When an individual loses tooth, an extraction socket is formed in the mouth. Typically sufficient bone is not available in the socket to place an implant. Bone grafts like NanoGen, offered by Orthogen, LLC, needs to be placed in the socket to encourage bone regeneration. A clinical study published in the journal Clinical Advances in Periodontics has revealed the effective use of NanoGen for guided bone regeneration in a molar extraction socket. Clinical Advances in Periodontics is an official journal of the American Academy of Periodontics.
