Bone Grafting (Oral-Maxillofacial and Dental)
Grafton™ demineralized bone matrix (DBM) is the most utilized and scientifically studied DBM brand.* Our aseptic processing technology preserves the function of naturally occurring growth factors — yielding Grafton DBM’s consistently high osteoinductivity scores.† Proprietary fiber technology offers enhanced osteoconductive scaffold.1
The form of Grafton used in dental procedures is Grafton Plugs. These cube-shaped grafts can be placed in bone voids ranging from facet joints to extraction sockets. Size: 8mm × 8mm × 10mm.
Grafton DBM is intended to be packed into bony voids or gaps to fill and/or augment dental intraosseous, oral and cranio-/maxillofacial defects. These defects may be surgically created osseous defects or osseous defects created from traumatic injury to the bone, including periodontal/infra bony defects; alveolar ridge augmentation (sinusotomy, osteotomy, cystectomy); dental extraction sites (ridge maintenance, implant preparation/placement); sinus lifts; cystic defects; craniofacial augmentation.
Grafton DBM may be used alone in a manner comparable to autogenous bone chips or allograft bone particulate (demineralized freeze-dried bone), or it may be mixed with either allograft or autograft bone or bone marrow as a bone graft extender. Grafton DBM is indicated only for bony voids or gaps that are not intrinsic to the stability of the bony structure. Grafton DBM is resorbed/remodeled and is replaced by host bone during the healing process.
Medtronic’s processing facility, located in Eatontown, New Jersey, is accredited by the American Association of Tissue Banks (AATB), and is committed to providing quality and innovation in its various demineralized bone matrix tissue forms.
The proprietary demineralization process inactivates viruses while preserving the osteoinductive activity necessary for new bone formation. The D-Min™ process ensures the viral inactivation and osteoinductivity of demineralized bone matrix.2,3
Medtronic was the first to market with a fiber-based DBM. Our aseptically processed fibers have some of the highest osteoinductive scores† on the market and this interconnected mesh of fibers enhances the osteoconductive potential of the product by providing a path for cellular infiltration.
Because allograft tissue processing, including demineralization, has evolved over time and is performed by numerous processors, it is important to recognize that not all demineralization processes are alike. Process variables include:
We use our proprietary D-Min process to demineralize the allograft tissue that goes into the different Grafton Bone Graft forms. Controls in the D-Min process eliminate many of the variables that can affect the osteoinductivity of demineralized bone matrix. Through a prospective randomized study of production allograft, we were able to validate that the D-Min process yields a consistently osteoinductive product. Product processing consistency is confirmed via ongoing testing.
Medtronic follows AATB guidelines in sourcing donors and works to maximize the use of donated tissue.
Medtronic conducted an extensive study assessing the impact of age and gender on osteoinductivity. Osteoinductivity scores for each age group and gender were determined using an in vivo athymic rat assay. Donors were grouped in the age ranges specified. Insufficient numbers of 76-85-year-old females resulted in exclusion from analysis. The orange bars represent results from female donors and the blue bars represent male donors.7

The following are contraindications for the use of Grafton DBM and Grafton Plus™ DBM:
This allograft may contain trace amounts of antibiotics (gentamicin), surfactant, and other processing solutions. Caution should be exercised if the patient is allergic to these antibiotics or chemicals. Grafton Plus DBM Paste contains starch. Therefore, caution should be exercised in using Grafton Plus DBM Paste in a patient with a starch allergy and/or amylase deficiency.
