Calcium phosphate coatings, obtained at different deposition rates by pulsed laser deposition with a Nd:YAG laser beam of 355 nm wavelength, were studied. The deposition rate was changed from 0.043 to 1.16 Å/shot by modification of only the ablated area, maintaining the local fluence constant to perform the ablation process in similar local conditions. Characterization of the coatings was perfo...

Biometallic materials are widely used in medicine because of excellent mechanical properties. However, biometallic limited the application biomaterials due to their lack bioactivity. To solve this problem, a gradient bioceramic coating doped with diatomite (DE) was successfully fabricated on surface Ti6Al4V alloy by using broadband-laser cladding process improve bioactivity metal materials. As ...

Static defluoridation of high fluoride (10-12 ppm) water by sixteen different combinations of tricalcium phosphate (TCP), bone char (BC), hydroxyapatite (HAP), and related substances has been investigated. Defluoridation of 100 mL of the water by 300 mg of relatively insoluble phosphates is only 60-70 percent complete. Defluoridation is 30 percent more efficient, however, when a more soluble ph...

Exogenous ideal delivery system for biologically active molecules is under intensive investigation. In the present study it was aimed to test the availability of different calcium phosphate biomaterials (CPBs), hydroxyapatite (HA), beta tricalcium phosphate (TCP), and a combination of these (TCP+HA) as dental pulp capping systems on healing of dog dental pulp. Experimentally perforated dental p...

Due to a significant influence of strontium (Sr) on bone regeneration, Sr substituted β-tricalcium phosphate (Sr-TCP) cement is prepared and investigated by short- long-term time-resolved techniques. For short-term investigations, energy-dispersive X-ray diffraction, infrared spectroscopy, and, for the first time, terahertz time-domain spectroscopy techniques are applied. studies, angular dispe...

Calcium phosphate (CP) materials have been used extensively for bone replacement and augmentation due to their similarity to the mineral component of bone. In addition to being nontoxic, they are biocompatible, not recognized as foreign materials in vivo, and most importantly, exhibit osteoconductive behavior, being able to help in bone formation during healing. CPs form an intimate physicochem...

Calcium phosphate-based cements with enhanced regenerative potential are promising biomaterials for the healing of bone defects in procedures such as percutaneous vertebroplasty. With a view to the use of such cements for low load bearing applications such as sinus augmentation or filling extraction sites. However, the inclusion of certain species into bone cement formulations has the potential...

Calcium phosphate [single-phase hydroxyapatite (HA), single-phase tricalcium phosphate (TCP), and biphasic HA-TCP] nanowhiskers and/or powders were produced by using a novel microwave-assisted “combustion synthesis (auto ignition)/molten salt synthesis” hybrid route. This work is an example of our “synergistic processing” philosophy combining these three technologies while taking advantage of t...

Calcium phosphate (Ca-P) coatings on zirconia bone implants have a great potential to improve the osseointegration of already existing ceramic implants, owing to their bone-bonding ability and high osteoconductive characteristics. In our study, we have prepared three different kinds of Ca-P coatings, namely the octacalcium phosphate (OCP), hydroxyapatite (HAp) and β-tricalcium phosphate (β-TCP)...

Abstract: The focus of bone tissue engineering is on the new strategies for developing bioactive and resorbable scaffolds, which have become an alternative to treatment diseases trauma. β-tricalcium phosphate (β-TCP) considered has excellent osteoconductivity. In attempt achieve good densification β-TCP scaffold improve its biological properties, it arises possibility combining this material wi...
