Management of Hard Tissue Avulsive Wounds and Management of Orofacial Fractures.
Abstract
Studies were conducted to develop biodegradable ceramics and collagen-impregnated porous ceramics for evaluation as potential materials for management of hard tissue avulsive wounds. Also, studies were conducted to prepare and characterize the attachment of collagen-coated dense alumina specimens for implant studies. In vivo studies at the U.S. Army Institute of Dental Research (USAIDR) have shown that a sintered porous calcium phosphate (Ca(PO3)2) ceramic was bio-compatible, was invaded rapidly by bone and tissue, and had shown some definite evidence of bioresorption. These findings indicate that the porous calcium phosphate has potential as a biodegradable material which permits bone ingrowth to facilitate repair of avulsive wounds and that it eventually is resorbed, being totally replaced by bone, thereby restoring the avulsed area to its natural state. In vivo studies with porous samples of tricalcium phosphate, Ca3(PO4)2, are also being conducted at USAIDR. Porous phosphate-bonded alumina impregnated with bonded proteins (collagen or albumin) were also developed and characterized for in vivo studies. (Author)
