Management of Hard Tissue Avulsive Wounds and Management of Orofacial Fractures.
Abstract
Research studies were conducted to produce and evaluate a high-quality directional porosity resorbable calcium phosphate ceramic material for use in the management of hard tissue avulsive wounds and orofacial fractures. The previous year's efforts demonstrated that directional porosity would allow adequate ingrowth of bone through the biomaterial prior to loss of mechanical integrity of the biomaterial. The overall objective is to produce a completely resorbable biomaterial which will promote bone formation and after the bone remodeling degradation process be completely replaced by bone. The advanced materials produced for this present investigation calendered or rolled to form a serrated surface and then stacked and sintered together to form a unique undirectional porosity as required by the particular implant situation. The technique allows directional porosity material to be formed in blocks of high-strength material with continuous pores of large diameter. The pores can be specifically oriented, and the surrounding material can be made dense enough to provide a high-strength scaffold.
