Intended Use

The OPTIMA MX is intended for use in dentistry for restoration, phophylaxis and endodontic procedures. It provides control for motorized dental handpieces by converting pneumatic output from a dental treatment center.

Device Story

Optima MX is a dental unit component system comprising a control unit, power supply, hose, and brushless micromotor. It functions by converting pneumatic output from a dental treatment center into electrical energy to drive motorized dental handpieces. The control unit is programmable, allowing the operator to adjust torque, speed (100–40,000 rpm), and rotation direction (clockwise/counterclockwise). Inputs are provided via a color touchscreen on the control unit or through the treatment center's foot pedal. The device is used in clinical dental settings by dental professionals to facilitate restorative, prophylactic, and endodontic procedures. By providing precise control over handpiece speed and torque, the device assists the clinician in performing dental tasks, potentially improving procedural efficiency and patient outcomes.

Clinical Evidence

Bench testing only. Performance evaluations compared the Optima MX to the predicate device (SiroTorque L) regarding rotational speed and torque measurements. Results indicated comparable performance, with the Optima MX showing slightly better control at lower speeds. Torque curves for both devices exhibited similar trends, with minor deviations from theoretical curves in the upper and lower ranges. Electrical safety and electromagnetic compatibility testing were also conducted in accordance with consensus standards.

Technological Characteristics

System includes control unit, power supply, hose, and brushless micromotor. Features 4-quadrant speed control (100–40,000 rpm), variable intensity lighting, and clockwise/counterclockwise rotation. Operates by converting pneumatic output from dental treatment centers. Software functions were verified and validated. Testing conducted per consensus standards for electrical safety and electromagnetic compatibility.

Indications for Use

Indicated for use in dentistry for restoration, prophylaxis, and endodontic procedures requiring motorized dental handpieces.

Regulatory Classification

Identification

A dental operative unit and accessories is an AC-powered device that is intended to supply power to and serve as a base for other dental devices, such as a dental handpiece, a dental operating light, an air or water syringe unit, and oral cavity evacuator, a suction operative unit, and other dental devices and accessories. The device may be attached to a dental chair.

#### PERFORMANCE TESTING 15.7

Performance testing of the OPTIMA MX was conducted to evaluate the rotational speed and torque measurements of the device. This testing was done in comparison to the predicate device, the SiroTorque. Results of the testing showed that the both devices had good control of speed with the OPTIMA MX being slightly better at lower speeds. Torque curves were developed for the tow devices and they were found to share a similar trend. Compared to the theoretical curve, both devices showed a slightly lower torque in the upper range and slightly more torque in the lower range.

## 15.8 CONCLUSIONS

This notification contains all information required by 21 CFR 807.87. A completed copy of the Premarket Notification 510(k) Reviewer's Checklist is provided in this submission. Performance and software evaluations of the OPTIMA MX show that the device performs as intended. Comparison of the OPTIMA MX to the predicate device show that the device is substantially equivalent.

The OPTIMA MX is substantially equivalent to the SiroTorque L based on equivalence of the intended uses, comparison testing and technical characteristics. The OPTIMA MX and the SiroTorque were comparison tested for rotational speed and torque measurement. Both devices were shown to be comparable in speed and torque values.
