THE USE OF LITHIUM DISILICATE CERAMIC IN SMILE AESTHETICS REPAIR - CLINICAL CASE REPORT

Abstract

The search for aesthetics in order to have a harmonious smile has led patients to seek out a dental surgeon in order to optimize their smile with the use of ceramic laminates. The aim of this paper is to present a clinical case of aesthetic oral rehabilitation in the upper region, with dental contact lens-type ceramic laminates, presenting a clinical sequence and a restorative protocol with minimally invasive preparations. Patient, A. O. J. V., male, 28 years old, presented with the main complaint of dissatisfaction with the disharmony of his smile due to diastemas and differences in the size and positioning of his teeth. The following therapeutic options were proposed: ceramic fragment, composite resin veneers or ceramic veneers. Considering the aesthetic result, color stability and durability, the patient opted for contact lens-type ceramic laminates on 10 elements (15 to 25). The following clinical maneuvers were carried out: diagnostic wax-up, root coverage surgery using the semilunar flap technique, tooth preparation using wear guides, molding with addition silicon, testing and cementing the contact lenses, finishing and polishing the interfaces and occlusal adjustment. The contact lenses in the minimally invasive technique allowed for less wear on the tooth structure, adequate adhesion to the enamel and excellent esthetic and mechanical results. The aid of wear guides during tooth preparation was essential in this type of technique.
