Bone Ring Technique: The use of autologous or allogenic bone for simultaneous augmentation and implant placement. The webinar discusses the (dis)advantage of both materials through histological evaluations and new clinical studies.
Bone Ring Technique was originally described as a one-stage procedure for vertical augmentation, in which an autogenous block bone graft is stabilized with a simultaneously inserted dental implant. Harvesting of bone from symphysis using a trephine appears to be safe and results in minimal morbidity. Autogenous bone used in Bone Ring Technique is accompanied by the fracture risk during removal or implant placement and usual donor site morbidities. The allogenic bone ring is a pre-fabricated graft which allows bone augmentation and implant placement in a one-stage procedure. The main benefit of allogenic bone ring is the avoidance of harvesting of autogenous bone. However there is not enough data in the literature about the success of this graft material. The webinar will address the remodeling process of autogenous and allograft bone rings based on histological evaluations and histomorphometric analysis in an experimental animal model. In addition, the use of autogenous and allograft bone rings in vertical alveolar augmentation and sinus augmentation will be discussed in clinical cases.
