Abstract:
Objective To evaluate the clinical effects of the bone-ring augmentation in implant restoration using the bone ring technique.Methods Sixteen patients (30 teeth) with severe alveolar bone absorption were selected.Bone rings (circular osteotomies) were outlined at the symphysis area and a central osteotomy for implant placement was done using the bone ring drills before its removal.The rings were then removed and sculptured to fit the alveolar ridge and then covered by Bio-oss and Bio-Gide membrane.This was followed by screwing the implant through the ring,gaining its primary stability from the prepared basal bone.After 4-6 months,the implant was exposed and abutment connected for temporary restoration.Results Of the 16 patients,14 cases were healed by first intention,2 cases were infected after the bone ring implantation resulting in some bone absorption but healed after bone grafting materials were placed at the second stage of the onlay procedure.The bone ring implantation showed no absorption and no implant failure.After the bone grafting the alveolar bone height increased by 4.1 mm on average and the thickness increased by 3.27 mm on average.Conclusions Implant bone ring can effectively augment the absorbed alveolar ridge.The procedure has the advantages of bone removal,grafting and implantation at one stage.
