Objective: To evaluate the clinical effect of cosmetic restoration of ultra-thin porcelain veneer anterior teeth. METHODS: Thirty-two patients (108 teeth) with cosmetic restoration of anterior teeth due to tetracycline tooth, dental fluorosis, enamel hypoplasia, excessive interdental space, tooth defects and age-related yellowing were treated with ultrathin hot die casting Porcelain veneer for repair. At 1, 6, 12, 24, and 36 months after surgery, assessment was made according to the American Public Health Association’s Amendment Standard (USPHS). Results: After 3 years of clinical observation, there were 2 fractures in 108 porcelain veneers and the success rate of prosthesis was 98.1%. The edge coloring rate of smokers was significantly higher than that of non-smokers. CONCLUSION: The ultra-thin hot-pressed cast porcelain veneer has the advantages of less abrasive tissue removal and higher porcelain veneer restoration, which has a good clinical rehabilitative effect.
