Hydroxyapatite and Other Calcium Phosphates for the Conservation of Cultural Heritage: A Review

open access: yesMaterials, 2018
The present paper reviews the methods and the performance of in situ formation of calcium phosphates (CaP) for the conservation of materials belonging to cultural heritage. The core idea is to form CaP (ideally hydroxyapatite, HAP, the most stable CaP at

Biodegradable Cements for Bone Regeneration

open access: yesJournal of Functional Biomaterials, 2023
Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use.

Ionic Substitutions in Non-Apatitic Calcium Phosphates

open access: yesInternational Journal of Molecular Sciences, 2017
Calcium phosphate materials (CaPs) are similar to inorganic part of human mineralized tissues (i.e., bone, enamel, and dentin). Owing to their high biocompatibility, CaPs, mainly hydroxyapatite (HA), have been investigated for their use in various ...

Biomimetic Versus Sintered Calcium Phosphates: The In Vitro Behavior of Osteoblasts and Mesenchymal Stem Cells

open access: yesTissue Engineering. Part A, 2017
The fabrication of calcium phosphates using biomimetic routes, namely, precipitation processes at body temperature, results in distinct features compared to conventional sintered calcium phosphate ceramics, such as a high specific surface area (SSA) and ...
