Look to see how the patient's maxilla is positioned. Is it pointing upward? Is it facing downward? Is it tilted to the right or the left? When the patient is sitting erect, pull the cheek aside and look at the maxilla from the side and also from the front. That should duplicate the position of the maxillary cast on the articulator.

There are some rare occasions when you place the facebow apparatus on the articulator and the maxillary model interferes with the closure of the articulator.

You should realize there is a limited area within the articulator that the model can be placed. If your model doesn't fit in that space then you either have to build a larger articulator or move the model. So have your instructor move the model to the next best position.
