Abstract
Abstract This invention relates to a method for intraoral microwelding of dental appliances without destruction of oral tissues. The process is practiced by employing a high power laser with power limited to 12 joules per pulse for 8 milliseconds at a wavelength of 1.06 microns. The method contemplates employing a lens with such laser as would yield a spot weld of 0.010 to 0.030 inch diameter.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
93 words
A method for intraoral microwelding of intra-oral appliances comprising the steps of: (a) locating an appliance at an intraoral area where the appliance is to be welded; (b) irradiating a spot on the appliance to weld the spot with high power radiation provided by a laser with energy between approximately 4 and 8 joules per laser pulse and for a duration of approximately 6 milliseconds; and (c) focusing said radiation on the spot to an area between approximately 0.010 and 0.015 inches whereby a weld is formed without causing damage to a tooth.
Claim 2
Independent Claim
93 words
A method for intraoral microwelding of intra-oral appliances comprising the steps of: (a) locating an appliance at an intraoral area where the appliance is to be welded; (b) irradiating a spot on the appliance to weld the spot with high power radiation provided by a laser with energy between approximately 4 and 8 joules per laser pulse and for a duration of approximately 6 milliseconds; and (c) focusing said radiation on the spot to an area between approximately 0.010 and 0.015 inches whereby a weld is formed without causing damage to a tooth.
Claim 3
Dependent Claim
25 words
A method in accordance with claim 1 wherein the focusing of step (c) is accomplished by disposing a lens between the laser and the appliance.
Claim 4
Dependent Claim
19 words
A method in accordance with claim 1 wherein step (b) includes using a neodymium laser as the energy source.
