Intended Use

The Interproximal Reduction System is intended for use as a method of achieving interproximal reduction of teeth.

Device Story

The Interproximal Reduction System is an air-driven, low-speed dental handpiece with an integrated contra-angle head. It is designed for use by dental professionals in a clinical setting. The device operates by powering abrasive strips to perform interproximal reduction, stripping, polishing, or tooth preparation. By mechanically removing small amounts of enamel between teeth, the device creates space to facilitate the proper fitting of orthodontic appliances like aligners, brackets, and retainers. The clinician manually guides the handpiece to achieve the desired reduction, directly impacting the orthodontic treatment plan and patient dental alignment.

Clinical Evidence

Bench testing only.

Technological Characteristics

Air-driven low-speed motor with integrated contra-angle head. Mechanical actuation for abrasive strip operation. Standard dental handpiece form factor. No electronic or software components.

Indications for Use

Indicated for patients requiring interproximal reduction, stripping, polishing, or preparation of teeth for the placement of orthodontic appliances such as aligners, brackets, and retainers.

Regulatory Classification

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898.
