(K123695) X-CUBE by Saeshin Precision Co., Ltd. (K092758) {4}------------------------------------------------ ## 5. Description: The Ki-20 is designed to use in dental surgery. It consists of an E-type motor (DC 28V Operation Motor), handpieces, a control box, a foot switch and other accessories. It is designed that the speed and direction of the handpiece can be controlled by the control box and the foot switch. The irrigation tube and the pump are used to supply the cooling water for the successful surgery. ### 8. Indications for Use For use in a wide range of dental procedures including: endodontic surgeries, such as drilling into the tooth canal, and general dentistry, such as removing carious material from the dentin. ### 9. Substantial Equivalence Discussion: Ki-20 is substantially equivalent to Endo E Class (K123608), TRAUS SIP10 (K123695) and X-CUBE (K092758). The following comparison table is presented to demonstrate substantial equivalence. Ki-20 does not have a new intended use and it shows equivalent specifications with the predicate devices in most of parameters. The handpiece rotation speed of the subject device encompasses the subject device as well. Torque setting range applied to the motor of the subject device is different from the predicate device; however, it is within what was cleared in the reference devices. | | Candidate
