PURPOSE:
Bone substitute.
DESCRIPTION:
The effectiveness of the use of bioactive glass-crystalline coatings on titanium alloys based on calcium silicophosphate glass-crystalline glasses in orthopedics and dentistry as substitutes for bone tissue is explained by the unique combination of physicochemical, mechanical, technological and clinical-biological properties of a composite based on a surface-active glass material and a titanium alloy with high compatibility with bone tissue. Developed domestic bioactive glass-crystalline coatings for titanium alloys with an adjustable level of solubility and mechanical properties similar to natural bone based on calcium silicophosphate glasses and technologies for their production.
TECHNICAL CHARACTERISTICS:
The firing of the coating is carried out under the conditions of a one-stage low-temperature heat treatment at T <= 850 ° C, preventing the formation of scale and a brittle alpha layer of considerable thickness (T> = 850 ° C). Mechanical properties of synthesized coatings (HV = 5440-5660 MPa, K1s = 2.01 – 2.73 MPa m-1/2) and their surface properties (Ra = 3.4 – 10.0 μm, PEP = 51 – 60 mJ / m2) provides the necessary physicochemical properties of composites and allow them to be used under cyclic dynamic loads.
ADVANTAGES:
The period of fusion with the bone was reduced to 1 month.
TECHNICAL AND ECONOMIC EFFECT:
The combination of properties allows increasing the life of the implant and 2 times accelerate the rehabilitation of patients.
RECOMMENDED FIELD OF APPLICATION:
The efficiency of using bioactive glass-crystalline coatings for titanium alloys based on calcium-silicophosphate glass-crystal glasses in orthopedics and dentistry as bone tissue substitutes.
