Dissolution and mineralization of sintered and thermally sprayed hydroxy-fluoroapatites.

摘要: Hydroxyapatites are commonly used as bone cement, coatings on implants for dental and orthopaedic applications, but also middle ear implants. These applications all require a different tissue healing response that can be attained by manufacturing processes or chemically modifying the composition. During implantation apatites undergo process of dissolution mineralization. The degree is dependent upon & higher thermally sprayed implant materials. This allows them to integrate natural bone. study tests mineralization fluoride containing hydroxyapatites through immersion in simulated body fluid. It shows occurs more readily than fluorapatites because their rate. Mineralization was detected most image analysis using scanning electron microscopy weight changes microbalance. Microscopy allowed small heterogeneous precipitates observed during initial stages
