Abstract: 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.

Abstract: Combining nanosized particles of a source of desired dental restorative, repair or therapeutic materials with strengthening agents in various generally nanosized form such as whiskers, fibers, particles and the like in a resin matrix provides a highly strain resistant composite which more effectively releases the therapeutic agents. The utilization of nano sized particles of the therapeutic agent in the combination enables observation of significantly improved therapeutic results.

Abstract: A method for preparing uniquely sized nanoparticles of CaF 2 by simultaneously spray drying a first NH 4 F and a biocompatible salt solution and a second Ca(OH) 2 and biocompatible salt solution to form CaF 2 solid particles in a soluble salt matrix wherein the salt is more soluble than CaF 2 . The salt matrix may then be dissolved and the separate CaF 2 nanosized particles collected for use as a dental therapeutic material. The technique is useful in the preparation of other discrete, nanoparticle sized compounds and combinations by carefully choosing the solvents and solutes of the two spray dried solutions.
Abstract translation: 通过同时喷雾干燥第一NH 4 F和生物相容性盐溶液和第二种Ca（OH）2和生物相容性盐溶液以在可溶性盐基质中形成CaF 2固体颗粒，其中所述盐的溶解度比 氟化钙。 然后可以将盐基质溶解并收集单独的CaF 2纳米尺寸颗粒以用作牙科治疗材料。 该技术通过仔细选择两种喷雾干燥溶液的溶剂和溶质来制备其它离散的纳米颗粒大小的化合物和组合是有用的。
