Gold-free noble metal alloys have been used for over three decades in the human body as implants (knee and hip joints). We have been successfully using these alloys at the Rübeling laboratory since 1980.

The spark erosion technique was first utilised in the 1980s at the Rübeling dental laboratory for the fabrication of dentures. This technique made it possible to achieve precision fitting dental restorations of all types in all suitable metals and to replace expensive gold alloys with biocompatible, gold-free metals.

The spark erosion technique developed in the Rübeling laboratory has been recognised by dental science and is used under licence by over 700 dental laboratories both at home and abroad.

The gold-free noble metal alloys can be used for all types of dentures for all applications, even for high-end telescopic and implant-based restorations.

The key benefits of the spark erosion technique for the patient are the superb fit of the dentures and the reduced manufacturing costs, which give the Rübeling dental laboratory an enormous price advantage even over cheap dentures from abroad.
