Method and product for phosphosilicate slurry for use in dentistry and related bone cements

A method of preparing a mixture for forming a ceramic material for use in dental and orthopedic applications, said method comprising the steps of:

• providing a substantially dry powder component, said dry powder component comprising from about 5 percent to about 15 percent by weight of a sparsely soluble oxide powder, from about 15 percent to about 45 percent by weight of an alkali metal phosphate powder, from about 15 percent to about 35 percent by weight of a sparsely soluble silicate powder, the balance of the substantially dry powder component comprising at least one powder selected from the group consisting of bioactive powders, biocompatible powders, fluorescent powders, fluoride releasing powders, and radiopaque powders, said substantially dry powder component comprising about 65 percent to about 85 percent by weight of the mixture formed when the substantially dry component is combined with a liquid component;
• providing a liquid component, said liquid component comprising from about 0 percent to about 20 percent by weight of a pH modifying agent, and from about 0 percent to about 50 percent of a monovalent alkali metal phosphate in aqueous solution, the balance being water;
• and
• mixing the substantially dry powder component with the liquid component to form a paste.
