Comparison between porous hydroxyapatite of chorale and autogenous bony graft in rabbits

The transplantation of autogenous bone continues being used with success, in spite of the disadvantages that it presents, mainly in what refers the increased morbidity, additional operations and increase of the cost. The objective of this research was to verify the integration of the porous hydroxyapatite of chorale as biological alternative in ceramic form to substitute the autogenous bony graft. Forty-two New Zealand rabbits were submitted to na standard condylar defect witch were randomic implanted by autogenous bony graft as porous hydroxyapatite of chorale. We made clinical, macroscopic, radiographic and histologic study among the time of evolution of two, four and twelve weeks, respectively. The results were similar between the autogenous graft and the porous hydroxyapatite of chorale in the evolution of twelve weeks. It was ended that the porous hydroxyapatite of chorale is a substitute adapted to the autogenous bony graft in rabbits.
