BERMUDEZ GARCIA, Vanessa Sofía et al. Obtaining hydroxiapatite through biological residues for dental bone graft. Rev. Estomatol. Herediana [online]. 2021, vol.31, n.2, pp.111-116. ISSN 1019-4355.  http://dx.doi.org/10.20453/reh.v31i2.3971.

The objective of this literature review is to identify the different sources for obtaining hydroxyapatite (HAP) from natural residues in order to use it as dental bone grafts. Hydroxyapatite can be classified according to its sources of origin as synthetic or biological; Among the sources of biological origins we can find of animal origin, aquatic origin, coral origin, egg shell origin and plant origin. The different types of synthesis available in the literature are described for obtaining hydroxyapatite from each natural source and its behavior as a bone filling material. The natural sources for obtaining hydroxyapatite from organic waste reduce the environmental impact (bio-waste) in addition to having multiple properties that are biocompatible with human bone tissue.
