Influence of demineralized bone matrix's embryonic origin on bone formation: an experimental study in rats.

Background: There are results suggesting that differences regarding bone-inducing potential, in terms of amount and/or rate of bone formation, exist between demineralized bone matrices (DBMs) of different embryonic origins.

Purpose: The aim of the present study was to examine whether the embryonic origin of DBM affects bone formation when used as an adjunct to guided tissue regeneration (GTR).

Materials And Methods: Endomembranous (EM) and endochondral (ECH) DBMs were produced from calvarial and long bones of rats, respectively.
