In close cooperation with Dr. M. Oliver Ahlers, Hamburg, Komet® has developed sonic tips for the preparation of interproxi-mal cavities. The new sonic tips are | designed for the final shaping of cavities and for smoothing the interproximal cavity margins. The diamond coated working parts of the 4 new sonic tips are bisected lengthwise (mesial and distal), which makes them ideally suited for work on molars and premolars. To prevent damage to the adjacent tooth, the tips are only coated on one side. The popularity of ceramic restoration is constantly on the Increase. In order to create durable all-ceramic restorations of outstanding quality, certain rules have to be observed during the preparation of the recipient area prior to ceramic restorations. The shaping of the interproximal zone is particularly challenging. A slightly diverging, box-shaped preparation should be aspired, with right angles at the restoration margin. It Is therefore essential not to prepare acute angles and to avoid irregular margins and instable enamel structures. This is where the new sonic tips made by Komet come in. These tips were developed in line with the preparation guidelines for ceramic restorations, with a view to facilitating the shaping of the interproximal boxes. Thanks to their rounded angles in the transition area between the axial and the shoulder region, these sonic tips are capable of preparing the cavities to a perfectly chamfered shape, thus creating ideal conditions for taking a precise impression of the preparation, with either conventional impression material or by means of advanced radiographic techniques.
