Changes in the Activity of Osteoblast Like Cells with Sol - Gel Derived Hydroxyapatite and Zirconia Nanocoatings
When producing implant materials, achievement of optimal bioactivity and biocompatibility are essential. Nanocoatings can provide an efficient cost effective way to alter the interactions of the implant material with its destined "host" environment. Nanocoatings of sol-gel derived carbonated hydroxyapatite (HAp) and zirconia were produced in this study. The surfaces were characterised by Fourie...
متن کاملHydroxyapatite coating on porous zirconia
Since hydroxyapatite has excellent biocompatibility and bone bonding ability, porous hydroxyapatite ceramics have been intensively studied. However, porous hydroxyapatite bodies are mechanically weak and brittle, which makes shaping and implantation difficult. One way to solve this problem is to introduce a strong porous network onto which hydroxyapatite coating is applied. In this study, porou...
متن کاملContaminant Resistant Sol-Gel Coatings
Valerie Rapson Greece Olympia High School Advisor: Kenneth L. Marshall University of Rochester Laboratory for Laser Energetics Summer High School Research Program 2005 1. Abstract Sol-gel coatings are used on the OMEGA laser optics as anti-reflection (AR) coatings to maximize their transmittance. Over time, trace organic compounds in the laser bay contaminate these sol-gel coatings, reducing th...
متن کاملDevelopment of porous chitosan-gelatin/hydroxyapatite composite scaffolds for hard tissue-engineering applications.
Composite scaffolds prepared from natural polymers and hydroxyapatite (HA) are expected to have enhanced osteoconductive properties and as a result gained much attention in recent years for use in bone tissue-engineering applications. Although there are various natural polymers available for this purpose, chitosan (C) and gelatin (G) are commonly studied because of their inherent properties. Th...
متن کاملOsteogenesis ability of CAD/CAM porous zirconia scaffolds enriched with nano-hydroxyapatite particles
BACKGROUND The aim of this study was to evaluate osteogenesis ability of CAD/CAM porous zirconia scaffolds enriched with hydroxy apatite used to augment large boney defects in a dog model. METHODS Surgical defects were made bilaterally on the lower jaw of 12 Beagle dogs. Cone beam CT images were used to create three dimensional images of the healed defects. Porous zirconia scaffolds were fabr...
