WEAR RESISTANCE AND BIOCOMPATIBILITY OF DENTAL TOOLS UPGRADED BY DIFFERENT COATINGS

Abstract

Dental tools are sometimes damaged as a results of exploitation or during sterilization and desinfection. The aim of durability improving of dental borers and tweezers and increasing of the biocompatibility was modification of the surface of tools by TiN and TiAlN coatings. The coatings were made by PAPVD technology (Plasma Assisted Physical Vapour Deposition). The dental borers and tweezers were observed after the operation time of 3, 6, 9, 12 and 24 months. The results of investigation are presented in this article.

Keywords: dental tools, TiN and TiAlN coatings, PAPVD method, metallographic observations, biocompatibility, wear resistance,
