For horizontal bone deficiency, GBR with a bone substitute and barrier membrane is applied. However, problems such as operability of the barrier membrane and infection due to wound dehiscence have been reported.
In this case series, good bone formation was achieved without a barrier membrane by covering and fixing carbonate apatite and autogenous bone with the periosteum.
During implant placement, the full-thickness flap was carefully elevated to avoid disruption, forming an envelope without tension-relieving incisions. Following the simulation, implant placement surgery was performed. After perforating the cortical bone to ensure blood supply, the buccal space was filled with bone graft material. This consisted of calcium phosphate mixed with autogenous bone harvested during implant socket preparation and moistened with saline solution. The mixture was packed buccally to cover the implant body as a bone graft material to augment bone.
CBCT images taken more than three years after completion of implant treatment showed hard tissue-like radiopaque areas, indicating an increase in horizontal hard tissue volume.
By covering the horizontally resorbed alveolar ridge with a mixture of carbonate apatite bone substitute material and autogenous bone using the periosteum, favorable bone regeneration was achieved without the use of a barrier membrane.
