Analysis of the lateral condylar adjustment of nonarcon semiadjustable articulators.

An analysis of the lateral condylar inclination adjustment of the slot-track semiadjustable articulator was performed by using a fully adjustable articulator as a simulated patient. Pantographic tracings were made and transferred to the semiadjustable articulator. The lateral condylar inclination of the articulator was then rotated to allow it to follow the pantographic tracings as closely as possible. The results indicate that the Hanau formula or an arbitrary setting of 15 to 20 degrees does not provide the most accurate articulator setting possible.
