The Osteoinductive Potential of Partially Demineralized Bone Matrix and the Possibility of Its Use in Clinical Practice

Abstract

Today autografts are considered to be an optimal material for bone grafting. However, the collection of material and its clinical use is associated with several serious drawbacks, and therefore, in reconstructive surgery, a search for alternative treatment approaches is being conducted. A bone transplant from another person (allo-osteoplasty) is the most natural and logical option for replacing an autobone. Since 1965, allogeneic implants of a partially demineralized bone matrix combining osteoinductive and osteoconductive action have been used in clinical practice. However, the clinical results of the use of this material turned out to be ambiguous, which is due, first of all, to the significant variability of the osteoplastic potential of its various samples. For this reason, in clinical practice, sometimes preference is given to samples of non-demineralized allobone, which retain its structure longer. In this paper, we consider factors affecting the osteoinductive activity of a partially demineralized bone matrix, related both to the technological issues of its preparation and to the clinical conditions of use. Issues of the possible improvement of this material were discussed with a view to its further use in medical practice.
