ORAL REHABILITATION THROUGH THREE-DIMENSIONAL DIGITAL PLANNING: LITERATURE REVIEW AND CLINICAL CASE REPORT

Abstract

Objective: To review the literature and to report the clinical treatment on the effectiveness of oral prosthetic rehabilitation using lithium glass ceramic disilicate material IPS E.max Press and IPS E.max CAD, through planning with Digital Design Smile (DSD), and preparation by the CAD/CAM system. Literature review and case report: Glass ceramic is a material that resembles the characteristics of dental tissue and has the best optical properties among prosthetic materials. DSD makes it possible to plan for a better aesthetic result from a facial point of view, as it allows a complete workflow, representing a resource to aid in diagnosis, treatment plan and communication with the patient and laboratory technician. A patient with extensive composite resin restorations with unsatisfactory aesthetics in the anterior teeth was selected. From scanning the patient's mouth, the DSD protocol was performed and with the aid of a donor smile it was possible to determine the shape and texture of the new ceramic restorations made with IPS E. max CAD. Final considerations: Lithium disilicate glass ceramic exhibits minimally invasive rehabilitative potential and excellent aesthetic requirements. The clinical case of this study demonstrated the predictability that can be achieved with the DSD protocol. In addition, with CAD / CAM fabrication, the restorations imposed as a model for the patient followed the initial aesthetic plan.
