Bone grafting materials are used in dental implant procedures to address many implant-related challenges—especially in cases where the amount of bone around the implant is limited or insufficient to cover the entire implant surface. This is commonly seen in immediate implant placement (directly after extraction), where the conical shape of the extraction socket often fails to provide complete bony support around the implant. It can also occur in staged implant placement, where bone augmentation is needed to cover the implant surface on the buccal or lingual side.
For this reason, guided bone regeneration (GBR) with barrier membranes has often been used alongside grafting materials due to its physicochemical properties, aiming to achieve a bone-healing approach that is closer to natural regeneration. However, several challenges have emerged with this method, including difficulty in flap closure when a large graft volume is placed and covered with a membrane, lack of stability of many graft materials despite membrane use under intraoral functional pressures, and the difficulty of monitoring the graft site. In addition, the overall cost increases due to the combined use of a graft and a membrane.
