Komet USA has added special sonic tips for the preparation of crown cores to its SonicLine sonic handpiece (SF1LM) system.
SonicLine tips are offered in six configurations (SF979.000.014 and 016, SF862.000.014, and SF847KR.000.016 and in fine-grain versions SF8979.000.014 and 016). After supragingival preparation has been achieved with Komet rotary instruments of matched shapes, the sonic tips are used to produce precisely positioned and finished prosthetic margins and to enhance interproximal finishing, according to the company.
Komet SonicLine sonic tips for crown preparation also include two special configurations. The working ends of these tips are half-coated lengthwise for applications on both mesial (SF8878KM.000.018) and distal (SF8878KD.000.018) surfaces. Precision-engineered to prevent damage to adjacent teeth, the halved tips are specially indicated for interproximal trimming.
When in operation, the Komet SonicLine crown-preparation tips produce an oscillating function that allows the crown margin to be gently and safely positioned while protecting the soft tissue, thus avoiding gingival trauma even in case of direct contact, according to the company. The oscillating elliptical vibrations of the sonic tips also create an irregular surface structure that promotes penetration and adhesion for crown cementation.
The SonicLine tips cover a multitude of indications, including prophylaxis, veneer procedures, and the opening of fissures, as well as crown preparation cases. Special tip labeling allows the user to identify the correct tip for a specific procedure, and laser etching of the order number on the sonic tips facilitates ordering of additional tips.
In addition, the tips can withstand regular reprocessing in a washer/disinfector through use of a rinse adapter, Komet noted.
