Autogenous dentin matrix vs. Bio-Oss

Several companies are now marketing machines that allow clinicians to prepare chairside bone graft material specific to the patient by using the patient’s own extracted teeth. The resulting graft is called autogenous tooth graft material (AutoBT) or sometimes autogenous dentin. The question, of course, is how these dentin grafts compare to more traditional graft materials. A recent study1 aimed to do just that, by comparing autogenous tooth graft material to Bio-Oss ® ( the popular anorganic bovine bone graft material).

The conclusion:

Autogenous demineralized dentin matrix from extracted tooth grafted to extraction sockets for the augmentation of vertical dimension was as effective as augmentation using anorganic bovine bone. Both groups showed favorable wound healing, similar amount of implant stability, and histologically confirmed new bone formation. Thus, the results of this study suggest that autogenous tooth graft material is a viable option for alveolar bone augmentation following dental extraction. Read More 1

Does anyone have alot of clinical experience yet with autogenous tooth graft material? How does it compare to other graft materials you have used?

  1. Been using it for a couple of years now. Works awesome and takes some of the issues with donor material out of the equation. I use it in combination with Silfradent’s medifuge CGF. It does add 15-20 minutes more time to the procedure unless you can really train staff well to get it all done for you.

  2. I have been doing dentin grafting since the ADA meeting in San Antonio three years ago when I meet Amit Binderman and his son. “It’s like your own bone and twice the bmp as regular bone” is a great selling point. It’s relatively less investment in bone graft materials. I have mixed it with BioOss granules (hamburger helper) with great results.
    I have utilized wisdom teeth, 4 at a time in one container. I have built ridges and periodontal bone grafting and implant sites simultaneously with marked success. The grinding machine does its work while I am doing someklthing else; so no waste of time.
    I do not have to charge as much since there is less monetary outlay on my part. And patients appreciate that. I have not had any post op complications to date. I always clean up grafting sites with scaling, chlorseptic subgingival irrigation and scrub the outer tissues with the Chlorseptic to get rid of any possible contamination before beginning surgery. I don’t prescribe anything for pain more than three Aleve q 8 h- beginning one hour before surgery for patient comfort and less swelling.
