Compared with smaller particles, larger particles possess greater mechanical resistance, reducing the risk of premature chemical dissolution and improving space-maintaining capability.
Allograft bone substitutes must be retained during bone formation in order to support osteoblast function. In instances where bone substitutes are not successfully retained, there is an elevated risk of defective, insufficient bone formation. Conversely, smaller particles possess greater shapeability and more rapid dissolution, reducing the overall time needed for bone formation.
Vitality Bone Particulate Allograft consists of a 500-1000 micron particle size in order to maximize the quality of bone formation while maintaining a turnover period of approximately 4 months.
