Sectional porcelain veneers for a maxillary midline diastema closure: a case report.

Diastema closure is a frequently requested, technique-sensitive cosmetic procedure. There are many techniques and materials that can be employed to close diastemas. While direct composite techniques can be economical and successful, they do present challenges in achieving satisfactory clinical and esthetic results. Traditional porcelain veneer placement may offer an excellent esthetic result, but typically requires the removal of tooth structure; as such, this is an irreversible procedure. The present article reports the case of a maxillary midline diastema closure in a healthy dentition by means of sectional porcelain veneers simply cemented onto the natural teeth and without tooth preparation. A step-bystep procedure is proposed for illustrating the proper implementation of an additive-only and noninvasive indirect technique that yields a satisfactory clinical and esthetic outcome for clinician and patient.
