About Bone Grafting for Implants by Vancouver BC Specialist
What is Bone Grafting?
With bone grafting, we now have the opportunity to not only replace bone where it is missing, but also the ability to promote new bone growth. Over a period of time, the jawbone associated with missing teeth atrophies or is reabsorbed. This often leaves a condition in which there is poor quality and quantity of bone suitable for placement of dental implants. In these situations, most patients are not candidates for placement of dental implants. With bone grafting, we now have the opportunity to not only replace bone where it is missing, but also the ability to promote new bone growth in that location. This not only gives us the opportunity to place implants of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.
Types of Bone Grafts for Implants in Vancouver BC
Autogenous Bone Graft
Autogenous bone grafts, also known as autografts, are made from your own bone, taken from somewhere else in the body. The bone is typically harvested from the mandible or chin. Autogenous bone grafts are advantageous in that the graft material is live bone, meaning it contains living cellular elements that enhance bone growth.
Allogenic bone, or allograft, is dead bone harvested from a cadaver, then processed using a freeze-dry method to extract the water via a vacuum. Unlike autogenous bone, allogenic bone cannot produce new bone on it’s own. Rather, it serves as a framework or scaffold over which bone from the surrounding bony walls can grow to fill the defect or void.
Xenogenic bone is derived from non-living bone of another species, usually a cow. The bone is processed at very high temperatures to avoid the potential for immune rejection and contamination. Like allogenic grafts, xenogenic grafts serve as a framework for bone from the surrounding area to grow and fill the void.
Both allogenic and xenogenic bone grafting are advantageous in that they do not require a second procedure to harvest your own bone, as with autografts. However, because these options lack autograft’s bone-forming properties, bone regeneration may take longer than with autografts, with a less predictable outcome.
Bone Graft Substitutes
As a substitute to using real bone, many synthetic materials are available as a safe and proven alternative, including:
Demineralized Bone Matrix (DBM)/Demineralized Freeze-Dried Bone Allograft (DFDBA):
This product is processed allograft bone, containing collagen, proteins, and growth factors that are extracted from the allograft bone. It is available in the form of powder, putty, chips, or as a gel that can be injected through a syringe.
Graft composites consist of other bone graft materials and growth factors to achieve the benefits of a variety of substances. Some combinations may include: collagen/ceramic composite, which closely resembles the composition of natural bone, DBM combined with bone marrow cells, which aid in the growth of new bone, or a collagen/ceramic/autograft composite.
Bone Morphogenic Proteins:
Bone morphogenetic proteins (BMPs) are proteins naturally produced in the body that promote and regulate bone formation and healing.
Synthetic materials also have the advantage of not requiring a second procedure to harvest bone, reducing risk and pain. Each bone grafting option has its own risks and benefits. Dr. Noroozi will determine which type of bone graft material is right for you.
Straumann® AlloGraft Ring Vancouver BC
Processed human allogenic bone ring
A prefabricated ring of processed allogenic donor bone that is placed press-fit into a trephine drill-prepared ring bed. This is an innovative solution for 3-dimensional vertical augmentation of bone defects allowing a single-stage graft and implant placement. The simultaneous implant placement saves you and your patient time and a surgical step compared to a conventional bone block, reducing chair time compared to a bone block, eliminating the need for a second harvesting site and shorter time-to-teeth. Dr. Noroozi is one of very few implant surgeons in North America who has been trained formally by Dr. Giesenhagen from Germany to perform this advanced procedure.
