Managing bone tissue regeneration is a key problem in traumatology and orthopedics. The researches proved that thyroid hormones affect hemostasis and reparative regeneration of bone tissue favorably and promote osteogenesis and bone consolidation.The aim of this research is to study the influence of disturbed reparative regeneration on the concentration of thyroid hormones in blood in the dynamics. Experimental research on rabbits (n=12) with modelling of disturbed reparative regeneration revealed disorder in thyroid hormones synthesis and different directions of T3 and unbound T3 production on the 35th day when the maxi-mum decrease of T3 (2times) and unbound T3 (1.5times) compared to normal values was registered. The analysis of production of T4 and unbound T4 revealed suppression of the values from the 1st to 50th day and gradual increase in unbound T4 from the 50th day. The most significant manifestation of thyroid gland reaction on the disturbed reparative regeneration of shin bones was the decrease in T3 and peripheral conversion of thyroid hormones up to 50th day with formation of false joint in these terms.

Background.Due to the prevalence of Vitamin D deficiency as well as the frequency of reconstructive surgical interventions followed by dental implantation, the issue arises concerning the effect of Vitamin D on reparative regeneration of bone and osseointegration of dental implants.The purpose using literature data we are conducting an impact assessment of vitamin D on reparative regeneration of bone tissue, in particular, after oral reconstruction surgeries and dental implantation.Methods.Retrieval, systematization and analysis of scientific data on application of vitamin D supplementation and its effect on reparative regeneration of jaw bone tissue.The conclusions.For the most part, the positive effect exerted on reparative regeneration of jaw bone tissue and osseointegration of dental implants is due to the role of vitamin D in physiological processes evolving in bone tissue, namely maintenance of calcium and phosphate exchange through intestinal absorption and TNF, RANKL (Receptor activator of nuclear factor kappa-B ligand) and consequently differentiation of precursors to osteoclasts into osteoclasts through VDR stimulation (VitaminD Receptor) receptors for further osteogenesis. Also, according to literature data, FGF23 (Fibroblast Growth Factor) protein is a marker of osteoblasts differentiation into osteocytes, it is also known that FGF23 and 1,25(ОН)2D3 are genetically related. FGF23 is the main regulator of both phosphate exchange in bones and metabolism of vitamin D and its metabolites. Besides, indirect anti-inflammatory effect has been observed thanks to inhibition of pro-inflammatory cytokine secretion. Taking into account the abovementioned data, of particular relevance is the definition of serum concentration 25(ОН)D and development of schemes of vitamin D level pre-surgery correction in patients, who have to undergo oral reconstruction surgeries and dental implantation. Mass spectrometry is a promising diagnostic method for determining the level of vitamin D in a body, as it allows to identify the actual amount of vitamin D free from admixture of other steroid hormones. The introduction of this method into clinical practice will allow to monitor the level of vitamin D in patients, receiving reconstructive and rehabilitative treatment.

Introduction: In recent years, procedures with the use of dental implants have increased worldwide, reaching approximately one million dental implants per year. In recent years, a platelet concentrate called FRP (fibrin-rich plasma) has been the subject of clinical studies. Associated with this, the biomaterial Bio-Oss® (Geistlich), as it is biodegradable, biocompatible, non-toxic, and has low immunogenicity, and bio stimulators can act in the regeneration of bone tissue, as it establishes with the cells the appropriate biological niche (favorable microenvironment) for bone growth. Objective: Therefore, the present study aimed to evaluate, through a brief systematic review, the results that involve bone formation for dental implantation, with the use of biomaterials such as fibrin-rich plasma and Bio-Oss®. Methods: The model used for the review was PRISMA. Was used databases such as Scopus, Scielo, Lilacs, Google Scholar, PubMed. Results: Fibrin-rich plasma (FRP) as an autologous biomaterial for use in oral and maxillofacial surgery presents most leukocytes, platelets, and growth factors, forming a fibrin matrix, with three-dimensional architecture. The Bio-Oss® biomaterial (Geistlich), as it is biodegradable, biocompatible, non-toxic, and has low immunogenicity and bio stimulators can act in the regeneration of bone tissue, since it establishes with the adenomatous mesenchymal stem cells the appropriate biological niche for bone growth and, thus, allowing the dental implant to be as effective as possible. Conclusion: The use of FRP associated with Bio-Oss® seems to illustrate high success rates with minimal costs, which may reduce the amount of bone graft needed to fill the sinus cavity, reducing the costs of the procedure.

Results of the study of the drug from calcium salts of amino acids (calcium diglycinate, calcium di-L-prolinate) on the model of osteoporosis in animals are described. The test substance was found to have better therapeutic effect in the regeneration of bone tissue in comparison with the drug containing calcium carbonate. The drug containing calcium salts of glycine and L-proline can be used for prevention and treatment of osteoporosis.
