No
The device is a physical dental handpiece with mechanical components (gears, motor connection, fiberoptics, water spray) and is not solely software. While it incorporates RFID technology, this is a hardware component for tracking and not the primary function of the device.
Based on the provided information, the Star E900 Handpiece Series is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use clearly states the handpieces are for general dentistry procedures performed on the patient (removal of decayed matter, cavity and crown preparations, etc.). IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening.
- Device Description: The description details a mechanical device used for physical manipulation within the oral cavity. It does not describe any components or functions related to analyzing biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing samples, reagents, or any other elements typically associated with IVD devices.
The device is a dental handpiece used for mechanical procedures, not for diagnostic testing of biological samples.

Device Description
The Star E900 Handpiece Series are reusable contra-angle handpieces, driven by an ISO 3964 compliant electric micro-motor or air driven motor, that are intended for use by trained dental professionals in the field of general dentistry. The Star E900 1:5, 1:1 and 5:1 handpieces are designed for general applications to prepare dental cavities for restoration. The Star E900 1:1 Straight Handpiece is designed for prophylaxis treatment, crown preparations, polishing finishing of tooth and restoration surfaces.
The Star E900 Handpiece Series feature an ISO 3964 compliant handpiece coupling connecting them to an electric micro-motor controlled by an electric control unit or air driven motor connected to a dental delivery unit. The control unit or delivery unit supplies energy to the handpiece which powers the gears within the handpieces. Depending on the applications, the handpieces have a maximum drive speed of 8,000 to 200,000 RPM's.
These handpieces are ergonomically shaped and have glass rod fiberoptics to illuminate the oral cavity during procedures. In addition, the handpieces have multi-port water spray. The exception to the fiber optics and water spray features is the Star E900 1:1 Straight Handpiece. This handpiece does not contain any fiberoptics nor does it have water spray capabilities.
All the handpieces in the Star E900 Handpiece series are composed of stainless steel and PEEK. They can be autoclaved.
The Star E900 Handpieces use only burs with hardened, tempered steel shanks or carbide shanks which are ISO 1797 compliant.
All handpieces in this series incorporate RFID (radio frequency identification) technology. This passive RFID tag does not have a built-in energy source. The RFID tag will allow the practitioner to track the device within the office only if the practitioner has a separate reader. The RFID reader will enable the practitioner to track such things as usage and maintenance.
The handpieces, with the exception of the Star E900 1:1 Straight Handpiece, incorporate a temperature sensor to be used in the service of the device, by trained service personnel, to access excessive heat in the handpiece, indicative of mechanical failure. This feature is not accessible to the practitioner.

Summary of Performance Studies
The bench tests per the following standards were conducted to evaluate the functional performance and safety of the Star E900 Handpiece Series:
- ISO 14457: 2017 Dentistry - Handpieces and Motors
- IEC 60601-1: 2020, Consolidated Version: Medical Electrical Equipment Part 1: General • requirements for basic safety and essential performance
The results of the bench testing verify that the Star E900 Handpiece Series conform to the requirements of ISO 14457:2012 and IEC 60601-1:2020 and demonstrate substantial equivalence to the predicate devices
Biocompatibility testing was not conducted on the materials used in the Star E900 Handpiece Series. However, an assessment as conducted per the FDA guidance "Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process." The materials used in the subject device are identical to those used in the reference device, K192412, where biocompatibility testing was conducted and leveraged from.
Sterilization validation for the handpieces was performed in accordance to ANSI/AAMI ST79:2010 & A4:2013, AAMI/ANSI/ISO 14937:2009 and ANSI/AAMI ST81:2004 (R2010). Cleaning and disinfection validation was conducted per the FDA Guidance Document for "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling" issued on March 17, 2015.
A risk management plan to identify any risks and the management of those risks was carried out during the design and development of the handpiece series. A risk analysis for the Star E900 Handpiece Series was conducted in accordance with ISO14971:2012. The analysis showed that the level of risk associated with the Star E900 Handpiece Series is not any greater than the level of risk associated with similar medical devices currently on the market.

VIII. PERFORMANCE DATA
The bench tests per the following standards were conducted to evaluate the functional performance and safety of the Star E900 Handpiece Series:
- ISO 14457: 2017 Dentistry - Handpieces and Motors
- IEC 60601-1: 2020, Consolidated Version: Medical Electrical Equipment Part 1: General ● requirements for basic safety and essential performance
The results of the bench testing verify that the Star E900 Handpiece Series conform to the requirements of ISO 14457:2012 and IEC 60601-1:2020 and demonstrate substantial equivalence to the predicate devices
Biocompatibility testing was not conducted on the materials used in the Star E900 Handpiece Series. However, an assessment as conducted per the FDA guidance "Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process." The materials used in the subject device are identical to those used in the reference device, K192412, where biocompatibility testing was conducted and leveraged from.
Sterilization validation for the handpieces was performed in accordance to ANSI/AAMI ST79:2010 & A4:2013, AAMI/ANSI/ISO 14937:2009 and ANSI/AAMI ST81:2004 (R2010). Cleaning and disinfection validation was conducted per the FDA Guidance Document for "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling" issued on March 17, 2015.
A risk management plan to identify any risks and the management of those risks was carried out during the design and development of the handpiece series. A risk analysis for the Star E900 Handpiece Series was conducted in accordance with ISO14971:2012. The analysis showed that the level of risk associated with the Star E900 Handpiece Series is not any greater than the level of risk associated with similar medical devices currently on the market.
IX. CONCLUSION
