Abstract

This study describes the covering process of dental burs with CVD diamond and the quality of its cut during dental procedure proving, at the same time, its advantages in comparison to regular dental burs. Ten equals burs made of tungsten carbide (WC) were covered with CVD diamond trough Hot Filament Chemical Vapor Deposition technique (HFCVD), varying thickness and temperature of deposit, leaving constant the rest of the deposit parameters like pressure (50 mbar) and gas flow (H2 and CH4). Dental cuts were comparing in a standard cutting device. The burs as well as the cuts were analyzed trough Scanning Electron Microscope (SEM) and Energy Dispersive X-ray Analysis (EDX), what allow obtaining accurate measures of cuts and covering is chemical components. The quality and stress of the grown diamond was characterized by Raman analysis.
