Verifying the reliability of interchanging casts with semiadjustable articulators.
Interchangeability of a semiadjustable articulator could be of significant convenience and economic benefit to the restorative dentist. The manufacturer of the Whip-Mix Model 2240 articulator claims such interchangeability. This study evaluated the accuracy of the cross-mounting capability of eight such articulators, then compared the measured results with those obtained from eight semiadjustable instruments for which the manufacturer makes no such promise of interchangeability. It was determined that the Model 2240 articular did possess accuracy when a measuring device was transferred between the eight materials tested.
