Articulation errors

negative (want in fixed cases) and positive (want in complete dentures):
  1. positive error: occurs when articulator under compensates for the mandibular movement. These are unwanted “high spots” or “interferences” in posterior fixed restorations that must be eliminated. This error is preferred in complete dentures because it helps stabilize the prosthesis by providing tooth stock to adjust.

  2. negative error: occurs when the articulator over compensates for a mandibular movement. Therefore, the teeth disclude more freely when the mandible moves. This is accepted in fixed cases.

-normal intercondylar distance = 110mm
