Implant and provisional crown placement: a one stage protocol

Most endosseous implant systems are placed using a two-stage surgical procedure. The surgical stages are separated by a period of 4 to 6 months to allow osseointegration. At Stage-I surgery, the implant is fixed in bone and submerged under mucosa, while at Stage-II surgery, the implant is exposed and the transmucosal abutment is connected to the implant. The one-stage nonsubmerged surgical procedure with immediate transmucosal extension using traditional two-stage implant systems is being used to treat partial and complete edentulism. This is a case report of 10 patients treated with endosseous implants in the maxillary anterior region with immediate provisionalization using a one-stage surgical procedure. The investigators found that all patients experienced minimal discomfort from complications after the one-stage surgery and immediate placement of the provisional restoration. No signs of inflammation or mobility were observed during the first 6 months. The partially edentulous anterior maxilla can be restored to an esthetic form in a single clinic visit.
