CLINICAL PRACTICE

The Safety of Bone Allografts Used in Dentistry

A Review



Dan Holtzclaw, DDS, MS, Nicholas Toscano, DDS, MS, Lisa Eisenlohr, PhD and Don Callan, DDS

Background. Recent media reports concerning "stolen body parts" have shaken the public’s trust in the safety of and the use of ethical practices involving human allografts. The authors provide a comprehensive review of the safety aspects of human bone allografts.

Methods. The authors reviewed U.S. government regulations, industry standards, independent industry association guidelines, company guidelines and scientific articles related to the use of human bone allografts in the practice of dentistry published in the English language.

Results. The use of human bone allografts in the practice of dentistry involves the steps of procurement, processing, use and tracking. Rigorous donor screening and aseptic proprietary processing programs have rendered the use of human bone allografts safe and effective as a treatment option.

Conclusions. When purchasing human bone allografts for the practice of dentistry, one should choose products accredited by the American Association of Tissue Banks for meeting uniformly high safety and quality control measures.

Clinical Implications. Knowledge of human bone allograft procurement, processing, use and tracking procedures may allow dental clinicians to better educate their patients and address concerns about this valuable treatment option.
