What is the consistency of the graft material?
The graft material is in the form of thin convoluted shavings, and with their randomized form, there is a relative increase in the graft volume in comparison to the original bone volume that was harvested. The interstices created by the shavings form a porous matrix that is filled with blood from the bone’s surface as the shavings are being harvested. The exposed collagen promotes coagulation of the blood and binds the graft together with a firm mortar like consistency. This allows the graft material to be easily handled and packed securely into place. These shavings, in comparison to particulate grafts from ronguers or bone mills, do not have any sharp edges. This allows the material to be placed securely in position as compared to chip-like particles. And without sharp edges, the graft is more gentle on the flap and from our clinical experience, allows the flap to adhere to the graft and minimize the tension across the wound closure.
