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, 2001The 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, 2016Nowadays, 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.

Nanostructured Calcium Phosphate Coating for Stents
Key Engineering Materials, 2007A nanoporous calcium phosphate (CaP) coating on metallic surfaces is presented. The coating consists of a stack of (a) a TiNbN layer deposited by physical vapor deposition and acting as diffusion barrier against allergenic ions, (b) a SiO2 xerogel layer providing good adhesion properties and designing the nanoporosity of the outer CaP layer (c ...

Calcium phosphate coatings for orthopaedic prosthesis
Surface and Coatings Technology, 1991Abstract 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 ...

The Effect of Adjuvant Calcium Phosphate Coating on a Porous-Coated Femoral Stem
Clinical Orthopaedics & Related Research, 2004A prospective, randomized, double-blind, multicenter trial was done to determine if the addition of hydroxyapatite and tricalcium phosphate to the porous coating of a cementless femoral component would result in improved clinical and radiographic outcomes. Patients were randomized to receive identical porous-coated stems with (n = 159 hips) or without (

Calcium phosphate coatings are known to enhance long-term fixation, reliability and promote osteointegration of cementless titanium-based implant devices. This study was aimed at the pulsed laser deposition of calcium phosphate coatings onto titanium using hydroxyapatite and hydroxyapatite-fluorapatite targets.

Calcium Phosphate Coatings for Implant Fixation
2004It has been predicted that the number of revisions due to mechanical loosening after total hip replacement will increase steadily from year to year due to the increasing number of joint replacements. Unfortunately, results after revision arthroplasty are clearly inferior to those of primary arthroplasty (1).

Characterization of Thin Calcium Phosphate Coating
2008For the development and improvement of thin calcium phosphate (CaP) coatings, a thorough understanding of the compositional, structural, and mechanical aspects of the coatings is required. This chapter reports on the basic principles of the techniques and how to apply them for the characterization of (thin) CaP coatings.
