Intended Use

The Kreativ Mach 7 Air Abrasion system is used for cavity preparation in Classes I, III, III, IV, and V. The uses include removal of tooth structure and restorative dental materials, and site preparation for pit and fissure sealant therapy and bonding of porcelain and ceramic. It may also be used for restoration prophylaxis.

Device Story

Air abrasion pneumatic device; utilizes pressurized air and aluminum oxide powder to generate high-velocity particle stream; removes dental caries, old restorative materials, healthy enamel, and dentin; prepares tooth surfaces for adhesion. Operated by dental professionals in clinical settings via handpiece similar to high-speed dental drill. Features refillable particulate canisters for maintenance. Output is mechanical abrasion of tooth structure; enables restorative procedures and sealant preparation; benefits patient through minimally invasive tooth preparation.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Pneumatic air abrasion system; utilizes pressurized air and aluminum oxide abrasive powder; handpiece-based delivery; refillable particulate canisters; mechanical operation; no software or electronic components.

Indications for Use

Indicated for dental cavity preparation (Classes I-V), removal of tooth structure and restorative materials, site preparation for pit and fissure sealants, bonding of porcelain/ceramic, and restoration prophylaxis.

Regulatory Classification

Identification

An airbrush is an AC-powered device intended for use in conjunction with articulation paper. The device uses air-driven particles to roughen the surfaces of dental restorations. Uneven areas of the restorations are then identified by use of articulation paper.

Special Controls

The special control for this device is International Electrotechnical Commission's IEC 60601-1-AM2 (1995-03), Amendment 2, “Medical Electrical Equipment—Part 1: General Requirements for Safety.”

Device and indications for use:

The Mach 7 is an air abrasion pneumatic device which combines pressurized air and aluminum oxide powder to product a high velocity stream of particles to perform dental restorative procedures, including preparation for pit and fissure sealant and composite restorations.

The unit is capable of removing dental caries, old restorative materials as well as healthy enamel and dentin to prepare the tooth surface for subsequent adhesion of restorative materials. The abrasive particulate is delivered via a small hand piece which is approximately the size of a high speed dental drill.

The system is designed for ease of service and maintenance with readily accessed and refillable canisters for the particulate supply.

Discussion:

Since the intended use and technical specifications of the Mach 7 are virtually identical to the predicate devices and the differences in the device only make it easier to use, more reliable and more adaptable to a variety of dental practice situations, we believe that the Mach 7 is substantially equivalent to the predicate devices and can be marketed under Section 510 (k) of the FD&C Act.
