Disclosed herein is a method for forming an anti-microbial layer on an apparatus. Also disclosed is a method for improving the anti-bacterial properties of a titanium device coated with titanium-nitride (TiN). Also disclosed is a medical apparatus comprising an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Quarternized titanium-nitride anti-bacterial coating for dental implants

In one aspect, the disclosure relates to protective, anti-bacterial coatings for medical implants and methods of making the same. Also disclosed herein are methods for improving the anti-bacterial properties of a medical device coated with silicon carbide (SiC) or titanium nitride (TiN). Further disclosed herein are medical devices including an anti-microbial layer prepared by the disclosed methods. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.

Methods and compositions for medical implants having anti-bacterial coatings

Dental prosthetic restoration coatings made of dielectric materials, methods of fabricating the same, as well as methods of testing dental prosthetic restorations are provided. A prosthetic restoration coating can include dielectric materials such as AlO, ZrO, SiNx, SiC, and SiO. Application can take place using plasma enhanced chemical vapor deposition (PECVD) methods, and alternating materials can be used to achieve desired anticorrosive, structural integrity, hardness, adhesion, and color characteristics. A testing method can include immersing a test device in solutions of differing pH, with or without abrasive steps. The cycling can include an acidic solution and a basic solution, with an optional neutral solution. As the abrasive step, a chewing simulator can be utilized.

Dielectric coatings for fixed and removable oral prosthetic restorations

Sol-gel processing techniques are used to produce alkali-free bioactive glass compositions based on SiO.sub.2, CaO and P.sub.2 O.sub.5. By varying the SiO.sub.2 content, a range of hydroxyapatite production rates can be obtained; conversely, varying the time of exposure to actual or simulated in vivo solutions permits use of a range of allowable proportions of SiO.sub.2. The sol-gel derived compositions can be chosen to achieve target values for thermal expansion coefficient, elastic modulus and volume electrical resistivity.
