Abstract. Biocompatible calcium silicophosphate glassceramic coatings for titanium on the base of glasses in R 2 О-RO-RO 2 -R 2 O 3 -P 2 O 5 -SiO 2 system have been obtained. The influence of crystallization ability and roughness of experimental coatings on their surface free energy has been established. The use of titanium implants with applied apatite-containing glass-ceramic coating will significantly increase biocompatibility of the prosthetic implant and will reduce the time of its union with the bone.
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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
