Abstract

The objective of this work was to approach a freehand restorative technique for class IV in composite resin. The procedure was performed on a mannequin containing elements 12, 11,21 and 22, the technique was performed on element 21, the same was provided with the ready preparation, vestibular bevel, drill used with 1190 tapered diamond tip, the resins of choice were CT, dentin A3, body A3, WB and enamel A2 all from Z350 - 3M, as each contains different chromas. Today for restorations on teeth older than 3M it is the best option on the market, with the patent for nanoparticulate resins. The professional must learn the rules of aesthetics of natural teeth for the use of these materials. Treating that natural teeth are polychromatic, while composite resins are monochromatic. Given the existence of a wide variety of resins and technical possibilities, the following text proposes a clinical sequence of reconstruction of anterior teeth with compromised incisal angle due to fracture or caries. Restorative rehabilitation, in addition to promoting health, provides a favorable aesthetic appearance for the smile of the patient, thus raising the patient's self-esteem. The introduction of the acid conditioning technique and the development of adhesive systems associated with improvements in the mechanical properties of composite resins have provided new perspectives for aesthetic dentistry.
