion was carefully evaluated and adjusted. A protective occlusal splint was delivered post-treatment to eliminate future damage. Discussion: This case emphasizes the importance of early diagnosis and a comprehensive, adhesive-based prosthodontic treatment plan in managing bruxism induced tooth wear. Lithium disilicate ceramics allowed for both conservative tooth preparation and high esthetic outcomes. The use of a monolithic zirconia crown in the posterior ensured durability. The integration of occlusal assessment and an occlusal splint served as critical components for maintaining long-term stability. Conclusion: Through a customized, adhesive prosthodontic strategy, it was possible to restore esthetics, relieve sensitivity, and prevent further damage in a patient affected by bruxism.
