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. This type of bone graft consistently yields an adequate quality and quantity of bone for long term dental implant health and esthetics.
The most popular reasons to require such a graft for implant placement are the following: long-standing tooth infection, a failed implant, long term tooth absence or the patient's own bone was never very thick or in other words, they were born with thin bone.
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" which will experience a healthy and long quality of life. Second, perhaps, to what mother nature provides.
Securing a solid piece of bone that best matches or is superior to the characteristics of the existing bone is the foundation of the ideal graft. The patient's own bone is the universally accepted gold standard for bone grafting.
Bone 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 hip bone is autogenous, characteristics are not as similar to bone in the oral cavity and has been known to shrink after placement due to chemical make-up and 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. At the conclusion of the surgery, the soft tissue is returned to its starting position where it predictably reattaches.
Once extracted, the harvest site is filled in with a regenerative bone product and sometimes GTR (guided tissue regeneration) membranes are used to create a very rapid regenerative process for replacing the excised bone. The bone will grow back in this area with no significant deficit and the profile of the chin does not change.
