#### DEVICE DESCRIPTION 5.

The Sirona Implant Handpieces are handpieces with transmission ratios of 80:1 and 20:1. They can be driven by torque adjustable electrical motors for surgery treatments and air motors for general dental treatment. The Implant handpieces are attached to their drives via ISO 3964 coupling. A saline irrigation system for surgery treatment is integral to the Implant Handpieces. The head clamp accepts WB instruments complying with ISO 1797-1.

#### BASIS FOR SUBSTANTIAL EQUIVALENCE 6.

The overall design of the Sirona Implant Handpieces is similar to the design of the W & H WS-75 E/KM handpiece in that all of these devices allow the use of instruments complying with ISO 1797-1, the connection to motor via the standardized ISO 3964 coupling and offer a similar saline irrigation system.

Based on the comparison of intended use and technical features, Sirona Dental Systems believes that the Sirona Implant Handpieces are substantially equivalent to the predicate W & H Handpiece. The proposed and predicate devices have the same general intended use and principles of operation. The overall design of the proposed and predicate devices is similar.
