Advances in diastema closure and tooth shape change using direct composite restorations: the Front Wing Technique.

Closing a diastema with a direct composite restoration still represents a real challenge for clinicians, mainly due to the need to create a correct contact point and emergence profile at the cervical level. The present article describes a novel anterior direct composite restoration technique for closing diastemata and changing tooth shape. The proposed technique, called the Front Wing Technique (FWT), does away with the use of the traditional wax-up and silicone index-based procedures. To date, there has been no effective way to transfer the anatomy modeled in the wax to the interproximal cervical area of anterior restorations every time these areas need to be corrected or restored. Therefore, the FWT provides a new approach to freehand model the emergence profile without gap formation. The cases in this article demonstrate the closure of maxillary and mandibular incisal diastemata, with the rationale behind each clinical step of the FWT described. This technique should be considered an alternative approach for the direct composite restoration of anterior teeth, saving chair time and cost.
