Intended Use

The Avant handpiece will be used by dentists to remove decayed tooth structure, and to cut or alter the shape of teeth so they may be restored to form and function.

Device Story

Avant High Speed Handpiece is a handheld, air-powered dental instrument (132mm long) used by dentists to remove decayed tooth structure and shape teeth for restoration. Device connects to standard dental unit air/water hoses; compressed air (32-40 psi) drives an internal turbine at ~375,000 rpm. Internal channels deliver air/water for cooling and cleaning; optional fiber optic light illuminates the operating field. Dental burs are secured via push-button chuck. Housing is constructed of medical-grade liquid crystal polymer (Vectra A530); internal turbine, connector, and tubes are metal. Device is non-sterile and requires cleaning, lubrication, and steam sterilization before use. Clinical benefit is the efficient removal of tooth structure and preparation for restorative procedures.

Clinical Evidence

No clinical data submitted. Bench testing only, including air pressure, biocompatibility, polymer material properties, extraction force, rotational speed, and sterility validation.

Technological Characteristics

High-speed dental handpiece; air-driven turbine (375,000 rpm); housing material: Vectra A530 liquid crystal polymer; metal internal components (turbine, connector, tubes); push-button bur chuck; optional fiber optic illumination; steam sterilizable; dimensions: 132mm length; powered by compressed air (32-40 psi).

Indications for Use

Indicated for use by dentists to remove decayed tooth structure and to cut or alter the shape of teeth for restoration of form and function.

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.

Device name:

Proprietary name: Avant™ High Speed Handpiece Common or usual name: High speed dental handpiece Classification name: Dental handpiece and accessories, Class 1, 21 CFR 872.4200

Legally marketed device for substantial equivalence comparison: Midwest Tradition P High Speed Handpiece (K963050) Manufactured by Dentsply Midwest, Des Plaines, IL

Description of the device:

The Avant is a high speed dental handpiece, 132 millimeters long, with a lightly textured finish for enhanced grip. It is a hand-held, channeled instrument that is powered by compressed air that is delivered through a hose to an air channel in the handpiece at 32-40 psi. This impels the turbine in the head of the handpiece to revolve at approximately 375.000 rpm. Other internal channels deliver air and water to the head for cleaning and cooling. The handpiece may contain, as an accessory, an optics device to light the area of operation. Any common dental bur for cutting (not supplied by Ora Innovations) is held in place in the handpiece head by a push-button chuck.

The Avant handpiece housing is constructed of a high temperature, medical grade liquid crystal polymer (Vectra® A530 by Ticona, Summit, NJ). There are three major parts which are made from metal: a standard turbine (supplied by a manufacturer of dental handpiece turbines), the threaded connector at the back end which attaches to the standard air/water hose in the dental unit, and the internal tubes that carry the chip air and water. These three parts are substantially equivalent to those in the predicate device.

Similar to the predicate device, the Avant handpiece must be cleaned and lubricated with a quality commercial dental handpiece cleaner/lubricant. It is supplied non-sterile, but must be sterilized before use, as with the predicate device. It will be packaged as a single unit or in multiples.

**CONFIDENTIAL**

Intended use of device:

The Avant handpiece will be used by dentists to remove decayed tooth structure, and to cut or alter the shape of teeth so they may be restored to form and function.

The following tests were derived from the American Dental Association guideline, ISO 7785-1 and G95-1/ISO-10993:

Air pressure Biocompatibility Polymer material Color Extraction force Rotational speed Sterility validation

The test reports, located in the Appendix of the 510(k) application, show that the Avant handpiece is safe and effective.

The Avant handpiece is similar to the predicate device in that they both perform the same functions in the same manner, directing air at high pressure to metal turbines which rotate dental cutting burs. Both devices have tubes which direct air and water to the head to clean and cool the area, and they both can be steam sterilized. In addition, they have the option of including an optical light feature.

The principal difference lies in the construction of the housing of the handpieces. The Avant head and handle are made from a high temperature, medical grade polymer that will retain dimensional stability and strength through multiple sterilization cycles. The head and handle of the predicate device are made of stainless steel.

Performance testing: Comparative performance testing and clinical evaluations are not submitted as part of this 510(k).
