Device Story

Millennium is a hydrokinetic tissue cutting system for dental procedures. It uses an Er,Cr:YSGG solid-state laser to energize atomized water droplets. These high-speed water particles perform mechanical, non-thermal incision, excision, and ablation of hard and soft intraoral tissues. The device consists of a console and a flexible fiberoptic handpiece. A visible light beam at the handpiece tip assists the clinician in targeting the treatment area. The clinician adjusts optical power and water spray flow. Used in dental clinics, the device provides a non-contact alternative to traditional rotating burs or air-abrasion systems. By using a biocompatible water medium for mechanical separation, it aims to provide quick, clean tissue removal while minimizing thermal damage.

Clinical Evidence

Evidence includes multi-phase in-vitro and in-vivo clinical trials on animals and humans. Studies included randomized, double-blinded clinical evaluations, pulp temperature studies, and scanning electron/optical microscopy to assess tissue removal quality and safety. Results demonstrated equivalent performance to traditional dental handpieces.

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. Handpiece: flexible fiberoptic with visible aiming beam. Adjustable spray flow and optical power.

Indications for Use

Indicated for Class I-V cavity preparation, caries removal, and hard tissue surface roughening or etching in dental patients. Clinicians should exercise caution for patients with local anesthetic allergies, heart disease, lung disease, bleeding disorders, sleep apnea, or immune system deficiencies.

Regulatory Classification

## DEVICE DESCRIPTION:

The Millennium™ hydrokinetic tissuc cutting system is a diverse instrument for Pine Millennium - Hydrokins. Millennium™ utilizes advanced laser and performing coverer. comologies to incise, excise and ablate intraoral soft and hard water alonitation totatively. An erbium, chromium, yttrium, scandium, gallium gamet (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.

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

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

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 that 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.

#### 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.

## CONCLUSION:

Millennium™ is substantially equivalent to several available, established dental technologies. Safety and efficacy have been demonstrated through in-vitro, in-vivo 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 .
