title: Particle size of periodontal bone grafting materials.
abstract: Samples of autogenous bone obtained by high speed burs, low speed burs, hand chisels and bone blending; freeze-dried bone purchased from a tissue bank and alloplastic materials, such as Calcitite, Durapatite, Periograf and Synthograft used as donor material for periodontal bone grafting procedures, were evaluated histometrically. Particle sizes ranged from a mean of 210 X 105 mu for bone blend to 1559 X 783 mu for hand-chisel samples. Except for those two materials, all of the others were in the 300 to 500 microns (0.3-0.5 mm) range that seems to be preferred for use in periodontal defects.
