DEVICE DESCRIPTION AND COMPARISON TO PREDICATE PRODUCTS The Siemens T1 CONTROL high speed dental handpiece is intended for use in the dental operatory to prepare dental cavities for restorations, such as fillings. The device is an air-powered, high speed handpiece constructed of titanium. The device is reusable, is ergonomically shaped, and includes a solid fibre optic rod built-in light system. The water delivery geometry includes three spray nozzles in the device head with one-way retraction valves to prevent the ingress of external air or liquid when the spray system is shut down. The device can be sterilized by the steam autoclave method. The Siemens T1 CONTROL high-speed dental handpiece is similar in design, function, and intended use to other high-speed dental handpieces currently in U.S. commercial distribution. Examples of substantially equivalent devices include the Tradition high-speed handpiece manufactured by Midwest (K863677), the Star Dental 430 series high-speed handpiece manufactured by DEN-TAL-EZ, Inc. (K960719), and the W&H 898 Top Light high-speed handpiece manufactured by A-DEC, Inc. (K944710). ## 7. PERFORMANCE TESTING The Siemens T1 CONTROL Dental Handpiece complies with ISO Standard 7785-1 for High Speed Air Turbine Handpieces, ISO Standard 1797 for Dental Rotary Instruments - Shanks, and ISO Standard 9168 for Dental Handpieces - Hose Connectors.
