Abstract
In this study, Merwinite (MW), has been successfully prepared by a modified sol-gel method. Optimization in calcination temperature and mechanical milling resulted in a pure and nano-sized powder which characterized by means of (XRD), (SEM), (TEM) and (FT–IR). We hypothesized that nano-sized MW would mimic more efficiently the nanocrystal structure and function of natural bone apatite, owing to the higher surface area, compared to conventional micronsize MW. Mechanical grinding in a ceramic ball mill for 6 hours resulted in (MW) nanoparticles in the range of about 33- 55 nm. Conventional micron-size MW had been previously investigated by many researchers but it is obviously different from bone mineral in aspect of mimicking the mineral resorption process. Bone crystals of natural hydroxyapatite (NHA ) are in nano-size dimensions and possess very large surface area. In contrast micron-size particles with lower surface area lack the potency of homogeneous absorption by osteoclasts and miss the unique advantage of nanotechnology for bioactivity and resorbability. Hence, we used the unique advantage of nano- biotechnology to improve novel nano merwinite (NMW) particles as a good candidate for tissue regeneration whether as a peri - implant filling powder or in combination with other biomaterials as a composite scaffold.
