Occlusion (Lecture 1: Mutually Protected Occlusion) Exam 1 Study Guid
1. The is a functional unit of the body: masticatory system
2. What is the masticatory system responsible for?: chewing, speaking, swal- lowing
3. What is the masticatory system made up of?: - bones
- joints
- ligaments
- teeth
- muscles
4. Mutually protected occlusion is an occlusal scheme where: teeth pro-
tect teeth & teeth protect teeth: posterior teeth protect anterior teeth
anterior teeth protect posterior teeth
5. How do posterior teeth protect anterior teeth?: posterior teeth prevent exces- sive contact of the
anterior teeth in maximum intercuspation
6. What is maximum intercuspation (position)?: the complete intercuspation of the opposing teeth
(when the fossa of one tooth interlocks with the cusp tip of the opposing tooth)
7. The cusp to fossa relationship allows for " " of the masticatory sur- faces, out of the 4
antagonizing cusps involved 2 are "functional" and 2 are "non-functional": interlocking
8. What does the "interlocking" of the masticatory surfaces result in?: consis- tent and stable
occlusion as it guides the teeth to the end point position at the end of the chewing cycle
9. The surface of maxillary anterior teeth and the edge of the

mandibular anterior teeth are the occluding surfaces in maximum intercus- pation: lingual
surface of MAXILLARY
incisal edge of MANDIBULAR
10.Which surfaces of the maxillary teeth and mandibular teeth are the occlud- ing surfaces in
maximum intercuspation?: lingual surface of maxillary, incisal edge of mandibular
11.What does the end point of the chewing cycle (envelope of function) result in?: tooth-to-tooth
contacts
- ideally w/ the cusp/incisal edge contacting a flattened surface of the opposing tooth, which acts as a
final "landing pad"
12.What is the end point of the chewing cycle called?: envelop of function
13.What does the repetitive tooth contacts in mastication result in?: gradual wear of enamel
leading to tight interdigitation of the teeth
14.What three components can lead to destabilization of a patient's occlu- sion?: - tooth loss
