There are various models of CVDentus tips already developed, and others will still be, depending on the necessities of the surgeon-dentists.

You know which is the best application of each one of these formats in dental cavity preparation, but it is necessary to clarify which are the best conditions of use of each one of the CVDentus tips.

The vibration of ultrasound is aggressive for the material of the connecting rod and for the interface between the CVD diamond and the connecting rod. It is even able to cause its rupture by fatigue.

The ultrasound power is the main parameter to be controlled to prevent this premature fatigue and to draw out the useful life of the tips. The amplitude of vibration due to ultrasound increases with the reduction of the cross section area of the material in which the ultrasound propagates. This implies that in tips of finer extremity the amplitude of vibration is bigger.

Based in this concept and the experience of use, the limiting power of use had been defined for each type of extremity of the active tip. This limit is described in terms of the percentage of the maximum power (Pmax) supplied by the ultrasound equipment. The majority of the equipments have the same range of maximum power (Pmax); therefore the table below shows the powers of use in a generic form.
