Motor and Apex Module (MaAM)

The Motor and Apex Module (MaAM) is a control unit for dental procedures that operates up to three dental motors, an apex locator, and a peristaltic pump. The Midwest Power Lux motor drives straight and contra-angle handpieces for endodontic and general dentistry, while the Midwest Power Lux Implant motor is used for implant placement with sterile solution delivery. The apex locator helps dentists determine working length during root canal treatment.

The control module contains an internal component of a dental delivery system that receives electrical power from the delivery system and controls motor operation through delivery system instructions. The module supports manual apex locator use and combined use with motors. The same lip clip, file clamp, cable, and adapter components are shared between the proposed device and predicates for apex measurement, with two operational methods available: via file clamp alone or with a compatible contra-angle handpiece.

ISO 14457 for dental motors; IEC 62471:2006 for photobiological safety of lamps and lamp systems; ISO 3964:2018 AMD1:2018 for dental coupling dimensions.

The proposed device and predicate devices share identical technological characteristics, both providing a controller to operate electric micromotors for dental procedures by qualified practitioners. The control module is contained within the dental delivery system with the same power acquisition and user interface methods. The apex location technology uses the same established determination method evaluating electrical impedance, with identical shared components (lip clip, file clamp, cable). All testing demonstrated the proposed device meets specifications equivalent to the identified predicate devices.
