Abstract

Abstract: Objective: To present a challenging case of occlusal reconstruction assisted by digital technology in a patient with cleft lip and palate under the guidance of six-stage principle. Diagnosis and treatment: The diagnosis and treatment plan were confirmed following a comprehensive examination. The vertical dimension was adjusted using a maxillary full dentition stable occlusal plate. First of all, polymethyl methacrylate prosthesis was fabricated for temporary repair. Then, the formal restorations were designed by replicating the surface morphology of the temporary prosthesis after physiological abrasion and adaptation, and then were made with monolithic zirconia. In the end, a removable partial denture was fabricated to achieve aesthetic and functional reconstruction. Results: After restoration, the patient demonstrated a satisfactory occlusal relationship, along with an improvement in the upper lip’s fullness. Upon one-year follow-up, the patient’s occlusal function and periodontal status remained stable. Conclusions: The application of the six-stage principle and digital technology facilitated the safe and personalized promotion of occlusal reconstruction in clinical setting.
