Preparation for regeneration of postoperative and post-traumatic bone defects

摘要

According to the invention preparation for regeneration of bone defects is employed in many branches of medicine, especially in orthopedics, dental surgery, reconstructive surgery, periodonthology and implantology. The preparation has been developed on the basis of inorganic chemical compound naturally occurring, i.e. deproteinized human bone, and on the basis of at least one of inorganic chemical compounds synthetically occurring, i.e. bioglass in the form of granulated highcalcium product (54% mol. CaO), obtained with the use of zol-gel method in the system CaO-SiO 2 -P 2 O 5 , of density 2,9082 g/cm 3 , with phase composition with a dominant glassy phase and beginnings of crystallization of apatite, heat treated at temperature of 800°C, having a specific surface BET 57,8166 m 2 /g and/or tricalcium phosphate - TCP in the form of granulated product with chemical formula Ca3 (PO 4 ) 2 . As a component deproteinized particlesof human bone are used, favourably with granulation 0,3-0,5 mm, bioglass favourably with granulation 0,3-0,5 mm and/or TCP - tricalcium phosphate favourably with granulation 0,3-0,5 mm.
The amount of bone material in the preparation amounts favourably to 70-80% of the preparation weight, the amount of bioglass in preparation amounts favourably to 10-15% of the preparation weight, the amount of TCP in the preparation amounts favourably to 10-15% of the preparation weight.
During implantation binder in the form of blood from patient's operative wound is introduced into the preparation. Amount of the preparation in mixture favourably amounts to 75-80% of the mixture weight and the amount of own blood favourably amounts to 20-25% of the mixture weight.
