Retrofitting a tooth-supported crown with an implant and abutment: a clinical report

This article presents a treatment option for a fractured maxillary central incisor root as part of an existing complete maxillary rehabilitation. After the root extraction and immediate implant placement into the extraction socket, an acrylic resin removable partial denture (RPD) was placed. Six months later, a screw-retained provisional restoration was placed to guide the development of soft tissue contours. An impression was made, and a custom abutment was fabricated to conform to the new gingival profile and the intaglio surface of the existing metal ceramic crown. The custom abutment was placed and the preexisting metal ceramic crown was then cemented.
