Precision and prosthetic diagnosis in esthetic anterior restoration using Digital Smile Design: A case report

Abstract

Digital Smile Design (DSD) is a tool used during the planning of esthetic restorative treatments. The aim of this clinical report was to describe a protocol that incorporates new technologies in prosthetic diagnosis, using DSD together with digital impression (3D intraoral scanner) of oral tissues, which outlines the necessary considerations to achieve a successful anterior sector restoration in biomechanical, functional and esthetic terms. A case of a 52-year-old female patient is presented, who had defective restorations with open margins in teeth 1-1 and 2-1, with functional and esthetic involvement, thus a proposed approach was the use of DSD for planning and fabrication of feldspathic ceramic crowns in CAD CAM block. Therefore, through the application of knowledge of esthetic parameters and the use of DSD, the patient was able to improve her smile, satisfying her esthetic and functional needs. The use of DSD allows virtual visualization of the results of a dental treatment before performing esthetic restorative procedures. It also improves the precision of the treatment by showing a sample of the prototype of the final restoration that the patient can approve or not, considering the esthetic and functional characteristics of the oral rehabilitation.
