- Abstract
Purpose: Interchangeability between articulators allows mounted casts to be transferred accurately from one articulator to another. The purpose of this study was to evaluate the interchangeability of 109 new, unused interchangeable articulators in the centric position. Materials and Methods: The interchangeability of 38 unused Whip Mix model #2240 and 71 unused model #3040 semiadjustable articulators was evaluated using the Whip Mix #2245 check system as the standard. Vertical discrepancies between the check system cylinders were also measured. Results: Within the standard for interchangeability established by the Whip Mix #2245 check system (< 94 µm horizontal discrepancy), 101 (93%) of 109 articulators were interchangeable (34 were model #2240 and 67 were model #3040). Overall, the amount of vertical space between the check system cylinders was ≤ 52 µm in 99.4% of the model #2240 articulators and 99.7% of the #3040 articulators. Conclusion: New, unused Whip Mix model #2240 and #3040 articulators are potentially interchangeable in the centric position.
