Use of hydroxyapatite in the treatment of bone cavities after the removal of inflammatory lesions within the jaws
Hydroxyapatite in the form of granules of different sizes is a popular material used in oral surgery. It is widely used in the guided bone regeneration technique (GBR). The essence of this method is to assist the healing process of bone defects by means of implantation material, natural or synthetic, which is placed within the bone cavity. Hydroxyapatite implant reduces the volume of the hematoma forming in the wound, prevents infection and has osteoconductive properties. It also increases local bone mechanical strength in the treated area. Three cases of patients with bone cavities after surgical treatment of inflammatory lesions have been described. The cavities have been filled with hydroxyapatite granules. The material has been used in two cases in animals in the treatment of oro-nasal fistula and in one case in a human after enucleation of an inflammatory lesion. It has been proved that hydroxyapatite as an implantation material provides better and faster recovery of bone lesions, while the bone that forms on the implant has a more regular structure than bone generated only on the basis of a clot. In the described cases the treatment of bone cavities in animals and humans proved to be a hydroxyapatite biomaterial accelerating the reconstruction of bone tissue..
