  • Publication number: 20090028949
    Abstract: The present invention relates to a calcium phosphate-based formulation for bone filling, comprising at least one adjuvant giving adhesion properties, said at least one adjuvant can be selected from the sugar and sugar derivative group. The bone cement described in the present invention is characterised by adhesive and swelling properties particularly advantageous, improving dispersion of the biomaterial in the cavities to be filled and facilitating osteointegration.

  • Publication number: 20090028960
    Abstract: The present invention relates to a calcium phosphate-based formulation for bone filling, comprising at least one adjuvant giving adhesion properties, said at least one adjuvant can be selected from the saccharide head surfactant group. The bone cement described in the present invention is characterised by adhesive properties particularly advantageous facilitating the setting of the cement and offering a better containment of the bone-cement or bone-cement-prosthesis interface.

  • Patent number: 6923989
    Abstract: A method for preparing a calcium phosphate pasty material for injection which after, setting, is designed to form an apatite material consists in: producing from water and calcium phosphates pasty mixture capable of developing, hardening and forming a hydroxyapatite. The method is characterised in that it consists in adding to the calcic phosphates or to the pasty mixture before it is injected a methicone having relative to the mixture more than 0.30 wt. % and less than 10 wt. %. The resulting material can be injected, that is it can be transported in pasty form into a conduit under moderate pressure levels. The material sets on the site of implantation and hardens to form an apatite biomaterial in a manner similar to known methicone-free calcium phosphate mixtures.
