Indications for Use
The turbine handpiece is intended for the following applications: Removal of decayed materials, cavities and crown preparation, removal of fillings, finishing of tooth and restoration surfaces. The dental handpiece/contra-angle is intended for the following applications: Removal of decayed materials, cavities and crown cement, removal of fillings, finishing and polishing of tooth and restoration surfaces.
Device Story
Air-powered dental handpieces and attachments; used for tooth preparation, filling removal, and finishing/polishing. Device utilizes air-driven turbines or air motors to rotate burs; air and water pipes supply spray for cooling the working area and bur. Some models include integrated LED light systems powered by internal circuit boards. Operated by dental professionals in clinical settings. Output is mechanical rotation of dental burs for tissue/restoration removal. Benefits include efficient dental material removal and surface finishing. Device is reusable; requires cleaning and sterilization between patients.
Clinical Evidence
Bench testing only. Performance testing conducted per ISO 14457:2012 (function and life cycle), IEC 60601-1-2:2007 (EMC), and IEC 62471:2006 (photobiological safety). Biocompatibility evaluated via comparison to predicate materials and Cytotoxicity Testing per EN ISO 10993-5:2009, meeting ISO 7405:2008 requirements. No clinical data required.
Technological Characteristics
Reusable air-powered handpieces and attachments. Materials identical to predicates. Features include air-driven turbines/motors, air/water spray cooling, and optional LED illumination. Connectivity: pneumatic supply. Sterilization: dynamic-air-removal or gravity displacement autoclaves (132°C). Complies with ISO 14457, IEC 60601-1-2, IEC 62471, and ISO 10993-5.
Indications for Use
Indicated for dental patients requiring removal of decayed materials, cavity and crown preparation, removal of fillings, and finishing/polishing of tooth and restoration surfaces.
Regulatory Classification
Identification
A dental handpiece and accessories is an AC-powered, water-powered, air-powered, or belt-driven, hand-held device that may include a foot controller for regulation of speed and direction of rotation or a contra-angle attachment for difficult to reach areas intended to prepare dental cavities for restorations, such as fillings, and for cleaning teeth.
