Intended Use

The Rodo Smilekey is intended to be used with the Rodo Abutment System for removing prostheses compatible with Smileloc Sleeve by using induction heating.

Device Story

Rodo Smilekey is a handheld dental device used to remove prostheses from the Rodo Abutment System. It functions by delivering induction energy (alternating electromagnetic field) to the Smileloc Sleeve, which heats the sleeve to release the prosthesis. The device consists of a tip and a handle containing a rechargeable lithium battery and an electronic control board. The operator inserts only the tip into the patient's mouth; LED indicators on the handle signal when energy is being applied and when the unlocking procedure is complete. The device is used by dental professionals to facilitate the removal of dental restorations. By providing a controlled induction heating method, it allows for the safe release of the prosthesis while maintaining implant and abutment temperatures within established safety limits.

Clinical Evidence

No clinical data. Bench testing only. Testing included electrical safety (AAMI/ANSI ES60601-1), EMC (AAMI/ANSI/IEC 60601-1-2), biocompatibility (ISO 10993-1, ISO 10993-5), cleaning/disinfection validation, software verification/validation, battery testing (IEC 62133), usability (IEC 60601-1-6), and thermal safety (ASTM F2182-11). Thermal testing confirmed that implant/abutment temperatures during activation remain below established safety limits.

Technological Characteristics

Handheld device with tip and handle; rechargeable lithium-ion battery; induction heating principle (alternating electromagnetic field); LED status indicators; internal timer for energy regulation. Materials evaluated for biocompatibility per ISO 10993-1. Thermal safety validated per ASTM F2182-11. Software-controlled energy delivery.

Indications for Use

Indicated for use with the Rodo Abutment System to remove prostheses compatible with the Smileloc Sleeve via induction heating.

## Device Description

The Smilekey is an additional remover device intended for use with the predicate Rodo Abutment System (K160786). It is used to deliver induction energy to the Smileloc Sleeve. The Smilekey consists of a tip and handle that uses induction (alternating electromagnetic field) to deliver precise energy to the Smileloc. Only the end of the tip is inserted inside the patient's mouth while the handle is hand-held by the operator. The Smilekey is powered by a rechargeable lithium battery inside the handle. The handle also contains an electronic control board that regulates the entire operation, including LED indicators that let the operator know when energy is being applied to the Smileloc Sleeve and when the unlocking procedure has been completed.

## Substantial Equivalence

The proposed Rodo Smilekey and the predicate Smileloc Activator (part of the Rodo Abutment System K160786) have a similar intended use and similar indications of removing the Smileloc Sleeve from the Rodo Abutment. Both devices are intended to activate the Smileloc Sleeve to release a compatible prosthesis with the Rodo Abutment. Although the subject device uses induction heating instead of resistance heating, this difference in technological characteristics does not raise different questions of safety or effectiveness. Both devices deliver energy to increase the temperature of the Smileloc Sleeve. The induction energy is within safe levels for

{5}------------------------------------------------

the oral application. In addition, the performance of the Rodo Abutment System and the thermal safety was verified and validated using the same scientific methodology as the predicate device. In addition, bench testing of the subject device has demonstrated substantial equivalent performance to the predicate device.

# Conclusions

The Smilekey is an additional remover device intended for use with the predicate Rodo Abutment System (K160786). Similar to the predicate Smileloc Activator, the Smilekey uses heat to activate and to remove the Smileloc Sleeve. Although the Smilekey has a different heating method when compared to the Smileloc Activator, this difference in technological characteristics does not raise different questions of safety or effectiveness. Performance bench testing of the Smilekey demonstrated equivalent performance as the predicate device. Thus, the Smilekey can be found substantially equivalent to the predicate device.
