The need to perform restorations with a natural appearance is one of the most challenging aspects of Dentistry, as well as the reproduction of the color of natural teeth in restorations is a clinical challenge, due to the complex optical characteristics of dentition Natural. As use of ceramics the need to use more opaque restorative materials or in different thicknesses, there is a great difficulty in obtaining adequate results in relation to the final color of the restoration. The objective of this work is to report a clinical case of smile rehabilitation in the anterior region with facets made of lithium dissilicate using the double cementation protocol, aiming at the final uniformization of color, and showing the advantages of use of this protocol in obtaining the aesthetics of the smile. A 47-year- old female patient with Diabetes Melitus, with main complaint the aesthetics of anterosuperior teeth, diagnosed in a pure ceramic crown in tooth 21 and a resin facet in tooth 11. With this, a planning was carried out to exchange these restorations and correction of the gingival margin of element 11, because the elements in question were different zeniths. The double cementation protocol allows a better aesthetic integration of restorations, besides allowing a reduction in the number of parts corrections by the laboratory, the preparation of facets simultaneously, ensuring a color and appropriate shape. Therefore, given the diversity of cementing agents in the dental market, it is important that the dentist has extensive scientific knowledge to know which cement to use in each prosthetic restoration, in addition to practical knowledge to know which technique to use and obtain a satisfactory result approved by the patient.
