The GYSI "Adaptable" Articulator

Nothing to see Here!

Designed By:
Alfred E. Gysi

Manufactured By:
Dentist Supply Company of New York

US Patent:


This model of the Gysi "Adaptable" was produced for the American market in about 1912. It was the 3rd patented articulator with an incisal pin and guide assembly. Since Alfred Gysi introduced earlier models of the "Adaptable" in Europe prior to 1908 with this feature, he was likely the first to actually provide the incisal pin and guide as a part of an articulator. However, C.E. Luce was the first to patent this feature in 1911. 

The "Adaptable" also embodied important features that included adjustable rotation centers and adjustable condylar guides. It was the first articulator to include adjustable Bennett controls. Gysi used a recording device that is the "gothic arch" tracer to measure the incisal movements and a tracer with styli and "flags" to record the condylar paths. These measurements were used to set the controls of the "adaptable" articulator.
