METAL PLATE REPAIR WITH LASER WELDING
Why is laser welding spotlighted now ?
It has been said that pure titanium prosthesis has not been treated with soldering or welding using flame
or electric resistance, and chromium-cobalt alloy has been classified into to be treated very hard.
But laser welding enables us to weld these two parent metals together easily without deteriorating physical property.
In addition, heating spot is minimized. and welding is done on working stone models without impairing cast,
resin plate and artificial teeth, promising an accurate fit.

Summary
Laser welding enables us to weld the minimum required spot of prosthesis functioning in the mouth.
Compared to a conventional method (soldering), modification and repair can be done with laser welding
much more easily and firmly, welding together to an ideal form.
Until now, it has been considered that a metal plate was not so easily repairable,
but now laser welding makes us possible to modify the design and repair with minimum labor and time
in accordance with occlusal change in the mouth.
