Development of glass ceramic coatings containing hydroxyapatite

Glass ceramic composites — to be used for coatings on titanium implants — based on leucite glass with elevated flux content and added hydroxyapatite or a mixture of hydroxyapatite and fluorite are examined. It is established that pastes containing no more than 30% hydroxyapatite in leucite glass are the best materials for denture coatings. Pastes with a higher content of hydroxyapatite Ca₁₀(PO₄)₆(OH)₂(> 30%) are recommended for coatings on intramaxillary titanium implants. __________ Translated from Steklo i Keramika, No. 4, pp. 34–36, April, 2007.
