Direct composite restorations in anterior teeth. Managing symmetry in central incisors.

In direct restorations of anterior teeth, particularly central incisors, symmetry plays an important role. The clinician can take advantage of silicone indexes based on a wax-up to build palatal and incisal walls; however, when he has to reproduce free-hand chair-side symmetrical items like interproximal emergence profiles, macro- and microsurface textures, and chromatic characteristics, the result can often be unpredictable. A step-by-step class IV restoration treatment will be described, as well as a simple procedure to help reproduce, check and correct symmetrically interproximal wall contours and chromatic characteristics.
