Bone Harvesting - Chin Block Graft

WARNING - This presentation clip is extremely GRAPHIC

The characteristics of jawbone frequently "defines" what type of bone grafting procedure will produce the best results in terms of predictability and long term endurance.

In this video a male patient sustained an implant failure due to poor bone quality in the maxilla. It was determined that to augment the insufficient width and density of bone at the implant site, a solid piece of healthy bone would provide a solid foundation for recreating an "implant environment" that is second, only perhaps, to what mother nature provides.

Securing a solid piece of bone that best matches the characteristics of the existing bone and is derived from the patient (autogenous graft material) is superior to using other types of graft procedures and/or products that use a bone matrix product only, cadaver grafts and even autogenous hip bone (while autogenous, characteristics are not as similar to bone in the oral cavity - blood supply differences).

Chin block and Ramus grafts best match the density and blood supply characteristics of healthy jaw bone. For this patient a bone block is being excised from the chin area. The soft tissues along the mandible are temporarily moved to provide the best access to the harvest site.

Once extracted, the harvest site is filled in with regenerative bone product and GTR membranes which create a very rapid regenerative process for replacing the excised bone.
