METHOD FOR PREDICTING THE HIGH EFFICIENCY OF TITANIUM IMPLANTS USING THE X-RAY MICROTOMOGRAPHY METHOD

摘要

FIELD: medicine.;SUBSTANCE: invention relates to medicine and can be used in traumatology, orthopedics and dentistry to predict the high efficiency of biocompatible titanium alloys and titanium implants with coatings. Method is carried out using the X-ray microtomography method, where bone tissue is examined around the implant and determined by X-ray microtomography for 10–50 days after implantation, the Hounsfield X-ray density (HU) mineral density index (BMD), the ratio of the volume of trabeculae to total bone volume (TrV/Total V), and the ratio of tissue porosity to total volume of bone tissue (PV/Total V). With X-ray density indicator according to Hounsfield 2,400–2,500 conventional units, BMD – 0.83–0.92 g/cm³, TrV/Total V – 72.2–87.6 %, PV/Total V – 12.4–27.8 % predict high efficiency of titanium implants.;EFFECT: proposed method allows to predict the effectiveness of the use of various titanium implants by X-ray microtomography.;1 cl, 3 ex, 4 dwg, 1 tbl
