摘要： A bone or dental implant material in the form of a paste includes a mixture of calcium phosphate and/or calcium-containing powders, liquid glycerol, organic acid and gelling agent. The paste is stable, resistant to washout and will harden upon exposure to water. Physical characteristics of the paste, including consistency, porosity, and hardening time, are controlled by the choice and ratio of constituents.

摘要： Disclosed are endodontic filling materials and methods. A method for filling a dental root canal may include providing a hydrosetting filling material and inserting the hydrosetting filling material into the dental root canal, the material setting in the root canal to form a biocompatible filling. The hydrosetting filling material comprises a hydrogel former and a filler. The hydrogel former is at least one of a reactive organic hydrogel formers, an inorganic hydrogel formers, and a non-reactive organic hydrogel formers, and the filler is at least one of a self-hardening and a non-hardening filler. Plural filling material precursor compositions that collectively contain hydrogel formers and fillers may be provided.

摘要： Nano-particles of calcium and phosphorous compounds are made in a highly pure generally amorphous state by spray drying a weak acid solution of said compound and evaporating the liquid from the atomized spray in a heated column followed by collection of the precipitated particles. Hydroxyapatite (HA) particles formed by such apparatus and methods are examples of particle manufacture useful in bone and dental therapies. Dual nozzle spraying techniques are utilized for generally insoluble compounds.

摘要： A bone or dental implant material in the form of a paste includes a mixture of calcium phosphate and/or calcium-containing powders and a solution that is (1) an acidic calcium phosphate solution saturated with respect to one or more calcium phosphate compounds, (2) a concentrated acid solution, or (3) salt solutions with a cationic component other than calcium. The paste is stable, resistant to washout and will form hydroxyapatite and harden relatively rapidly to a cement.
