Intended Use

The LITETOUCH dental laser system is intended to aid during dental procedures performed in oral and maxillofacial surgery and dentistry. The Erbium: Y AG laser is indicated for a variety of hard tissue (tooth and bone) applications, and for the incision, excision, cutting, ablation, vaporization, and coagulation of soft tissue in oral and maxillofacial surgery and dentistry.

Device Story

LITETOUCH is a microprocessor-controlled Erbium:YAG laser system used by dental professionals in clinical settings. The system comprises a control panel, laser accessory with Erbium laser assembly, water spray equipment, high-voltage power supply, capacitor bank, cooling unit, and tip power detection module. It delivers laser energy at 2.94 microns to perform incision, excision, ablation, vaporization, and coagulation of oral hard and soft tissues. The clinician operates the device to perform procedures such as caries removal, bone resection, and periodontal debridement. The device provides precise tissue interaction, potentially reducing the need for traditional mechanical tools and improving clinical indices in periodontal treatment. Output is controlled via the console, with water spray used for cooling during laser application.

Clinical Evidence

No clinical data. The manufacturer relies on established scientific research and literature regarding the safety and efficacy of Er:YAG laser devices (2.94 micron wavelength, power up to 8.5 Watts) for hard and soft oral tissue, endodontology, and periodontology. The device parameters are within previously cleared values for similar predicate devices.

Technological Characteristics

Microprocessor-controlled Erbium:YAG laser system; 2.94 micron wavelength; power up to 8.5 Watts. Components: control panel, laser assembly, water spray, high-voltage power supply, cooling unit, tip power detection module. Complies with 21 CFR 1040.10/11 (Class IV laser), EN 60601-1, EN 60825-1, EN 60601-2-22, and CISPR 11/IEC 61000-4 EMC standards.

Indications for Use

Indicated for dental and oral/maxillofacial surgery patients requiring hard tissue procedures (caries removal, cavity prep, enamel etching/plasty), bone procedures (cutting, shaving, contouring, resection, apicoectomy, osteotomy, osseoplasty, crown lengthening), soft tissue/periodontal procedures (biopsies, gingivectomy, frenectomy, lesion removal, sulcular debridement, vestibuloplasty), and endodontal procedures (root canal access, pulpotomy, pulp extirpation, canal debridement/enlargement).

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.
