• Device Name: DIODENT MICRO DENTAL LASER SYSTEM, MODELS 810 AND 980
• Applicant: Hoya Conbio, Inc.
• Product Code: GEX · General, Plastic Surgery
• Decision Date: Mar 16, 2007
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 878.4810
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

The DioDent Micro 810/980 Dental Laser System is intended for incision excision, ablation, vaporization, and/or coagulation of oral soft tissue (including marginal and interdental gingival and epithelial lining of free gingiva). It is also intended for light activation for bleaching materials for teeth whitening, and laser assisted bleaching/whitening for teeth whitening.

Device Story

DioDent Micro 810/980 is a solid-state Gallium Aluminum Arsenide (GaAlAs) semiconductor diode laser. It emits invisible laser energy at 810nm or 980nm wavelengths. The system includes an autoclavable flexible treatment fiber and handpiece. Operated by a clinician in a dental setting, the device is activated via a footswitch. A color touch-screen display allows adjustment of laser output levels. The laser operates in continuous wave or pulse modes to perform soft tissue surgery (incision, excision, ablation, vaporization, coagulation) or to activate bleaching materials for teeth whitening. By providing precise tissue interaction, the device facilitates various oral surgical procedures and cosmetic whitening, potentially reducing patient discomfort and recovery time compared to traditional methods.

Clinical Evidence

No clinical data provided. Bench testing only.

Technological Characteristics

Solid-state Gallium Aluminum Arsenide (GaAlAs) semiconductor diode laser. Wavelengths: 810nm or 980nm. Delivery system: autoclavable flexible treatment fiber and handpiece. Operation: continuous wave or pulse mode. User interface: color touch-screen display. Energy source: electrical, footswitch-controlled.

Indications for Use

Indicated for incision, excision, ablation, vaporization, and hemostasis of oral soft tissue in patients requiring dental procedures such as biopsies, frenectomy, gingivectomy, implant recovery, pulpotomy, and sulcular debridement. Also indicated for light-activated teeth whitening.

Regulatory Classification

Identification

The laser source of the DioDent Micro 810/980 is a solid-state Gallium Aluminum Arsenide (GaAlAs) semiconductor diode. It produces invisible laser energy at the 810-nanometer or 980nm wavelength. The delivery system consists of an autoclavable flexible treatment fiber threaded through a lightweight, autoclavable hand piece. Activation occurs when the operator enables the laser and presses the footswitch. Releasing the footswitch suspends laser treatment. The footswitch can function as an on/off switch. A color touch-screen display panel allows the operator to adjust or set laser output level with minimal effort.

Dear Ms. Burns:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls.
