What distinguishes an arcon articulator from a non-arcon articulator?

An arcon articulator is distinguished by having the condylar elements positioned in the lower compartment of the articulator, mimicking the natural anatomy of the craniomandibular system more accurately than a non-arcon design. This arrangement provides a more realistic representation of the relationship between the maxilla and mandible during movement, which is essential for achieving proper occlusion and function in dental prosthetics.

In comparison, a non-arcon articulator typically has the condylar elements in the upper compartment or may not adhere to the same anatomical relationships found in arcon designs. This difference can affect the accuracy of measurements and the functionality of dental work, making the arcon design more favorable for precise restorative procedures.

While the facebow, incisal pin, and the fixed upper member features are also important aspects of articulators, they do not define the fundamental anatomical distinction between arcon and non-arcon types in the way that the position of the condylar element does.
