Properties of Bioactive Glass Ceramic Coatings on Titanium alloys Obtained by Slip Technology

Abstract

1 Viability of developing bioactive glassceramic coatings on titanium alloys as dental implants with short terms of fusion with bone tissue has been substantiated. Features of formation of calcium silicophosphate glasses on initial stages of nucleation have been studied. It has been established that the presence of sybotaxic metaphosphate and hydroxide groups in glass melt and formation of crystalline phase nuclei through spinodal separation will allow formation of strengthened structure of vitreous material containing hydroxyapatite and fluorapatite in conditions of short-term lowtemperature thermal treatment. Developed glass-ceramic materials can be used as a base in obtaining resorptive strengthened glass-ceramic coatings on titanium alloys for dental implants.

Investigation of Structure Formation in Calciumsilicophosphate Glass-Ceramic Coatings for Dental Implants

“…Derived slips were applied by pouring onto specimens made of VT1-00 titanium alloy for use in medical equipment (ISO 5832/III) and dried at 353-393 K. Firing of the coatings was done in the temperature range of 1013-1023 K for 1-1.5 min. The indicated temperature regime allows to avoid active oxidation of titanium alloys with formation of brittle alpha case of significant thickness, as well as deformation of the item itself [14].…”

Effect of Low-Melting Glass on Thermal and Physical Properties of Polymer Composites

“…Biopowder closes the root canals, leaving phosphorus and calcium ions on its surface. Glass powder is an irreplaceable component of ionomer cements, which are used in the therapy and teeth prosthetics [7]. The main component of the Sensodyne toothpaste is bioglass powder.…”
