Comparative Study Of The Mechanical Characteristics Of Dental Implants Made From Biomaterials Covered With DLC Depositions

Abstract

Nanostructures and nanostructured materials development has opened important expectative in multiple fields, however, one of them, with important direct impact on the society is the medicine. In this paper is presented a comparative study of the mechanical properties of titanium used for dental implants covered or not with an ultra thin DLC (Diamond Like Carbon) film deposition. Evaluation was focused on determining the number of cycles until failure in dynamic fatigue testing according to SR EN ISO 14801: 2008 and static compression strength according to SR EN ISO 6892-1:2010, for dental implants made of pure titanium covered/not covered with a layer of DLC. In order to make a comparison between covered and uncovered specimens, two of them were covered with DLC depositions, and other two without deposition. The obtained results show the improvement of the mechanical properties.
