Puros® Demineralized Bone Matrix (DBM)

Product Description

This demineralized bone matrix is comprised of 100% demineralized human bone. Puros DBM is a ready-to-use putty formulation that delivers excellent handling and timesaving convenience. It is also easily malleable for packing and molding into various shapes and sizes. Puros DBM is available in two versatile forms: putty and putty with cortico-cancellous allograft chips.

Puros DBM is a natural choice for active, robust, and moldable allograft. The surgeon can perform procedures with confidence knowing that every lot is tested for osteoinductive potential using an in vivo rat assay.1* Testing indicates that Puros DBM retains its osteoinductive potential throughout its shelf life.2
