[Angle between occlusal plane and horizontal plane of articulators with quick mounting face bow]

Correct determination of the occlusal plane is important for estetic, phonetic and masticatory function of the denture. As many different criterias are used in clinical practice to determine the occlusal plane on the wax rims, the aim of this study was to find the angle between the occlusal plane and the horizontal plane in the articulators with the quick mounting face bow. The measurements were made on the casts of 30 eugnath individuals with at least 28 natural teeth, mounted in S.A.M. articulator through the transfer with the Quick mounting face bow, in the position of maximum intercuspation. Measurements were made with a precise caliper and were transferred to the calibrated paper. The angles were measured between the occlusal plane and the horizontal plane. The angle is 9.42 degrees +/- 4.1 degrees in the population of this country. This result can be helpful to determine the occlusal plane or to control if the occlusal plane, determined by the other methods is in the correct position in articulator.
