Amorphous Calcium Phosphate Coatings
2022Amorphous calcium phosphate (ACP) is unique among calcium phosphates because it lacks the long-range, periodic atomic-scale order observed in crystalline calcium phosphates. In addition, ACP exhibits a high dissolution rate in vitro and in vivo. In this chapter, the fabrication processes of ACP coating films, based on wet and dry processes, are ...

Dissolution Kinetics of Calcium Phosphate Coatings
Implant Dentistry, 1998Plasma spray and high velocity oxy-fuel (HVOF) techniques produce coatings with varying composition and amounts of amorphous and crystalline phases. For coatings containing greater amorphous phases, a higher release of calcium ions is evident when samples are placed in Hank's calcium-free balanced salt solutions.

Calcium phosphate coatings for medical implants
Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 1998In surgical disciplines where bone has to be repaired, augmented or improved, bone substitutes are essential. Although bone banks, such as Eurotransplant, are founded to supply such substitutes, natural bone is not always adequate. For example, frequently these so-called bone grafts resorb after implantation (1). Further, they cannot be used for joint

Biomimetic processing of calcium phosphate coating
Medical Engineering & Physics, 1998Most ceramics used in surgical implantation are better tolerated by the body environment than other biomaterials, particularly metals. However, the broader application of ceramics is limited because they are brittle and prone to catastrophic failure. By contrast.

Remineralization of demineralized albumin‐calcium phosphate coatings
Journal of Biomedical Materials Research Part A, 2003AbstractCalcium phosphate and bovine serum albumin were coprecipitated (under physiological conditions of temperature and pH) upon the surfaces of titanium‐alloy samples, which thereby became coated with a dense, proteinaceous mineral layer 30–50 μm in thickness.

Studies on calcium phosphate coatings
Surface and Coatings Technology, 2000Hydroxyapatite, one form of calcium phosphate, is preferred for its ability to interact with living bone, resulting in improvements of implant fixation and faster bone healing. The interlayer of nitrides or oxides formed by DC magnetron sputtering improved the bonding strength of plasma-sprayed hydroxyapatite coating to a maximum of 10 times for ...

Platelet interactions with calcium-phosphate-coated surfaces
Biomaterials, 2005Many studies have shown that calcium-phosphate (CaP)-coated endosseous implants exhibit more peri-implant bone formation and bone contact at early healing times than uncoated implants. Since the rate of healing is influenced by blood/implant interactions and possibly the degree of blood platelet activation, the aim of this study was to determine ...

Mechanical insertion properties of calcium‐phosphate implant coatings
Clinical Oral Implants Research, 2010AbstractObjectives: To investigate the influence of protein incorporation on the resistance of biomimetic calcium‐phosphate coatings to the shear forces that are generated during implant insertion.Materials and Methods: Thirty‐eight standard (5 × 13 mm) Osseotite® implants were coated biomimetically with a layer of calcium phosphate, which either ...
