Abstract

Purpose: To present a case report of a patient with amelogenesis imperfecta rehabilitated with 26 CAD-CAM all-ceramic fully sintered zirconia crowns. Case description: A male subject, 28 year-old, sought dental treatment presenting a clinical condition compatible with amelogenesis imperfecta. All teeth had yellow, brown, and white areas of weak enamel. Composite restorations were present on teeth 14, 16, 24, 25, 26, 27, and 46; dental caries were shown on teeth 36, 37, and 47. Hipersensitivity was reported. The treatment included fully sintered zirconia crowns for all teeth, using a CAD-CAM system. No problems of marginal adaptation of the crowns were detected, and the final results were satisfactory for both the patient and the clinician. Conclusion: The clinical rehabilitation of an amelogenesis imperfecta case is a challenge, and a multidisciplinary approach is required. Zirconia all-ceramics crowns are an excellent option to restore dental aesthetics as the opaque zirconia coping can mask dischromic abutments, and the crowns have biocompatibility and improved physical properties.
