Antibacterial Activity and Bioactivity of Zn-Doped TiO2 Coating for Implants

چکیده
Lacking osseointegration and peri-implantitis induced by bacterial infiltration are the pivotal issues for long-term clinical success of implants. In order to improve bioactivity antibacterial properties implant materials, volcano-shaped microporous TiO2 coatings doped with Zinc (Zn) were fabricated via a micro-arc oxidation (MAO) method on pure titanium (Ti). The microstructure, morphology, chemical composition Zn-doped systematically studied. cell culture tests, formed promoted adhesion proliferation bone mesenchymal stem cells (BMSCs), exhibiting good biocompatibility. experiments revealed that Zn-TiO2 possess excellent against Staphylococcus aureus (S. aureus) Porphyromonas gingivalis (P. gingivalis).

Antibacterial PHAs coating for titanium implants
Biomaterial-associated infection is a serious complication of modern implantation surgery. Thus, the improvement of implant surfaces is required to avoid the first stage for biofilm formation, bacterial adhesion. The current research addresses this issue by developing drug delivery systems (DDS) consisting of antibiotic-loaded polyhydroxyalkanoates (PHAs) coatings on titanium implants. Dip-coat...
متن کاملAntibacterial Activity of As-Annealed TiO2 Nanotubes Doped with Ag Nanoparticles against Periodontal Pathogens
It is important to develop functional transmucosal implant surfaces that reduce the number of initially adhering bacteria and they need to be modified to improve the anti-bacterial performance. Commercially pure Ti sheets were anodized in an electrolyte containing ethylene glycol, distilled water and ammonium fluoride at room temperature to produce TiO2 nanotubes. These structures were then ann...
متن کاملSilver-Doped Nanoclay with Antibacterial Activity
The aim of this study was to synthesize Ag-nanoclay composite by solid ion exchange, then characterize, and evaluate the antibacterial activity. This newly introduced ion exchange is a simple and low cost technique, which provides a quicker method. Without chemical treatment, nanoclay was subjected to an ion exchange process in media containing molten salt of silver at 300 and 400 °C and at dif...

The application of Fe–TiO2 photocatalysis using sol–gel method by hot–dipping technique was investigated. Then, the influences of fabrication parameters, molar ratios of Fe to TiO2, the sol temperature, poly ethylene glycol (PEG) content and the number of dipping cycles on the photocatalytic activity in visible light region were mainly studied. The experimental results revealed the sample with ...
متن کاملIn vitro bioactivity of different degree of deacetylation chitosan, a potential coating material for titanium implants.
Clinical treatment of orthopaedic tissue injuries often involves the use of titanium and titanium alloys with considerable research focusing on the surface modification of these materials. Chitosan, the partly deacetylated form of chitin, is one of the materials under investigation as surface coating for orthopaedic implants in order to improve osteo-integration and cellular attachment. In this...
