Kinetic Preparation in Microscope Dentistry
Kotschy, Peter
The use of microscope dentistry for preparation procedures requires instruments that do not use water spray and do not interfere with the direct or indirect vision of the working field. Traditional preparation instruments such as diamond burs can produce microcracks in the tooth, which negatively affect the outcome, especially in the anterior region. For example, the edges of the teeth may crack or splinter during preparation. As a solution to these problems, this article demonstrates the use of the kinetic preparation technique with 27-µm aluminum oxide particles, which are blasted with varying pressure onto the tooth surface.
