Intended Use

Class I, III and V cavity preparation for caries removal Caries removal Hard tissue surface roughening or etching

Device Story

Millennium™ is a hydrokinetic tissue cutting system for dental applications. It utilizes an Er, Cr:YSGG solid-state laser to provide optical energy to atomized water droplets. The laser energy is absorbed by the water, causing micro-expansion and acceleration of the droplets, which mechanically ablate dental tissue. The device features a flexible fiberoptic handpiece with a visible aiming beam. The clinician adjusts optical power and water spray distribution. Used in dental clinics by professionals, the device provides a non-contact, non-thermal cutting mechanism. It is intended for cavity preparation, caries removal, and surface etching, offering a biocompatible cutting medium compared to traditional mechanical burs or abrasive systems.

Clinical Evidence

Evidence includes multi-phase in-vitro and in-vivo clinical trials on animals and humans. Studies utilized randomized, double-blinded clinical evaluations, pulp temperature studies, and scanning electron/optical microscopy to demonstrate safety and efficacy equivalent to predicate technologies.

Technological Characteristics

Er, Cr:YSGG solid-state laser; hydrokinetic cutting via atomized water droplets; non-contact operation. Materials: medical-grade plastics, steel, stainless steel, aluminum, brass. Power: 115/230 V, 50/60 Hz. Flexible fiberoptic handpiece with visible aiming light. Adjustable optical power and water spray flow.

Indications for Use

Indicated for Class I, III, and V cavity preparation, caries removal, and hard tissue surface roughening or etching in adults 18 years of age or older. Contraindicated for patients with specific medical conditions including allergy to local/topical anesthetics, heart disease, lung disease, bleeding disorders, sleep apnea, or immune system deficiency.

Regulatory Classification

Identification

## DEVICE DESCRIPTION:

The Millennium™ hydrokinetic tissue cutting system is a diverse instrument for performing several dental applications. Millennium™ utilizes advanced laser and water atomization technologies to ablate dental tissues safely and effectively. An erbium, chromium, yttrium, scandium, gallium garnet (Er, Cr:YSGG) solid state laser provides optical energy to a user controlled distribution of atomized water droplets. As the water droplets absorb the optical energy hydrokinetic cutting effects result.

The hydrokinetic process refers to the removal of tissues with high speed, atomized water particles. Strong absorption of laser energy by atomized water

{1}------------------------------------------------

droplets results in an intense yet controlled water particle micro-expansion and acceleration. The resulting hydrokinetic forces induce mechanical separation of surface material, yielding quick and clean mechanical tissue removal.

A flexible fiberoptic handpiece delivers the Millennium™s unique hydrokinetic tissue cutting technology. A visible light emitted from the handpiece distal end pinpoints the area of treatment. The optical power output and atomized water spray distribution may be adjusted to specific user requirements.

#### INDICATIONS FOR USE:

Class I, III and V cavity preparation for caries removal

Caries removal

Hard tissue surface roughening or etching

## CAUTIONS AND CONTRAINDICATIONS

All clinical procedures performed with Millennium ™ must be subjected to the same clinical judgement and care as with traditional techniques. Patient risk must always be considered and fully understood before clinical treatment. The clinician must completely understand the patient's medical history prior to treatment. Exercise caution for general medical conditions which might contraindicate a local procedure. Such conditions may include allergy to local or topical anesthetics, heart disease, lung disease, bleeding disorders, sleep apnea or an immune system deficiency. Medical clearance from patient's physician is advisable when doubt exists regarding treatment.

This device is to be used on adults over eighteen years of age only.

#### SUBSTANTIAL EQUIVALENCE:

There are no unique applications, indications, materials or specifications presented herein. This Premarket Notification, reported results from multi-phase in-vitro and in-vivo clinical trials and Feature Comparison Table demonstrate that Millennium™ is substantially equivalent to the Dental handpiece in terms of safety and efficacy.

# FEATURE COMPARISON TABLE

### CONCLUSION:

Millennium™ is substantially equivalent to several available, established dental technologies. Safety and efficacy have been demonstrated through in-vitro, invivo and clinical trials on animals and humans. Technically, Millennium™ performs through the same mechanical mechanism as other technologies but has the benefit of using a biocompatible agent as its cutting medium. Evidence of equivalence has been demonstrated through:

- . Clinical evaluation in randomized, double-blinded trials
- Pulp temperature studies .
- Scanning Electron and Optical Microscopy .
- . Equivalent performance specifications
- Promotional materials for equivalent systems .
- Equivalent intended uses •
- . Feature comparison table
