Direct class IV restoration: technical report

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, the resins of choice were DA3, BA3, EA2 e CT all from Z350 - 3M, as each contains different chromas. Today for restorations on teeth older than 3M it is the good 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. The stratification with composite resin favors the naturalness so desired by the patient, because the invisibility of the restoration is achieved, leaving the smile more harmonious and beautiful, which certainly improves self-esteem.With the evolution of adhesive dentistry, it is possible to perform aesthetic procedures with greater longevity and naturalness already mentioned.
