Brushite cements have been clinically used for irregular bone defect filling applications, and various strategies have been previously reported to modify and improve their physicochemical properties such as strength and injectability. However, strategies to address other limitations of brushite cements such as low radiopacity or acidity without negatively impacting mechanical strength have not yet been reported. In this study, we report the effect of substituting the beta-tricalcium phosphate reactant in brushite cement with baghdadite (Ca3ZrSi2O9), a bioactive zirconium-doped calcium silicate

Calcium phosphate fillers have been shown to increase cement osteoconductivity, but have caused drawbacks in cement properties. Hydroxyapatite and Brushite were introduced in an acrylic two-solution cement at varying concentrations. Novel composite bone cements were developed and characterized using rheology, injectability, and mechanical tests. It was hypothesized that the ample swelling time allowed by the premixed two-solution cement would enable thorough dispersion of the additives in the solutions, resulting in no detrimental effects after polymerization. The addition of Hydroxyapatite an

Bajpai et al. originally reported the formation of cements by the mixture of carboxylic acids and β-tricalcium phosphate (β-TCP). In the current study, we report and contrast four such cement systems formed from mixing citric, malic, 2-oxoglutaric or phosphoric acid with β-TCP. Cements formed from malic or 2-oxoglutaric appeared to contain crystalline phases and were determined to contain brushite, β-TCP and unreacted acid. In contrast, cement formed with citric acid was poorly crystalline, containing little evidence of brushite formation and was unstable in water and therefore does not appear

Brushite cement has advantages such as fast setting, high reactivity and good injectability over apatitic cements. To induce the bioactivity of brushite cements, the goal was to convert it into a bone-like low crystalline carbonate apatite. To achieve this induced transformation, potassium and magnesium were used as dopants which were claimed to be effective in the literature. The cements were immersed for 2 periods of time: 1 day and 6 weeks in Tas-Simulated-Body-Fluid (Tas-SBF) due to its excellent biomimetic properties with its adjusted HCO3- and Cl- ionic rates according to human-blood-pla

Boron-containing brushite cements (B-BC) for bone grafting based on B-substituted β-tricalcium phosphate (B-TCP) have been developed. The phase composition and microstructure of B-BC have been studied. It is shown that the crystalline phase of brushite is formed as a result of hardening of cements. The behavior of B-BC in physiological solution containing TRIS-buffer was studied. The strength of B-BC under compression 5 days after mixing is 22.5 ± 1 MPa. Studies of antibacterial activity against gram-negative strain E. coli ATCC25922 and gram-positive strain S. aureus ATCC25923 showed that bor

Apatite wollastonite glass ceramic (AW-GC) (34.2% SiO2, 44.9% CaO, 16.3%P2O5, 4.6% MgO, 0.5% CaF2) was added into a brushite bone cement, which composed of β-tricalcium phosphate (β-Ca3(PO4)2, β-TCP) and monocalcium phosphate monohydrate (Ca (H2PO4)2H2O, MCPM) in powder phases. Cement was prepared using a 3 β-TCP:2 MCPM in weight ratio. To evaluate the effect of AW-GC on the mechanical strength and degradability of brushite bone cement, the powder phases and 1 wt.% of chitosan dissolved in 5 wt.% of citric acid solution were mixed and soaked in simulated body fluid solution at 37 °C for 1, 3,

The hydrolysis of brushite in calcium phosphate cements to form hydroxyapatite is known to result in the long term stability of the material in the body. It has previously been established that this hydrolysis reaction can be influenced by implant volume, media refreshment rate and media composition. In this study, the effect of macroporosity on the rate of degradation of the material is investigated. Macroporosity was incorporated into the material using calcium alginate beads mixed into the cement paste. The inclusion of the calcium alginate beads did not influence the degree of conversion o

The effect of mechanical mixing on compressive strength, relative porosity and reliability of strength data of a brushite forming cement at different powder to liquid ratios (PLRs) was investigated. Mean compressive strengths were measured, associated reliability (Weibull moduli) and survival probability distributions of the data sets were analysed. Relative porosities were determined using helium pycnometry. For low PLR (2.2g/ml), no significant differences in compressive strength were observed for either mechanical or hand mixed samples, although reliability of the former was significantly i

Brushite cements have potential as drug carriers and bone filling materials. They can also act as a reservoir for calcium and phosphate ions in remineralisation of hard tissues. Aim and objectives: To optimize brushite cement properties and assess the effect of incorporation of a novel antimicrobial ε-polylysine (PLS) into brushite. Materials and Methods: Powders were mixed with aqueous solutions at a powder to liquid ratio of 3.3:1 or 4:1 to produce cement pastes and start the setting reaction. The powder consisted of 1g of monocalcium phosphate monohydrate (MCPM) and 1.23 g of β -tricalcium

Calcium phosphate cements are used in medicine to fill bone defects or give support to screws and plates in fracture fixation. The cements are formed via mixing a powder with water and the mixture harden through a dissolution-precipitation reaction. Today the cement mixing is performed in the operating room and consists of several complicated steps that need to be performed under sterile conditions. This renders the mixing a risk factor, potentially leading to harm for the patient e.g. unsatisfactory healing or infection. To reduce this risk, premixed cements have been developed using glycerol

Calcium phosphate cements (CPCs) are used as bone void fillers and as complements to hardware in fracture fixation. The aim of this thesis was to investigate the possibilities and limitations of the CPCs’ mechanical properties, and find out if these ceramic bone cements can carry application-specific loads, alone or as part of a construct. Recently developed experimental brushite and apatite cements were found to have a significantly higher strength in compression, tension and flexion compared to the commercially available CPCs chronOS™ Inject and Norian® SRS®.

In the field of Paediatric Dentistry, brushite cement has potential as an endodontic medicament and bone substitute material. Clinical applications however are limited due to their inherent properties, such as rapid setting time and poor mechanical properties. Antimicrobial e.g. chlorhexidine (CHX) could be incorporated into the cement for localised drug release. Aim and objectives: The aim of this study was to assess if partial replacement of citric acid (CA) by polyacrylic acid (PAA) can improve the properties of conventional brushite cements.

In this chapter, besides its biomedical applications, the synthesis and properties of brushite were investigated. Brushite consists of two types of crystals, platy and needle-like, and their formation depends on the pH of the medium during precipitation. Platy crystals are formed in a slightly acidic medium, pH = 5, and needle-like crystals at a higher pH = 6.5–7. In this study, the monoclinic brushite crystals were synthesized using dissolution-precipitation reactions. It is found that the brushite crystal growth occurs mainly along the (020) crystallographic plane. The thermogravimetric anal
