title: Immediate implant-supported provisional restoration with a root-form pontic for the replacement of two adjacent anterior maxillary teeth: A clinical report.
abstract: In implant therapy, the replacement of 2 adjacent maxillary anterior teeth presents several unique challenges: mesiodistal space constraints, the need to maintain or create natural gingival esthetics, the need for esthetic provisional restorations, and the management of nonaxial forces. The treatment presented addresses these challenges through the use of an immediately placed single implant at the central incisor position with a central to lateral incisor cantilever prosthesis in both the immediate provisional and definitive restorations. The provisional restoration was designed to minimize pressure on the surgical site, optimize space for the gingival tissues, and control occlusal loading of the implant during the initial stages of osseointegration. The pontic was modified to replicate the subgingival root anatomy and enhance the gingival esthetic outcome.
