Laser welding of prostheses--an initial report.

Abstract Experience in laser welding fixed and precision removable partial prostheses has shown that, economically speaking, a considerable amount of time is saved when laser welding is used. The accuracy of the assembled restoration reflects the accuracy of the initial impression, since all welding is done on the master cast. Inaccuracies in assembly caused by transfers from the master cast along with investment and heat distortions are avoided. Anatomic form of the interproximal region is not obliterated. Maximum esthetics in the anterior section of the mouth is afforded, because individual sculpturing and veneering of abutments and replacements can be accomplished without the restrictions enforced by solder-joint design.
