Modified Bone Ring Tenting Technique for Alveolar Ridge Augmentation and Simultaneous Implant Placement: A Technical Note.

Alveolar ridge resorption following tooth extraction or periodontal disease often necessitates bone augmentation to restore sufficient volume for stable and esthetic implant placement. However, conventional guided bone regeneration using collagen membranes demonstrates limited space maintenance and graft stability, particularly in complex defects. Additionally, harvesting autogenous bone requires a secondary surgical site, increasing morbidity and prolonging recovery. To address these limitations, we present the modified bone ring tenting technique, which utilizes autogenous bone blocks to achieve stable bone regeneration without a secondary donor site. Ring-shaped bone grafts are placed to create a stable tent-like scaffold that preserves the regenerative space and allows for simultaneous implant placement. Preliminary evidence from a clinical case series demonstrated favorable outcomes, with postoperative cone-beam computed tomography confirming predictable bone regeneration and stable implant integration. The modified bone ring tenting technique reduces invasiveness, avoids donor-site complications, and shortens recovery time, offering a reliable and esthetically favorable solution for implant rehabilitation in the esthetic zone.
