Exploitation of 3D-Microporous Architecture Surface of Titanium Implant as Local Drug Delivery System

Modified Titanium Implant as a Gateway to the Human Body: The Implant Mediated Drug Delivery System

The aim of this study was to investigate the efficacy of a proposed new implant mediated drug delivery system (IMDDS) in rabbits. The drug delivery system is applied through a modified titanium implant that is configured to be implanted into bone. The implant is hollow and has multiple microholes that can continuously deliver therapeutic agents into the systematic body. To examine the efficacy ...

Mechanics considerations for microporous titanium as an orthopedic implant material.

This article investigates mechanics issues related to potential use of a recently developed porous titanium (Ti) material for load-bearing implants. This material may have advantages over solid Ti of enhancing the bone-implant interface strength by promoting bone and soft tissue ingrowth and of reducing the bone-implant modulus mismatch, which can lead to stress shielding. Experimental data fro...

Biocompatability of hydroxyapatite composite as a local drug delivery system.

PURPOSE To investigate the biocompatibility of hydroxyapatite composite (hydroxyapatite, plaster of Paris, and chitosan) impregnated with gentamicin, fosfomycin, imipenem, or amphotericin B. METHODS The interactions of the extract from each drug against osteoblast were tested using the methylthiotetrazole test. RESULTS Extracts from all drugs showed good biocompatibility at concentrations v...

vancomycin loaded chitosan beads as a drug delivery system for local antibiotic delivery in some infections

Synthesis of Mesoporous Silica and Modified as a Drug Delivery System of Ibuprofen

In this work we synthesized of mesoporous silica nanoparticles and functionalized with 3-aminopropyltriethoxysilane to improve the loading and release of ibuprofen bonded to 3-aminopropyltriethoxysilane. sample were characterized by Fourier transform infrared spectroscopy, Scanning electron microscopy , X-ray diffraction, and ultraviolet-visible. the Fourier transform infrared spectroscopy resu...
