AB  - The lack of bone in the jaw tegmenta inflicts major problem and leads to an inability to adequately treat stomatoprosthetic patients. If the bone tissue damage is minor, the balanced activities of osteoblasts and bone osteoclasts can repair it independently. If the damage is bigger it is necessary to support the biological potential to repair the bone, and for that reason nanoparticle
biomaterial Ca / Co-HAp was used in this study. The research was done on rats with uniform anatomical and physiological characteristics. Assessment of repair and consolidation of the jaw bone tegmenta was performed by istomorphometric and SEM analysis. The best results were obtained in the experimental group of animals where the Ca / Co-Hap was mixed with autologous
plasma. Following the implementation of the above mentioned nanocomposites, a significant formation of new bone was evident on the SEM analysis, as well as the rising of histomorphometric parameters of bone formation, which indicates that the Ca / Co-HAp nanocomposite is the material of choice for the rapid regeneration and repair of bone jaw tegmenta.

AB  - In recent years, calcium hydroxyapatite (HAp) and its substituents are increasingly used in dentistry and medicine. The influence of nanoparticles Ca / Co-HAp in strengthening weak osteoporotic bone jaw tegmenta was tested in an experimental model. The study was conducted on Wistar soy rats, aged 6-8 weeks. The biomaterial was implanted in the osteoporoticly weakened mandible of these animals. The best results in the strengthening of the lower jaw bone tegmenta were achieved 24 weeks after implantation of hydroxyapatite nanoparticles in which the calcium ion was substituted with 12% of cobalt ions. Histochemical parameters of bone synthesis were in a statistically significant increase. SEM analysis showed a high degree of osteogenetic ability of nano-particulate material implanted in the bone defect.

AB  - Huge range of tested biomaterials in recent decades has emerged as an ideal scaffold for cell growth, but few have demonstrated clinical efficacy. Among them, synthetic hydroxyapatite (HAp, Ca10(PO4)6(OH)2) is the most promising because of its biocompatibility, bioactivity, and osteoconductivity. Biocompatibility represents the primary concern for any material to be used as a substitute for natural tissue. Hydroxyapatite particles interact with numerous cellular systems in vivo, and some of these interactions may lead to cell damage and to stimulate platelet activation, coagulation and thrombus formation. The aim of this work was to examine the hemocompatibility of nanocalcium hydroxyapatite substituted with 5% and 12% cobalt (Ca /CoHAp) and hydroxyapatite/polylactidcoglicolid (HAp / PLGA) in relation to pure HAp by testing their hemolytic activities. The results show the discrepancy in hemolytic activity of implanted matherials. The degree of crystallinity of samples had a more dominant influence on hemolysis than the percentage of substituted cobalt. Hemolysis ratios of the nanocalcium hydroxyapatite substituted with cobalt samples were below 3%, indicating good blood compatibility and that they are promising for medical application.
