[Borderline cases in implantology. Extensive bone augmentation and implants in extremely atrophied upper jaw: two case reports].
The placement of implants in the vertically and horizontally resorbed maxilla for a fixed prosthodontic reconstruction still presents a challenge to the therapist. To enable acceptable implant placement and positioning, optimizing the residual bone is necessary. A new method for the reconstruction of the extremely atrophied maxilla is presented in two edentulous patients. This extensive osseous augmentation (GBR) was performed using bilateral sinus grafts, simultaneous ridge splitting and guided bone regeneration with bone harvested from intraoral sites and bone replacement material. In both patients, the osseous reconstruction of the residual ridge allowed the placement of implants for a fixed bridge reconstruction.
