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.

Today, we have the ability to grow bone where needed. This not only gives us the opportunity to place an implant of proper length and width, it also gives us a chance to restore functionality and esthetic appearance.

Major Bone Grafting

Bone grafting can repair implant sites with inadequate bone structure due to previous extractions, gum disease, or injuries. The bone is either obtained from a tissue bank or your own bone is taken from the jaw, hip, or tibia (below the knee.) Sinus bone grafts are also performed to replace bone in the posterior upper jaw. In addition, special membranes may be utilized that dissolve under the gum and protect the bone graft and encourage bone regeneration. This is called guided bone regeneration or guided tissue regeneration.

Major bone grafts are typically performed to repair defects of the jaws. These defects may arise as a result of traumatic injuries, tumor surgery, or congenital defects. Large defects are repaired using the patient’s own bone. This bone is harvested from a number of different sites depending on the size of the defect. The skull (cranium), hip (iliac crest), and lateral knee (tibia) are common donor sites. These procedures are routinely performed in an operating room and require a hospital stay.

Types of Bone Grafts

Autogenous Bone Grafts:

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 chin, jaw, lower leg bone, hip, or the skull. Autogenous bone grafts are advantageous in that the graft material is live bone, meaning it contains living cellular elements that enhance bone growth.

However, one downside to the autograft is that it requires a second procedure to harvest bone from elsewhere in the body. Depending on your condition, a second procedure may not be in your best interest.

Allogenic Bone:

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 its 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:

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:

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 Morphogenetic 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. Your doctor will determine which type of bone graft material is right for you.

My husband was referred to Dr. Belinfante because he was having an issue with a tooth that needed to be extracted and he also needed an implant a well.. to say that his experience was pleasant would be an understatement.. his experience in his words was AWESOME!!!. He hasn't experience any pain and the next day to our surprise Dr. Belinfante himself actually called to check on him.. (sidenote: No doctor that I'm aware of let alone a surgeon has ever called his patients personally to check on them after a procedure and it was on a Saturday) so with that being said.. we are recommending our friend and family to Dr. Belinfante for all of their dental needs.. he is absolutely the best .. Thank you Dr. Belinfante for a job well done!!

I wish all Doctors were as educated and caring as Dr Wunderlle is. He doesn't rush you out, he explains everything and wants things done right from start to finish & tells you like it is.. good or bad. I appreciate that and him. I wish I had found him and his staff sooner. They are all amazing!

The staff of this location is AMAZING! I am one of those people that are terrified of anything dental (which is why I ended up here) the staff was amazing. They made me laugh and smile the entire time... even before the laughing gas. They played my Gangster Rap while I was going to sleep and the entire time they were working on me. ( I heard them telling someone that music was the previous patients request) I chuckled. Dr. Wunderle III is AMAZING! I had major work done and he did a great job. I would send any one of my friends or family to him! He also has been very patient with me as I am not an easy patient. Can't rave enough about this office and the care that they have given me.
