Question 1

• It attempts to define the _____________________ between all of the anatomic components; condylar position coincides with ___________________.
• The mandible moves on a ___________, as seen in a hinge axis opening. This movement, in the __________, happens when the mandible in centric relation makes a purely rotational opening and closing border movement around the transverse horizontal axis, which extends through both condyles.
• Mandibular movement occurs around a ___________ during a lateral excursion. This movement occurs in the _____________ when the mandible moves into a lateral excursion. The center for this rotation is a vertical axis extending through the rotating or working-side condyle.
• The mandible also rotates at one side drops down during a lateral excursion. When the mandible moves to one side, the condyle on the side opposite the direction of movement travels forward. As it does, it encounters the eminence of the glenoid fossa and moves downward simultaneously. When viewed in the frontal plane, this produces a downward arc on the side opposite the direction of movement, rotating around an anteroposterior (_________) axis passing through the other condyle.
• When the mandible slides forward so that the maxillary and mandibular anterior teeth are in an end-to-end relationship, it is in a ______________. Ideally, the anterior segment of the mandible will travel a path guided by contacts between the anterior teeth, with complete disocclusion of the posterior teeth.
• The bodily shift of the mandible in the direction of the working side was first described by Bennett. The angle formed in the horizontal plane between the pathway of the nonworking condyle, the mandibular lateral translation, and the sagittal plane is called the ____________
