A successful combination of conflicting approaches to diastema closure--a case report.

The closure of anterior maxillary diastemas can be accomplished in several ways. A case is reported where treatment initially consisted of the provision of porcelain laminate veneer restorations, with an unsatisfactory result. Subsequently, the restorations were reduced drastically in width and reshaped. The tooth widths were calculated from tables of mean measurements. The spaces were closed by orthodontic treatment and the original restorations were retained, saving the patient considerable treatment.
