DENT1026: Principles of Occlusion in Denture Construction

Overbite is the vertical overlap of the upper anteriors over lowers; Overjet is the horizontal overlap of the upper teeth facial to the lower.

Centric relation is the positioning of the mandible as defined by the relationship of the mandible in the condyle within the glenoid fossa (a bone-to-bone relationship).

• a) True

• b) False

Vertical Dimension of Occlusion is the amount of separation of the maxilla and mandible when the mandible is hanging in physiologic rest; Vertical Dimension at Rest is the amount of vertical separation of the maxilla and mandible when the teeth are in centric occlusion (when teeth contact)

What is the normal measurement for "Freeway Space"?

• b) 2-4mm

• c) 4-6mm

• d) 6-8mm

Which occlusal rim defines the occlusal plane of a complete denture?

• a) mandibular occlusal rim

• b) maxillary occlusal rim

• c) both a & b

Protrusive excursion is the mandible moving front to back (anterior to posterior).

• a) True

• b) False

The Curve of Spee is formed by an imaginary line following the anteroposterior curve of the tips of the buccal cusps of the mandibular teeth, from the canine to the most posterior molar.

• a) True

• b) False

Group function is a feature where the posterior teeth out of occlusal contact when protrusive or lateral movements are performed; Canine guided occlusion is when there are multiple contact relations between the maxillary and mandibular teeth in later excursions.
