The aesthetic challenges of single tooth replacement: a comparison of treatment alternatives.

Several options are currently available to address the challenge of restoring a single tooth in the maxillary anterior region. To select the most appropriate treatment option for each patient, every case should be evaluated individually and all available options reviewed. The learning objective of this article is to review the treatment options and the selection of appropriate treatment modalities. The soft tissue contour around pontics and implants is discussed for efficiency, predictability, and aesthetic excellence. Three clinical cases illustrate and document three different treatment modalities in the maxillary anterior region--a single tooth implant-supported restoration, combined with porcelain laminate veneers; an adhesive bridge, combined with a porcelain laminate veneer; and a conventional porcelain-fused-to-metal bridge.
