Local Ridge Augmentation Using Bone Grafts and Osseointegrated Implants in the Rehabilitation of Partial Edentulism: Preliminary Results

Henning Schliephake, MD, DDS/Friedrich W. Neukam, MD, DDS, PhD/Herbert Scheller, DDS, PhD/Klaus J. Bothe, MD, DDS

The aim of the present study was to analyze the results of local augmentations of alveolar ridge defects using bone grafting and implants (n = 55) in 16 partially edentulous patients. The mean period of functional loading was 27 months (range 2 to 80). Two implants were lost during initial healing because of wound dehiscence over the graft with subsequent infection and loosening of the implants. Two implants were left unexposed during abutment connection, so that 51 out of 55 implants placed were in function at the time of follow-up. Peri-implant parameters, such as plaque accumulation, gingival inflammation, pocket depth, and implant mobility, compared well to the results found previously with implants without bone grafts in partially edentulous jaws. Plaque accumulation was registered for 18.9% of all tested abutment surfaces, while signs of gingival inflammation were present in only 3.6%. All implants were immobile, exhibiting Periotest values between - 5 and 5. A significant change in marginal bone height around the implants (0.3 mm) was found during the period of functional loading.
