title: Evaluation of variables associated with the transverse horizontal axis.
abstract: The effect of transverse horizontal axis deviations on the vertical and horizontal orientation of maxillary and mandibular members was investigated on a laboratory articulator model. Twelve axis deviations (+30, +25, +20, +15, +10, +5, -5, -10, -15, -20, -25, and -30 mm groups) within a 55 mm dimension model were evaluated. Three trials at each transverse horizontal axis deviation demonstrated significant changes in maxillomandibular orientation after mounting the mandibular member with a standardized intermember mounting record. A linear regression analysis produced an equation for predictive interpolation of anterior-posterior shift as a result of axis deviations from +30 to -30 mm.
