Komet has expanded its SonicLine instrument series with pair of Sonic tips for crown preparation, the SF856.000.018 and SF878K.000.018, corresponding with the company’s 856 (S6856.314.018) and 878K (S6878K.314.018) rotary crown-preparation diamonds, respectively. Sonic tip SF856.000.018 features a round tapered-chamfer configuration, while tip SF878K.000.018 provides a modified tapered-chamfer shape.
After supragingival preparation has been achieved with the diamond rotary instrument of matched shape, the corresponding Sonic tip is employed to produce a precisely positioned and finished prosthetic margin and to enhance interproximal finishing, Komet says. The tips create exceptionally fine crown margins that are essential to a well-fitting, durable restoration, according to the company.
While operating, the tips produce an oscillating function that allows the crown margin to be gently and safely positioned while protecting the soft tissue, preventing gingival trauma or hemorrhage that can compromise impressions. The oscillating elliptical vibrations of the tips also create an irregular surface structure of the crown core that promotes perfect penetration and adhesion for crown cementation.
The SonicLine system comprises a comprehensive range of tips that cover multiple indications, including prophylaxis, veneer procedures, and fissure openings as well as crown preparations. Special labeling enables users to easily identify the correct tip for a specific procedure. Laser etching of the order number on the tips facilitates new ordering as needs arise. The tips can withstand regular reprocessing in a washer or disinfector with a rinse adapter as well.
