Composite biomaterials, like calciumphosphate/bioresorbable polymer, offer excellent potential for reconstruction and reparation of bone tissue defects induced by different sources. In this paper synthesis of calciumphosphate/poly-DL-lactide-co-glycolide (BCP/DLPLG) composite biomaterial formed as filler and blocks was studied. BCP/DLPLG composite biomaterial was produced in the form of spherical granules of BCP covered by a DLPLG layer, average diameter of 150-250 µm. By cold and hot pressing of granules at up to 10000 kg/cm2, blocks with fine distribution of phases and porosity up to 3% were obtained. Characterization was performed by wide-angle X-ray structural analysis (WAXS), differential scanning calorimetry (DSC), scanning electron microscopy (SEM), infrared spectroscopy (IR), and mechanical properties by defining the compressive strength. In vitro citotoxicity research was carried out on cellular cultures of fibroblasts of human (MRC5) and mouse (L929). In vivo research was performed in two steps. Reparatory ability of BCP/DLPLG in mice was examined in the first step, and then bone tissue reconstruction possibilities on 10 patients in the next step. In vitro tests showed very good fibroblast adhesion and non-citotoxicity of the composite. A material is considered non-cytotoxic if the cell survival is above 50 %, and in our case it was 90%. In vivo research on mice indicated high level of reparatory ability of this composite with formation of new bone and vascular tissue six weeks after reparation. Application of this composite for healing infrabone defects of patients showed a high level of osseous regeneration.

Numerous dental manipulations are accompanied by bone injuries. Various types of drug correction are widely used for correction and optimization of bone tissue reconstruction after bone-traumatic injury. The evaluation of the course of reparative osteogenesis becomes possible with the x-ray methods which gives the possibility to evaluate and predict early quantitative and qualitative changes in various pathological conditions, as well as to trace their dynamics in clinical and experimental conditions. In our research we have find out the peculiarities of the density dynamics of the bone tissue of the mandible after causing bone-traumatic injury to intact animals and animals that have been taking nalbuphine for a long time, as well as after treatment with lincomycin.

The research on the influence of ethanol and water extracts from propolis on the regeneration of tissues important for the organism, such as skin tissue, bone tissue, cartilaginous tissue, and tooth tissue have been conducted for over 50 years. The research literature of Polish scientists played a significant role in this respect. The research on the influence of propolis on the regeneration of skin, bone, cartilaginous and tooth tissue has been reviewed. Studies carried out on experimental animals indicate that both ethanol extracts (EEP) and aqueous extracts (WEP) from propolis are characterized by a distinct regenerating effect on the above mentioned types of tissues. There was noticed a significant acceleration of healing experimental wounds under the influence of EEP and WEP, accelerated bone tissue reconstruction as well as rapid reproduction of cartilaginous and dental tissues. In the context of the above data, it can be assumed that both EEP and WEP are characterized by a distinct, significant influence regenerating the skin, bone, cartilaginous and tooth tissues. These extracts can be successfully used in the treatment of disorders of these tissues in humans.
