Abstract:

A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue, the incising of the frenum, opurculum, anesthesia of the tooth, etching enamel for restorations or orthodontic appliance fixation, the welding of fixed prosthesis, removal of bacterial flora periodontal pockets, removal and/or vaporization of healthy or necrotic pulp, the vertical and/or horizontal condensation of gutta percha or any other root canal sealant, the cauterization of blood vessels in the oral cavity, vaporizing bone tissue, removing tartar, apical fusion of foramina, enlarging and shaping root canal, removing carbon from surface of teeth, removal of enamel, bleaching teeth, etching dentin, separating orthodontic brackets, merging hydroxyapatite to bone and enamel, amalgam removal and undercutting of carious and/or healthy dentin and/or cementum. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from one tenth to 50 watts.

Assignee:

American Dental Laser, Inc. - Troy MI

International Classification:

A61C 500
A61B 1736

US Classification:

433215

Abstract:

A dental laser assembly having a housing with a first and second laser cavity. The housing also includes an optical output port and a dental optical delivery system optically connected to the port. A first laser is contained within a first laser cavity which, when activated, generates a first laser beam while, similarly, a second laser is contained within a second laser cavity which, when activated, generates a second laser beam. Only one laser, however, is activated at a given time and the output beam from the activated laser is directed to the optical output port in the housing for use in dental applications. The first laser has optical qualities sufficient to perform a first set of dental procedures while the second laser has optical qualities sufficient to perform a second and different set of dental procedures.

International Classification:

A61C 500

US Classification:

433215

Abstract:

A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from zero to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.
