Studies on calcium phosphate coatings

Surface and Coatings Technology, 2000
Hydroxyapatite, 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 ...

The influence of Sr content in calcium phosphate coatings

Materials Science and Engineering: C, 2015
In this study calcium phosphate coatings with different amounts of strontium (Sr) were prepared using a biomineralization method. The incorporation of Sr changed the composition and morphology of coatings from plate-like to sphere-like morphology.

Inhibition of mineralization by a calcium zirconium phosphate coating

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2008
AbstractBioactive ceramics used as coating materials combine the conductive properties of a bioceramic with the mechanical stability of the metal implant. We studied a calcium zirconium phosphate‐containing coating material, FA‐CZP [Ca5(PO4)3F, CaZr4(PO4)6], that is relatively insoluble in the biological milieu.

Platelet interactions with calcium-phosphate-coated surfaces

Biomaterials, 2005
Many 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 ...

[Degradation of electrodeposited calcium phosphate and calcium phosphate-chitosan coatings in vitro].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 2011
To investigate the degradation of electrodeposited calcium phosphate (ECP) coating and calcium phosphate/chitosan (ECPC) coating in vitro.Osteoclasts were isolated from neonatal rabbit long bone cavities and incubated with ECP and ECPC coatings. Calcium ion concentrations in the culture medium were analyzed at 3 days and 6 days.

The effect of calcium phosphate implant coating on osteoconduction

Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology, 2001
The purpose of this study was to determine whether a calcium phosphate (CaP) coating would have a significant impact on osteoconduction.In this investigation, porous-surfaced titanium alloy (Ti-6Al-4V) implants were prepared with or without the addition of a thin surface layer of CaP applied by means of sol-gel coating and implanted into the tibiae of ...

Bioactivity Assessment of Calcium Phosphate Coatings

Key Engineering Materials, 2016
Nowadays, bioactive coatings or modifications on titanium surface have been tested in vitro and in vivo. In this study, two types of calcium phosphate coatings were produced by a chemical deposition method and their bioactivity assay in cell culture medium were investigated.

Calcium phosphate coatings for orthopaedic prosthesis

Surface and Coatings Technology, 1991
Abstract An electrochemical method of deposition which consists of an induction of calcium phosphate precipitation on a titanium cathode is described. Several coatings have been made using this technique and have been characterized by physicochemical methods (infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, scanning ...
