The BBC designs are entirely manufactured of titanium and laser welded. Fixing screws and spacers are manufactured of titanium as well. BBC SP and BBC FA versions have an internal stainless steel spring.
BioBiteCorrector® SA and BioBiteCorrector® FA
The BioBiteCorrector SA (without internal spring) and the BioBiteCorrector FA (with internal spring) designs have a flat wire connector. This connector can be directly polymerized into resin or fixed on special tubes (see BioBiteCorrector Herbst appliance).
Thanks to the flat wire connector, the BioBiteCorrector SA and FA versions are placed centrally on the 1st premolar in the lower jaw and on the 1st molar in the upper jaw.
So these connectors do not have to be placed interproximally, like the screw connectors of the BBC SP and MS.
The BioBiteCorrector® FA supports the advancement of the lower jaw with an internal coil spring. The BBC SA works based on the functional principles of the Herbst-appliance and therefore does not have an internal coil spring.
