kinetic cavity preparation

The preparation of dental hard tissue, which includes enamel, dental dentin, and cementum, is mainly done with rotating instruments, the so-called drills, which are cooled by water. Nevertheless, the friction during the drilling process partially causes a warming to 250°Celsius. But even from 65°C on, proteins in the tooth are damaged, causing pain.

Alternative to the drill

An alternative to the conventional filling therapy with the drill is the kinetic cavity preparation (KCP). In this treatment, a focused stream of alumina powder (27 microns) is applied to the treatment area at an extremely high rate of acceleration without being touched by the nozzle.

This creates a small hole in the dental hard tissue, through which the caries infestation can be treated. Furthermore working with the kinetic cavity preparation is more accurate and finer than with a dental drill.

Advantages of KCP

In addition to more precise work, the kinetic cavity preparation offers further advantages. Anesthesia is often no longer needed during the treatment process, as there is no pain. Moreover, the treatment time is very short and there is no thermal damage to the tooth. Also, the enamel is roughened by the treatment, which is an ideal condition for the filling.

Especially for anxious patients and children, KCP is a good alternative to conventional restorative therapy because it eliminates the typical drill noise of rotating instruments altogether.
