摘要：Introduction: with the in crease in bone structure problems resulting from accidents and many other inflammatory processes or diseases related to human aging, studies are needed to improve materials or create new materials. Objective: This study carried out a bibliographical survey on hydroxyapatite bioceramics. Results and Discussion: it was found that this material is made of calcium phosphate and has a composition similar to that of bone matrix, being promising in several applications in the area of biotechnology, having excellent properties, such as biocompatibility, osteoconductivity and bioactivity. Synthesis routes are one of the precursors of its favorable characteristics for different cientific and technological application areas, such as drug release, the matrix is capable of adsorbing hydrophilic and hydrophobic substances; application of implants due to the size and morphology of the pores that allow the passage of bloodstream; in dentistry used in various functions such asto neutralize dentinal hypersensitivity, but also to repair enamel and prevent caries. Conclusion: it appears that HA is of great interest for technological innovations, bringing advances in bioengineering and improving existing applications.
