Indications for Use

The OpuDuo Dental Laser System is intended to aid during dental procedures performed either in hard or soft oral tissue. The Er: YAG laser component is indicated for caries removal, cavity preparation, and enamel etching. The CO2 laser component is indicated for vaporization, incision, excision and coagulation of oral soft tissue in procedures such as gingivectomy; frenum release; removal of soft tissue, cysts and tumors.

Device Story

Dual-wavelength dental laser system (Er:YAG 2.94 microns; CO2 10.6 microns) for hard and soft oral tissue procedures. Er:YAG delivers pulses up to 1J/pulse and 12W; CO2 delivers continuous wave up to 10W or pulses up to 6W. Operated by dental professionals in clinical settings. System features PC-based control (PCM-5820) with touch-screen interface, replacing embedded CPU and soft keys of predecessor. Includes online power monitoring for Er:YAG, dual-mast delivery system, and microswitch-based handpiece identification for safety. External cooling system manages internal thermal loads. Output used by clinicians to perform precise tissue ablation, coagulation, and excision. Benefits include improved ergonomics, enhanced safety via handpiece correlation, and real-time power monitoring.

Clinical Evidence

Bench testing only. No clinical data provided. Verification and validation activities were performed based on risk analysis to confirm the safety and performance of the modified design features.

Technological Characteristics

Dual-laser system (Er:YAG 2.94 microns, CO2 10.6 microns). PC-controlled (PCM-5820) with touch-screen interface. Features: online power monitoring, dual-mast delivery, microswitch handpiece safety interlocks, external cooling system. Software runs on Windows NT. Smaller form factor and reduced weight compared to predicate.

Indications for Use

Indicated for dental patients requiring hard tissue procedures (caries removal, cavity preparation, enamel etching) or soft tissue procedures (vaporization, incision, excision, coagulation, gingivectomy, frenum release, removal of cysts/tumors).

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

The CO2 laser component is indicated for vaporization, excision and coagulation of oral soft tissue in procedures such as gingivectomy; frenum release; removal of soft tissue, cysts and tumors.

## Device Description:

The Opus Spectrum c is a model of the Opus 20 Dental Laser System which is intended to aid during dental procedure performed either in hard or soft oral tissue. This is a dual laser system incorporating an Er: Y AG laser and a CO2 laser. The system is operating at a wavelength of 2.94 microns and 10.6 microns respectively. The Er:YAG laser delivers to the tissue pulses with energies up to 1 joule per pulse and power up to 12 Watts. . The CO2 laser delivers to the tissue power in continuous mode (CW) up to 10 Watts and pulses (SP) up to 6 Watts.

## Substantial Equivalence:

The Opus Spectrum dental laser system is substantially equivalent to the Opus 20 dental laser system (OpusDent Ltd.). In fact, it is an improved model of Opus 20 that is similar to its predicate device except the following features:

- · Opus Spectrum software runs on Window NT® Operating System while Opus 20 incorporates a stand-alone software.
- · Opus Spectrum is controlled by a PC Computer (PCM-5820) while Opus 20 is controlled by an embedded CPU.
- · Opus Spectrum has a Touch-Screen technology instead of soft keys.
- · Opus Spectrum incorportes an On Line Monitor that monitors the Er:YAG lasing power in addition to the two power meters in Opus 20.
- · Opus Spectrum has two masts one for Er:YAG and one for CO2. Opus 20 has one mast for both lasers.
- · Additional safety feature was added to Opus Spectrum. A microswitch is located in each handpiece carrier to indicate the handpiece in use and to identify miscorrelation between handpiece and desired laser mode.
- · Opus Spectrum has external cooling system that cools the coolant of the internal cooling systems while Opus 20 has internal water/air cooling system.
- · Opus Spectrum incorporates a new power supply.
- · Opus Spectrum is smaller in size and it is half weight than Opus 20.
- · The external design of the Opus Spectrum differs from Opus 20.
