RESUMEN
A 1 cm piece of m and ible was resected in 6 rabbits and replaced by an equal graft of a newly developed material [veterinary porous hydroxyapatite [VHAP]]. X-ray studies were done preoperatively, immediate postoperatively as well as at 1, 2 and 3 months later. It was evident radiologically that the material was completely united to the host bone after 3 months. The rabbits were sacrificed at 6 weeks and 3 months [3 rabbits each] and the m and ible was examined by scanning electron-microscopy which showed complete integration of the graft in the host bone. Also, the chemical structure of the graft was studied by infrared spectrographs. Clinically, the graft was completely incorporated in the m and ible without any complications. One can suggest using material in human to reconstruct post-surgical m and ibular defects
