Deriving fast setting properties of tetracalcium phosphate/dicalcium phosphate anhydrous bone cement with nanocrystallites on the reactant surfaces

Fine-Tuning of Polymeric Resins and their Interfaces with Amorphous Calcium Phosphate. A Strategy for Designing Effective Remineralizing Dental Composites

“…Despite their multiple clinical applications, CPCs, even injectable types, still have drawbacks such as prolonged setting times, dispersion upon contact with blood or aqueous media and brittleness. One of the proposed ways for overcoming these drawbacks is by formulation of CPC/polymer composite cements [8, 9]. …”

Thermal cycling effect of dicalcium phosphate-reinforced composites on auto-mineralized dental resin

“…The nanocrystal formation was determined during the monitored treatment in accordance with previous studies [18,21]. DCPA powder (5 g) was mixed in 40 mL of solution (constant calcium-to-phosphate atomic ratio, 2.0; pH 5.0) for 20 min at room temperature.…”

“…The relatively limited amount of nanoCaP fillers (b30 wt.%) in composite resins is easily exhausted in the oral environment. Moreover, the fillers embedded in restorative matrix on the surfaces are difficult to expose [18][19][20][21]. The current research uses technology previously developed inhouse, which involves capping a layer of nanocrystals and salinization with resin matrix to form a composite resin [18].…”

Calcium phosphate bone cement with 10wt% platelet-rich plasma in vitro and in vivo

“…25 Developed CPC with a nanocrystallite treatment on the surfaces of powders had demonstrated excellent mechanical properties, and the same procedures were employed. 6 Briefly, the process for preparing the CPC for this study required soaking TTCP powder through a 3 M diammonium hydrogen phosphate ((NH 4 ) 2 HPO 4 ) solution for 5 min, which was then filtered and dried immediately. The powder was mechanically ground to the mean particle size distribution of CPC ($3 mm), vacuum-packed and g-ray-sterilized (20 kGy) (China Biotech Co., Taiwan).…”

“…In recent years, calcium phosphate bone fillers have been employed extensively orthopaedics, for example, with periodontal defect repair, as scaffolds for bone reconstruction, and in orthopaedics. [1][2][3][4][5][6] Because the main inorganic mineral components of bone and teeth are impure forms of hydroxyapatite (HA), the use of calcium phosphates for restorations leads to better osteoconductive properties compared with other commonly used biomaterials (for example, zirconia, alumina). [1][2][3][4][5][6] A suitable biomaterial for tissue engineering should support target cell growth and osteogenic differentiation.…”
