Magnesium substitution in brushite cements
Materials Science and Engineering C, 2013The use of magnesium-doped ceramics has been described to modify brushite cements and improve their biological behavior. However, few studies have analyzed the efficiency of this approach to induce magnesium substitution in brushite crystals. Mg-doped ceramics composed of Mg-substituted β-TCP, stanfieldite and/or farringtonite were reacted with primary

Brushite–collagen composites for bone regeneration
Acta Biomaterialia, 2008Brushite-based biomaterials are of special interest in bone regeneration due to their biocompatibility and biodegradability; on the other hand, collagen is a well-known osteoconductive biomaterial. In the present study a new brushite-collagen composite biomaterial is reported.

Mechanical characterization of brushite and hydroxyapatite cements
Biomaterials, 2001Compression, tension and torsion tests were designed and completed successfully on a brushite and a precipitated hydroxyapatite cement in moist condition. Elastic and strength properties were measured for these three loading cases. For each cement, the full set of strength data was fitted to an isotropic Tsai-Wu criterion and the associated ...

Dicalcium phosphate cements: Brushite and monetite
Acta Biomaterialia, 2012Dicalcium phosphate cements were developed two decades ago and ever since there has been a substantial growth in research into improving their properties in order to satisfy the requirements needed for several clinical applications. The present paper presents an overview of the rapidly expanding research field of the two main dicalcium phosphate ...

Biochemical and Physicochemical Presentations of Patients With Brushite Stones
Journal of Urology, 2004We determined whether the biochemical and physicochemical backgrounds of patients with brushite stones differ from those with hydroxyapatite and calcium oxalate stones.From a computer data base of patients completing ambulatory evaluation 19 with brushite stones, 24 with hydroxyapatite stones and 762 with calcium oxalate stones were identified with the

Proton mobilities in brushite and brushite/polymer composites
Solid State Ionics, 1997Abstract This study reports various analyses of the proton activity in brushite CaHPO4·2H2O and monetite CaHPO4 considered as potential solid electrolytes in mineral/polymer composites. Volta battery devices are first used to control the migration paths of protonic species through phosphate pellets or brushite/polymer composites.

Clinical Implications of Brushite Calculi
Journal of Urology, 1991The clinical history of 30 patients with a total of 46 proved brushite urinary calculi was reviewed. The patients were active metabolically with 87% having a history of multiple calculi. Of the brushite stones 61% appeared hyperdense on x-ray but they had no consistent shape.

Thermal reactions of brushite cements
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2007AbstractThe thermal reactions of a brushite cement made of β‐tricalcium phosphate (β‐TCP), monocalcium phosphate monohydrate (MCPM), and an aqueous solution were followed in situ with an isothermal calorimeter at 37°C. The investigated parameters were the β‐TCP/MCPM weight ratio, the liquid‐to‐powder ratio, the synthesis route and milling duration of ...
