Yesterday there was soldering...
The
future of joint technology in dental laboratories belongs to laser
welding. Joint
technology through welding means secure joints with high strength and bio-
compatibility thanks to the use of weld fillers of the same type. The need
to employ laser-welding units in dental laboratories is based on the clear
recommendations of the German Health Department. Quote:
"Soldering must only be carried out when
unavoidable. " Quote:
"The number of alloys in the mouth of a
patient is to be kept to a minimum. " The soldering technique cannot meet these demands.

With soldering you can only achieve approximately 40% of the original strength whereas with laser welding we can achieve 100% or greater strength of the original casting! |
