Intended Use

The ProDrive Replacement Turbine is intended for use by authorized persons in the practice of dentistry. The ProDrive Replacement Turbine is intended to be used intraorally by trained dental professionals for drilling and preparation of dental cavities for restoration, such as fillings.

Device Story

ProDrive Replacement Turbine is a high-speed air-powered turbine for existing dental handpieces. It utilizes a push-button spindle mechanism with unique geometry to grip ProDrive carbide and diamond cutting instruments. This mechanism locks the bur to prevent accidental disengagement and allows for an extended bur position to improve visibility and utility. The device is used by dental professionals in clinical settings. It is compatible only with ProDrive-specific burs, which feature a unique shank geometry. The turbine is constructed from stainless steel. It functions as a replacement component for refurbishing dental handpieces, providing improved performance and durability compared to standard friction-grip systems.

Clinical Evidence

Bench testing only. The device was evaluated against ISO 7785-1:1997(E) standards and FDA guidance for dental handpieces. Testing included extraction force, resistance to corrosion, torque, noise level, eccentricity, speed, air pressure, stall torque, and sterilization validation (250 cycles). Results indicate the device functions as well as or better than the predicate device.

Technological Characteristics

High-speed air-powered turbine; stainless steel construction; push-button spindle mechanism with unique geometry for proprietary bur locking; compatible with ProDrive carbide/diamond instruments; meets ISO 7785-1:1997(E) performance standards; sterilization validated for 250 cycles.

Indications for Use

Indicated for use by trained dental professionals for intraoral drilling and preparation of dental cavities for restoration, such as fillings.

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.

#### Description of Device:

The ProDrive Replacement Turbine is a high-speed air-powered turbine designed to be installed in existing, legally marketed dental handpieces.

The ProDrive Replacement Turbine is appropriate for use with ProDrive carbide and diamond cutting instruments. A push-button spindle mechanism is used to grip the shanks of the cutting instruments. The unique geometry of the bur shank and turbine spindle securely locks the bur in the turbine eliminating the slipping that can occur over time with traditional burs and turbines. In addition to improved performance and durability, the secure locking mechanism enhances the safety of the ProDrive Replacement Turbine by reducing the risk of accidental disengagement of burs from the handpiece during operation.

When fully seated, the length that the ProDrive bur extends from the handpiece is the same as that of the standard bur/turbine assembly. In addition, the ProDrive system incorporates the ability to index the bur to a second, extended, position effectively improving on the visibility angle and the utility of the handpiece without adversely affecting its performance.

Because of the unique geometry of the ProDrive Replacement Turbine it is appropriate for use only in combination with ProDrive carbide and diamond cutting instruments. Standard round-shank burs will not fit into the ProDrive chuck, preventing their unintended use. ProDrive burs, however, will fit in traditional friction-grip chucks and will meet appropriate performance requirements when used in this way.

With the exception of the unique drive-lock spindle, the ProDrive Replacement Turbine consists of commercially available replacement parts currently used to refurbish dental handpieces in the United States. The spindle is composed entirely of stainless steel. The predicate device spindle is also manufactured from stainless steel. Therefore, the products are considered to be identical in materials used in their manufacture.

ProDrive burs are composed of tungsten vanadium stainless steel, coated with carbide or diamond cutting surfaces. The ProDrive burs are machined for ProDrive Systems Inc. by the bur manufacturer to the unique shank geometry required by the ProDrive drive-lock mechanism. In all other respects the burs are identical to commercially available burs currently distributed in the

United States. The use of stainless steel in the manufacture of ProDrive spindles and burs ensures biocompatibility and resistance to corrosion.

The ProDrive Replacement Turbine meets or exceeds all of the applicable performances standards outlined in ISO 7785-1:1997(E). Extensive testing indicates that after 250 sterilization cycles the ProDrive Replacement Turbine continues to meet all performance requirements.

#### Intended Use of Device:

The ProDrive Replacement Turbine is intended for use by authorized persons in the practice of dentistry. The intended use of the ProDrive Replacement Turbine is identical to that of the Predicate Device.
