Innovative technology
for high-quality dentures –
SAE spark erosion

Dental spark erosion has been used since 1982 for contact-free drilling, shaping and polishing. The system offers that high level of precision which is essential in dental technology and dentistry. Dental spark erosion is used for incorporating friction pins or for fitting attachment pins, swivel latches and all sorts of connecting attachments. In 1995, the spark erosion procedure was supplemented with a significant new area of application: the spark erosive passivation of implant-retained dental prostheses.

Above all, the demand for a cost effective high-quality dental prosthesis with dental connecting elements, specifically made of NPM alloys, led SAE company founder, Günter Rübeling, to use the industrial spark erosion procedure for dental technology and to obtain a patent for it.

Dental technicians can easily work with all dental alloys using the
SAE spark erosion procedure, in particular however, with the hard NPM CoCrMo alloys and titanium. In contrast to the the milling and drilling processes, the erosion process occurs without any contact. Electrical short circuit impulses cause fine erosion in the smallest µm range. This enables even complicated geometric shapes to be formed.

Since 1982, we have systematically developed tools and dental prosthetic elements for use with the SAE spark erosion procedure and for producing precision dentures in series.

Do you want to experience dental spark erosion on-site? You are most welcome. Come and visit us in Bremerhaven or Berlin and we will give you an in-depth demonstration with no obligation. Günter Rübeling looks forward to hearing from you.

How does the SAE spark erosion procedure work?
Spark erosion is a method of eroding different shapes and forms on electrically conductive metals by way of controlled electrical impulses between the tool electrode and the workpiece in dielectric fluid, a non-conductive fluid.

The erosion itself is, together with the so-called removal procedures (milling and drilling), an additional procedure for working with metals. There is, however, a significant difference. The rotation of the workpiece (drill mills) is dispensed with and the fixed electrode, being propelled vertically, enables the incredibly precise fit of a customized shape.

To obtain optimal results we recommend that you consistently keep to our own developed, systematic work processes and use exclusively the tested SAE materials.
