RESUMEN

The application of laser welding technology allows titanium to be welded predictably and precisely to achieve accurate fit of a milled framework. Laser energy results in localized heat production, thereby reducing thermal expansion. Unlike soldering, laser energy can be directed to a small area, making it possible to laser weld close to acrylic resin or ceramic. This article describes the use of laser welding to repair an implant titanium milled fixed denture. A quick, cost-effective, accurate repair was accomplished, and the repaired framework possessed adequate strength and the same precise fit as the original framework. (J.

SUMMARY

A titanium milled implant fixed partial denture was repaired with the help of laser welding and inserted, allowing for quick, cost-effective repair. The repaired framework appeared to possess adequate strength and the same precise fit as the original framework. The joining of highly reactive titanium is made possible with laser welding; this cannot be accomplished with soldering.
