1900-1929

Generation

Name

Achievement

1901

Gysi

Release a gothic arch tracing method.

1901

Christensen

Release a Christensen phenomenon. Develop a check bite technique at the same time.

1907

Angle

Release the classification of Angle ( Angle's Key to occulusion ).

1907

Bennett

Release Bennett movement.

1908

Gysi

Develop Adaptable Articulator which is the first Articulator for Gysi. An incisal guide table can adjust it by installing an exclusive adapter.

1912

Zsigmondy

Measure a path of masticatory movement. Release the 3 phase theory of the mastication.

1914

Schroder,Rumpel

Develop a Schroder-Rumpel Articulator. A clutch is stuck to the joint part of the Adaptable articulator of Gysi, and it learns to fix a centric occlusion.

1914

Gysi

Develop the Articulator which be equipped the adjustment mechanism of the intercondylar distance.

1918

Monson

Develop a Monson Articulator.

1919

WadsWorth

Develop the Articulator of WadsWorth that the general idea of the lateral incisal guide table which split in two was adopted in the Articulator.

1920

Monson

Announce a Monson's spherical theory.

1920

Hall

Release a Hall's cone theory.
What is more, develop the Automatic anatomic Articulator in 1921, the Arbitrary Articulator in 1924, and a three-dimensional Articulator in 1926 .

1920

McCollm,Stallard

Propose Gnathology that a stomatognathic system is researched and treated as functional 1 unit.

1921

Hanau

Develop a Hanau-model H articulator.

1921

McCollm

Develop how to measure a Hinge axis.

1926

Hanau

Release synthetic mandibular movement theory to name as "HanauQuint".

1926

McCollm,Stallard

Establish California Gnathological Sociaty.

1929

Gysi

Release that a inclination of Sagittal condylar path is an average 33degrees when it does based on the Camper's line.

1929

Gysi

Release an Axis theory and a Facet theory. And, it is based, release a Full balanced occlucion.

1929

Yazaki

Propose mastication movement theory.
