This case report details reconstruction of a severely atrophic pre‑maxilla using rhBMP‑2 and a titanium mesh framework. Surgical technique, graft outcomes, and implant rehabilitation are described, with notes on indications and complications.
For the edentulous patient, dental implant therapy is the accepted treatment to replace one or more missing teeth as implant survival rates are greater than 90%. Unfortunately, surgical removal of dental implants occurs for a variety of reasons. As human studies are limited, this case report provides an opportunity to evaluate the peri-implant characteristics in a dental implant removed from a patient using histology. In our patient, the implant was removed three years after completion of the prosthetic phase due to fracture of the abutment that could not be removed from the implant. Histological examination of the implant revealed mature lamellar bone in direct contact with the implant surface. Histomorphometric evaluation revealed a bone-to-implant contact (BIC) of 73.6%.
Edentulism is considered a poor health outcome and may compromise quality of life. Implant-supported overdentures provide a good opportunity for dentists to improve the quality of life and oral health. Atrophic mandible poses a significant challenge to successful oral rehabilitation with dental implants. The aim of this case report is to demonstrate the concept of immediate functional loading in the mandible using unsplinted implants to support a locator attachment supported overdenture.
