A calcium phosphate composition comprising calcium phosphate particles (A) and a sulfonic acid salt (B), wherein the calcium phosphate composition contains 0.5 to 20 parts by weight of the sulfonic acid salt (B) based on 100 parts by weight of the calcium phosphate particles (A) . This provides a calcium phosphate composition that has a time between the addition of a liquid agent to the calcium phosphate composition and the completion of setting in the use at a clinical site and the like, i.e., a setting time which is within an appropriate range and that is high in mechanical strength and good in marginal sealing ability.
L'invention porte sur une composition de phosphate de calcium comprenant des particules de phosphate de calcium (A) et un sel d'acide sulfonique (B), caractérisée par le fait que la teneur en sel d'acide sulfonique (B) est de 0,5 à 20 parties en poids pour 100 parties en poids des particules (A). Lorsqu'elle est utilisée dans un site clinique ou similaire, la composition présente un temps de durcissement (un temps nécessaire pour que la composition durcisse après l'addition d'un agent liquide) dans une plage appropriée, et peut former une masse durcie qui a des résistances mécaniques élevées et qui parvient à une excellente étanchéité périphérique.
