The iliac crest is a common site for bone procurement in oral and maxillofacial surgery. The goal of this study was to evaluate the potential for bone regeneration in the presence of four common hemostatic agents in a manner that parallels iliac bone procurement in humans. The agents evaluated were 1) Avitene (microfibrillar collagen; Medchem Products, Inc, Woburn, MA); 2) bone wax (beeswax with isopropyl palmitate; Ethicon, Inc, Somerville, NJ); 3) Gelfoam (absorbable gelatin sponge; The Upjohn Company, Kalamazoo, MI); and 4) Surgicel (oxidized regenerated cellulose; Johnson & Johnson Products, Inc, Patient Care Division, New Brunswick, NJ). Five surgical defects in each of four dogs were created for placement of the four materials; one defect served as an empty control site. The dogs were then allowed to heal over a 2-month period. Radiographic and histologic examination showed new bone formation in the presence of Avitene, Surgicel, and Gelfoam. Residual material incorporated in bone, without foreign-body response, was noted in the Avitene and Gelfoam sites. Bone wax, however, showed an intense foreign-body reaction, characterized by giant cells, plasma cells, fibrous granulation tissue, and lack of bone reformation. On the basis of these initial findings, it was concluded that Surgicel, Avitene, and Gelfoam may be adequate hemostatic agents for use in iliac bone procurement, whereas the use of bone wax appears to be contraindicated.
