Esthetic Treatment of a DiffuseAmelogenesis ImperfectaUsing Pressed Lithium Disilicate and Feldspathic Ceramic Restorations: 5-Year Follow Up

Abstract OBJECTIVE: The treatment of a diffuse and severe case of amelogenesis imperfecta represents a challenge for the dental team and in particular for the dentist who perform the prosthetic restorations. CLINICAL CONSIDERATIONS: The enamel alterations, which are characteristic of the disease, determine different problems that need to be carefully planned and solved before the beginning of the treatment, with particular regard to the materials used to perform the restorations. In order to create the best conditions to perform the prosthetic restoration, the treatment plan should be multidisciplinary. In addition, the young age of the patients usually affected by the disease imposes a very conservative and cautious approach. The main goals of the therapy are represented by the need to protect the occlusal dental surfaces from the abrasion and provide a satisfactory esthetic result. In particular, dental abrasions if not treated may determine the loss of the vertical dimension as well as a diffuse and marked dentinal hypersensitivity. CONCLUSIONS: A correct treatment plan and the use of the new adhesive ceramic materials made it possible to obtain good results both from a functional and esthetic point of view with a much more conservative approach compared with the traditional one. CLINICAL SIGNIFICANCE: This clinical report describes the prosthetic rehabilitation of an adult female patient with a diffuse amelogenesis imperfecta using feldspathic ceramics for the esthetic regions and monolithic lithium disilicate material for the posterior areas.
