Radiographic Assessment of Buccolingual Dimension of Allogenic Bone Ring When Used Simultaneously with Dental Implant Placement

Abstract

Purpose: This study aimed to evaluate the use of allogenic bone ring technique to restore the bucco-lingual dimension of the alveolar bone defects combined with simultaneous dental implant placement. Subjects and methods: Ten patients requiring bone augmentation horizontally or both horizontally and vertically at the time of implant placement were included in this retrospective study. All patients received simultaneous bone augmentation surgery and implant placement with allogenic bone ring grafts. Postoperative efficacy of the technique was evaluated using CBCT as a radiographical parameter. Results: Survival rates of implants were 100%. Cone-beam computed tomography revealed that the allogenic bone ring graft had significantly sufficient horizontal bone augmentation below the implant neck platform to 0 mm, 1 mm, 2 mm, and 3 mm. It could also provide an excellent peri-implant tissue condition during the 6 months’ follow-up after loading. Conclusion: The bone ring technique with allogenic bone ring graft could increase and maintain horizontal bone mass in the region of the implant neck platforms in serious horizontal bone defects.
