Comparison of the Arcon type and the Condylar type articulators on reproduction of lateral movements

Part I: Classification of the articulators in guiding systems

抄録

Adjustable articulators are divided into two classes based on the guiding systems of them, the Arcon type and the Condylar type. However, it seems particularly inappropriate to use these classifications when it comes to the reproduction of the lateral movement on the articulator. The object of this study is to classify the adjustable articulators according to the Arcon and the Condylar type guiding systems. We theoretically classified the adjustable articulators into eight groups according to their guiding systems. It has become clear that the articulators under discussion can be divided into three groups by using this method: Type II: articulator with Box type joint guiding mechanism, Type IV and VI: articulators with Slot type joint guiding mechanism.
