Introduction
Implant treatment is often accompanied by bone augmentation procedures. In addition to guided bone regeneration (GBR), the most common techniques used to expand bone volume and height of the alveolar ridge are distraction osteogenesis, bone splitting as well as apposition and onlay osteoplasty. Harvesting autologous bone blocks for vertical augmentation is a very complex and invasive procedure. The author therefore developed the bone ring technique using autologous bone and unveiled his concept in 2003. The technique with allogenic bone (maxgraft
bonering by botiss biomaterials) was further developed in collaboration with Dr. Orcan Yüksel and presented in 2010. When using this allogenic bone ring technique, treatment for the patient is optimized as the extra surgical stage and risks involved with harvesting autologous bone at a second site, can be avoided. The author has now performed almost one thousand augmentations with autogenous bone harvested intraorally and over two hundred augmentations with maxgraft
allograft bonering.
