Abstract: Objective: Hybrid porcelain veneer technology was used for occlusal reconstruction. Methods: Through diagnosis and treatment design, the treatment process is divided into disease control stage, aesthetic and functional recovery stage and final repair stage. Results: The abnormal discharge of masticatory muscles decreased after the patient wore the stable occlusal plate; Stable and repeatable movement; The shape of the tracing curve is smooth, smooth and symmetrical. The wax shape of the anterior teeth can improve the aesthetics and guide the reconstruction function at the same time; The wax pattern of the posterior teeth restored the shape of the mandibular surface and maintained the vertical distance, and reconstructed the masticatory function.Try to wear the temporary prosthesis in the mouth, and obtain good guidance of the front teeth, coordination of the occlusal relationship of the rear teeth, and balance of bilateral masticatory muscles. In the final restoration stage, the palatal cast porcelain veneer and labial feldspathic porcelain veneer were used to form an integrated composite porcelain veneer for the restoration of anterior teeth, and the posterior teeth were repaired with cast porcelain veneer. The examination showed that the median occlusion was stable and the lateral movement was canine protection. After 1, 3, and 6 months of treatment, the oral and maxillofacial function was stable, the patient had no obvious discomfort, and the symptoms of muscle tenderness completely disappeared after treatment. Conclusion: The hybrid veneer provides a new reference for the design of anterior restorations of full-mouth rehabilitation.
