Laser welding today in prosthetic scene.

Abstract

In recent years, the laser welding has been established as a popular technique in the prosthetic clinical scene. For the successful use of the laser welding, it is important to know the character of the laser beam and the target metal. In this presentation, we will describe the 4 kinds of attractive use of the laser welding as following situations: 1. Repair for framework and/or clasp failures instead of soldering techniques. 2. Additional reforms for the frameworks in cases of increasing of the missing teeth, such as, the change from Kennedy classification 2 to classification 1. 3. Constructions for the dental appliance without corrosion damage. 4. Surface modification for increasing the hardness of irradiated surface.
