Oragraft Cancellous Cube

OraGraft Cancellous Cube

A block of solid cancellous bone allowing for space maintenance and rapid remodeling due to its trabecular architecture.
Preservation Method:  Freeze Dried 

“…a solid block graft is less prone to micromotion than particulate graft, thus providing more predictability…. the use of particulate with the addition of metal mesh or a nonresorbable titanium reinforced membrane make the procedure unnecessarily complex.1

“The compromised alveolar ridge in the anterior maxilla does not provide a natural cavity to contain the particulated grafting material as seen in the sinuses. Therefore the graft must possess strength and rigidity to allow its fixation in the recipient site, and the three dimensional stability to withstand muscular forces.”2

In a systematic review, it was concluded that the use of allogenic bone block grafts represent a reliable alternative to autogenous block grafts for augmenting the atrophic maxilla.3

Oragraft Cortical Plate

OraGraft Cortical Plate

The cortical plate is an osteoconductive graft made from 100% donated  human cortical bone which has been shown to remodel slowly in  a controlled fashion and can be used as a substitute for autologous bone recovered from the mandibular shelf, eliminating the need for a second surgical site. 
Preservation Method: Preservon

Studies have shown that horizontal and vertical augmentation of an atrophied ridge is possible with thin blocks in combination with particulate bone grafts.

A case was described using allograft bone for the Khoury technique in order to avoid some of the potential problems with autogenous recovery.2

Oragraft Ilium Strip (Bicortical)

OraGraft Ilium Strip (Bicortical)

Comprised of two strong outer cortical walls with cancellous bone located within, and can be affixed using standard bone screws and easily trimmed using standard instrumentation.
Preservation Method: Freeze Dried or Preservon

Oragraft Unicortical Block

OraGraft Unicortical Block

An allograft implant composed of a single cortical wall with attached cancellous. It's supported by clinical data and is an effective alternative to autograft for alveolar ridge reconstruction.
Preservation Method: Preservon 

 “A solid block graft is less prone to micromotion than particulate graft, thus providing more predictability. In some cases, depending on the ridge area needing augmentation, the use of particulate with the addition of metal mesh or a nonresorbable titanium reinforced membrane makes the procedure unnecessarily complex.”1

“The compromised alveolar ridge in the anterior maxilla does not provide a natural cavity to contain the particulated grafting material as seen in the sinuses. Therefore the graft must possess strength and rigidity to allow its fixation in the recipient site, and the three dimensional stability to withstand muscular forces.”2

“Although autogenous bone block grafting yields satisfactory results, this technique is associated with disadvantages such as prolonged operation times, limited graft acquisition, and risk for damage to adjacent teeth, neurosensory deficits, donor area flap exposure, bleeding and infection.”3

Oragraft MD 70/30

OraGraft MD 70/30

The combination of 70% mineralized and 30% demineralized allograft bone leverages the benefits of space maintenance with ground cortical with the osteoinductive potential of demineralized ground cortical.
Preservation Method: Freeze Dried
Particle Size: 250-1000 microns

The combination of mineralized and demineralized bone has been shown to maintain space and have some osteoinductive potential1  

In a review article of block grafting, the authors recommend that the filler for block grafting be a slow resorbing FDBA with the addition of growth factors to accelerate the healing process.2

Oragraft Mineralized Cancellous  Particulate

OraGraft Mineralized Cancellous Particulate

Osteoconductive graft with an open trabecular structure that supports angiogenesis.
Preservation Method: Freeze Dried
Particle Size: 250-1000 microns   

A clinical demonstrated that tenting of the periosteum and soft tissue matrix with titanium screws maintains space and minimizes resorption of mineralized particulate allograft. This technique offers predictable, functional and esthetic reconstruction of large vertical defects without the use of autogenous bone and is capable of osseointegration.1

Another clinical study describes a technique for maxillary bone grafting that may be used to reconstruct a portion of the maxilla lost due to trauma or tumor surgery, or to augment as osseous deficient edentulous maxillary alveolar ridge.2
