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!
