Investigation of structure formation in calciumsilicophosphate glass-ceramic coatings for dental implants

Abstract

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.
