Study Notes
- The Kilgore simulator should be positioned upright for maxillary and mandibular arch work.
- Frankfort Horizontal is the line between the infraorbital rim to the tragus of the ear.
- Camper's Plane runs form the ala of the nose to the tragus of the ear and is thought to correspond to the angulation of the maxillary occlusal plane.
Vertical Determinants of Occlusal Morphology
- Cusp height and Fossa Depth depend on several factors and conditions.
- Condylar guidance: Steeper guidance leads to taller posterior cusps.
- Anterior guidance: Greater vertical overlap leads to taller posterior cusps, while greater horizontal overlap leads to shorter posterior cusps.
- Plane of occlusion: More parallel to condylar guidance leads to shorter posterior cusps.
- Curve of Spee: A more acute curve results in shorter posterior cusps.
- Lateral translation movement: Greater movement, superior movement of the rotating condyle, and immediate side shift all result in shorter posterior cusps.
