Treatment of edentulous regions through dental implants is getting harder depending on bone resorption that arises on alveolar bone, after the removal of serious periodontal defected tooth. A wide selection of methods are applied with the purpose of bone augmentation for implant treatment. A 6-month-period of recovery is needed for bone and graft substitution after the process of bone reconstruction used when there is insufficiency of vertical and/or horizontal ridge. Called ring method, ridge augmentation and implant placement in one session reduces treatment period and the number of surgery.


Implant procedure in routine practice and autogenous block bone grafts are applied for alveolar ridge reconstruction in wide threedimensional bone defects in edentulous spaces. Taken from intraoral or extra-oral donor sites, autogenous block bone grafts might be free cancellous or corticocancellous. Autogenous grafts contain a variety of living cells and growth factors that have osteoinductive, osteoconductive and osteogenic effects [1-3].

The remaining bone morphology is vital to implant placement on aesthetic region. After advanced periodontitis, serious bone resorption might be seen around the teeth, which consequently makes implant placement difficult on these regions following tooth extraction. Before implant placement, bone augmentation procedures are routinely needed, so the horizontal and vertical extent of the defect plays a vital role in the use of the bone augmentation applied to reconstruction of these ridge defects [5]. Taken from the symphysis, block bone grafts can be applied for predictable bone augmentation which is up to 6 mm in horizontal and vertical dimensions [6,7].

It is possible for the surgeon to augment the bone and insert the implant in one session using the bone ring transplantation procedure developed by Bernhard Giesenhagen in 2004 [4,5].

The fact that autogenous block bone grafts have osteoinductive, osteoconductive and volume enhancement properties makes them ideal for the reconstruction of three-dimensional alveolar bone defects. Bone integration, however, requires at least a three-month recovery period after osseous reconstruction. On the one hand, it can be said that the treatment period is raised by a second operation and recovery period when dental implants are taken into consideration. On the other, treatment period and the number of operations is shortened by “ring technique” which is used as single stage crest augmentation with simultaneous implant placement [8].

Using not only early implant placement but autogenous bone graft in the same time along with graft in the shape of “bone ring” taken from the symphysis, this article gives a definition to a surgical technique of restoring maxillary lateral region.


In the clinical examination of the 45-year-old male patient, who had gingival recession on the maxillary right lateral, who was systematically healthy and did not smoke, the second degree of gingival recession in the buccal region and vertical and horizontal mobility on that tooth was diagnosed (Figure 1). When radiographically examined, vertical and horizontal bone loss around the tooth was seen (Figure 2), so the removal of the teeth and the placement of ring shaped bone graft harvested from symphysis region with passive intra-bone implant on defect region after the healing of soft tissue were decided to perform.
