Different Types of Bone Grafts: Can You Mix Them?


Julie asks:

I understand there are different types of bone grafting material and I've been consulting with a dentist for a bone graft. I am wondering if the dentist can mix the different types of bone graft, whether it is bovine, human or synthetic? Can you mix two of them together with or without antibiotic? I am concerned, since this is what my dentist suggested. Thanks for any advice.

Different Types of Bone Grafts: Can You Mix Them?

Answered By: Dr. Michael Tischler - Woodstock , NY


It is quite common to mix different types of bone grafting material when a graft is being performed. Different materials offer different properties to a graft. For instance cow bone as you mentioned, might be mixed with a de mineralized donor bone to add mineralization. Often a persons own bone is also mixed into a graft for growth factors.

Hope that helps,

Different Bone Graft Materials

Answered By: Dr. Theodore M. Grossman - Aventura , FL

Hi Julie
I routinely premedicate my bone graft patients with an antibiotic and keep medicating for ten days. Mixing certain graft materials allows greater potentiation of bone growth. The addition of BMP-2 (growth factor) added to a collagen sponge has great results when added to bovine graft materials.

I would agree with Dr

I would agree with Dr Tischler, but disagree with Dr Grossman. You can place other growth factors into the graft that are less expensive than what he talked about, and get just as good results. Antibiotics is also controversial, you can get great results to detoxify the site with a laser.
Good luck

Mixing Bone Grafts

Answered By: Dr. Leonard Smith - San Jose , CA

Dear Julie: yes mixing of different bone graft materials is common practice. The dental profession has many established techniques and many new protocols to improve the outcome of bone grafts. Treatment is always very specific to the individual patient. Addition of healing factors via your own blood or using recombinant (genetically engineered) products is now very common. Ask you dentist as to his/her experience with grafting and implant treatment and what results are expected and why. An experienced implant dentist will be glad to share experience with the patient.
