Osteoclast Response to Bioactive Surface Modification of Hydroxyapatite
The aim of this study was to evaluate the in vitro response of osteoclast-like cells (RAW 264.7 cells) to a bioactive hydroxyapatite (HAP) surface that was modified using the 30% phosphoric acid-etching procedure reported in our previous paper (2013). The cells on the bioactive HAP surface were multinucleated and were larger than those on the untreated HAP surface. The cell occupancies were gre...
متن کاملBioactive Surface Modification of Hydroxyapatite
The purpose of this study was to establish an acid-etching procedure for altering the Ca/P ratio of the nanostructured surface of hydroxyapatite (HAP) by using surface chemical and morphological analyses (XPS, XRD, SEM, surface roughness, and wettability) and to evaluate the in vitro response of osteoblast-like cells (MC3T3-E1 cells) to the modified surfaces. This study utilized HAP and HAP tre...
متن کاملLaser surface modification of hydroxyapatite and glass-reinforced hydroxyapatite.
Surface treatment of materials with excimer laser radiation often results in the formation of a rough columnar or cone-shaped surface topography, which leads to a considerable increase in the surface area. As a result, the search for a non-porous bioactive material with adequate mechanical properties and a high surface to volume ratio, similar to porous materials, which could be used for drug d...
متن کاملLaser surface modification of 316 L stainless steel with bioactive hydroxyapatite.
Laser-engineered net shaping (LENS™), a commercial additive manufacturing process, was used to modify the surfaces of 316 L stainless steel with bioactive hydroxyapatite (HAP). The modified surfaces were characterized in terms of their microstructure, hardness and apatite forming ability. The results showed that with increase in laser energy input from 32 J/mm(2) to 59 J/mm(2) the thickness of ...
متن کاملSurface modification for titanium implants by hydroxyapatite nanocomposite
Background: Titanium (Ti) implants are commonly coated with hydroxyapatite (HA). However, HA has some disadvantages such as brittleness, low tensile strength and fracture toughness. It is desirable to combine the excellent mechanical properties of ZrO2 and the chemical inertness of Al2O3 with respect to the purpose of this project which was coating Ti implants with HA-ZrO2-Al2O3 to modify the s...
