## Purpose of the Special 510(k) notice.

The Improved Comfort-Fit NightGuard is a modification to DenTek Oral Care Inc.'s Comfort Fit NightGuard (K072147).

## Intended Use

DenTek's Improved Comfort-Fit NightGuard is indicated for use for protection against bruxism or nighttime teeth grinding. It is intended to reduce damage to the teeth and to prevent the noise associated with bruxing or grinding.

### Technological Characteristics

The Improved Comfort-Fit NightGuard is a posterior-only occlusion nightguard, consisting of two bite pads connected by a buccal retention strap. The Improved Comfort-Fit consists entirely of ELVAX, a thermoplastic material. The bite pads move along the buccal strap in order to the individual user needs, with the strap always contained within the wings of the bite pads. There are 5 positions of adjustability for each molar pad.

#### Substantial Equivalence

DenTek's Improved Comfort-Fit has the same intended use and similar indications, principles of operation, and technological characteristics as DenTek's Comfort Fit.
