CVD technology allows high adherence of the diamond as a unique stone on the metallic surface with excellent abrading performance.
CVD diamond burs become an option for cavity preparation,and preservation of tooth structure.
In 1996,CVD diamond burs coupled with an ultrasonic handpiece were introduced in dentistry to eliminate problems relate with diamond burs
CVD method produce high adherence between the diamond film and metal surface,induced by chemical bond
Because of the inherent roughness of the sharp edged and polycrystalline diamond layers,these tools are well suited for tooth grinding
They are obtained by chemical vapour deposition( CVD) of diamond film over a molybdenum substrate.
They were synthesized inside an enhanced hot filament assisted reactor.
This manufacturing process,and the adaptation to an ultrasonic handpiece,provide some potential advantage.
