A synthetic aragonite-based bioceramic: influence of process parameters on porosity and compressive strength

Calcite as a bone substitute. Comparison with hydroxyapatite and tricalcium phosphate with regard to the osteoblastic activity

“…Natural aragonite, mainly issued from coral, is frequently used though seldom studied [4], especially in maxillo-facial surgery, as a cement compound or implant. Although a synthetic aragonite powder does exist [5,6], the great difficulty of producing a volumic scaffold leads to the use of animal-origin aragonite (from coral). Therefore, persistent problems with this source require the solution of synthesizing pure calcite that is able to form a 3D implant, but few studies deal with a high purity synthetic crystalline form.…”

Investigation of the surface reactivity of a sol–gel derived glass in the ternary system SiO2–CaO–P2O5

“…Among biocompatible materials like calcium carbonate [1][2][3][4][5][6][7], calcium phosphate [8][9][10][11], aluminosilicate (geopolymers) [12][13][14] and Bioglass 1 [15][16][17], some of them, known as bioactive, are able to form an apatite-like layer on their surfaces when in contact with simulated body fluid (SBF) in vitro [18][19][20][21] or with physiological fluid in vivo [8,22,23]. This apatite-like layer, associated with bioreactivity [22], is speculated to be responsible for bone bonding [16,23].…”

Antibiotic cements in articular prostheses: current orthopaedic concepts

“…The use of AC is now currently accepted worldwide owing to its proven effectiveness in prophylaxis and its adjuvant role in infected cases. Research has improved our knowledge of AC treatments and the actions and limitations of local antibiotics, including the effect of local antibiotics in bioactive bone substitutes such as tricalcium sulphate [24][25][26], hydroxyapatite, calcium sulphate, calcium carbonate [27] and biodegradable sponges such as poly glycolic acid (PGA) and poly lactic acid (PLA).…”
