Abstract


Since its initial development, the laser has been hailed as a potentially useful welding tool for a variety of applications. The scope for technical and commercial laser welding applications has increased greatly since the development of multi-kilowatt CO2 lasers around 1970. The laser’s capability of generating a power density greater than 106 watts/cm2 is a primary factor in establishing its potential for welding. Numerous experiments have shown that the high-quality precision weld joints are permitted by lasers which are rivaled only by electron beam. By reviewing recent work in the field, this article will present the state of the art of laser welding. This paper attempts to give an insight into the laser welding and its principle and types of lasers used for orthodontic purposes, types of dental alloys used by the orthodontist, and effect of various laser parameters. The literature review has made this apparent that laser assisted orthodontic welding will continue to grow and will become an unparalleled technology for orthodontic arena. The laser thus offers an easily maneuvered, chemically clean, high-intensity, atmospheric welding process producing deep-penetration welds (aspect ratio greater than 1:1) with narrow Heat Affected Zone (HAZ) and subsequent low distortion.
