AB  - The loss of teeth and damage to the jaw bone occur under different circumstances. The deficit may be the result of wearing inadequate dentures, residual ridge resorption, osteoporosis, periodontal disease, trauma, tumors, radiation, etc. The deficit of bone tissue can be a substantial problem because it prevents adequate prosthetic patient care and restoration of disturbed functions of stomatognathic system. With such patients, there is often a need for preprosthetic surgical procedure through the application of various techniques and materials in order to resolve aftermentioned bone shortcomings. The most appropriate biological materials for the reconstruction are autogenous bone graft and artificial bone. With the development of technology and specific
biomaterials it is tried to avoid situations that require autogenous bone grafting, since it involvs long surgical procedure with the possibility of postoperative complications. The application of synthetic biomaterials, whose properties are similar to natural hydroxyapatite, promotes the biological potential for bone tissue repair. Synthetic biomaterials have great biocompatibility and sterility and do not act antigenicaly. The disadvantages of this material are overcome by the addition of organic polymers. Thanks to the stability and flexibility of hydroxyapatite structure, a large number of ionic changes are possible, both cationic and anionic, which improve the characteristics of synthetic hydroxyapatite. Biomaterials that include different drugs, such as antibiotics, vitamins and other preparations, could be used for the treatment of complications after surgical procedures and infection of bone tissue. Our experimental studies indicate that biomaterials based on hydroxyapatite are valuable materials that can be used for preprosthetic surgical preparation.

AB  - One of the trends in the treatment of reduced bone density is in oral implantology through the use of new biomaterials with paramagnetic properties. In this in vivo study the effect of Ca /Co-HAp nanoparticles (calcium/cobalt-hydroxiapatite) in the regeneration of the reduced alveolar bone density in experimental animals was examined by analyzing both the biochemical and histochemical markers and through analysis of alveolar bone density. The research was carried out on female Westar rats, aged 6-8 weeks, whom have been implanted nanobiomaterial in reduced alveolar bone density. Good results in regeneration of reduced bone density were achieved in six weeks after implantation of the nanoparticles with paramagnetic properties. Biochemical markers of osteogenesis showed statistically significant rise. Histological analysis revealed high level reparatory skills of the biocomposite implanted in the bone defect, while X-ray analyses evidenced rise of bone density. Implantation of Ca/Co-Hap enables rapid new formation, thus becoming the material of choice for accelerated reduced bone density regeneration.

AB  - This study examined the role of Ca / Co-HAp nanoparticles on time distance in regeneration of osteoporotic alveolar bone in rats by biochemical blood markers analysis (ALP, Ca, Mg, P) and through histochemical analysis. The research was carried out on female Westar rats, aged 6-8 weeks. The obtained results for the biochemical blood markers showed statistically significant rise. Histological analysis revealed high level reparatory skills of the biocomposite implanted in the bone defect as early as in the mineralized tissues. It can be concluded that Ca/Co-HAp stimulates the regeneration of osteoporotic alveolar bone in tested animals as confirmed by the increased levels of biochemical blood markers and through histochemical analysis. Therefore, it can be concluded that Ca/Co-HAp nanocomposite should be choise material in the osteoconstructive processes in the future.

AB  - Antimicrobial materials based on hydroxyapatite are potentially attractive in a wide variety of medical and stomatological applications. The objective of this paper is to examine antimicrobic activity of cobalt-substituted calcium hydroxyapatite nanopowders and biphased calciumphosphate/ poli-lactide-co-glicolide. The antimicrobial effects of these substances (powders) against two pathogen bacterial strains- Escherichia coli (ATCC 25922) and Staphylococcus aureus (ATCC 25923) were tested by disc diffusion method and quantitative antimicrobial test in liquid medium. It was noted that the inhibition zone of the bacterial cells S. aureus around the sample of the Ca/Co- HAp, was a lot bigger compared to the inhibition zone of bacterial cells E. coli around the sample of the mentioned biomaterial, which means that this material has bigger antimicrobic activity on S. aureus, in relation to E. coli. Quantitative antimicrobial test in liquid medium demonstrate that cobalt-substituted calcium hydroxyapatite samples show viable cells reduction of both tested microorganisms. It may be concluded that nanoparticles of cobalt-substituted calcium hydoxyapatite nano-powders has a satisfactory antimicrobic activity according to the tested bacteria strain.
