Occlusion (Lecture 4: Occlusion Related to Prosthodontics) Exam 2
1. the vertical and horizontal overlap of the canine teeth disclude the posterior teeth
bilaterally in the excursive movements of the mandible: canine guidance
2. multiple contact relations between the maxillary and mandibular teeth in lateral
movements on the working-side whereby simultaneous contact of several teeth acts
as a group to distribute occlusal forces: group guidance
3. working side: side to which mandible moves
4. While group function is theoretically not as ideal as canine guidance, it does not
necessarily mean that group function will lead to : pathology
- Group function can be an acceptable occlusal scheme provided that it does not
result in any signs and symptoms of occlusal trauma
5. contacts that occur on the opposite side that the mandible is moving towards:
balancing interferences
6. Balancing interferences are contacts that occur on the side that the
mandible is moving towards: opposite
7. Typically, the is a well coordinated system with muscles firing in a
synchronous manner to control precise mandibular movements: masticatory system
8. What does the masticatory system control?: precise mandibular movements
9. Why aren't balancing interferences generally not well tolerated by the body?:

the unexpected contact causes ERRATIC muscle activity on the CON-
TRALATERAL side
10.Balancing interferences are generally not well tolerated by the body be- cause
the unexpected contact causes muscle activity on the
side.: erratic muscle activity on the contralateral side
11.What can the erratic muscle contractions cause?: muscle and joint pain
- the neuromuscular system will try to adjust its muscle activity to avoid
interference but it is not always successful in doing so.
12.T/F: The neuromuscular system will try to adjust its muscle activity to avoid
interference, and is always successful in doing so.: False! It is NOT always successful
in doing so
13.The may be the source of discomfort if the occlusal load exceeds
adaptive capacity of the periodontium: tooth
14. are rarely seen in patients with stable occlusion: balancing
interferences
15.What can introduce balancing interferences?: changes in occlusion due to tooth
loss or tooth wear
16. in due to tooth loss or tooth wear can introduce balancing
interferences: changes in occlusion

, Occlusion (Lecture 4: Occlusion Related to Prosthodontics) Exam 2
17.Solution to balancing interferences: perform occlusal adjustment to remove
discreptancies
18.The focus on avoiding balancing interferences becomes magnified when a
significant portion of the tooth's original morphology is : changed
19.What is a crown?: cap that covers a tooth
20.How is tooth structure removed for a crown?: removed circumferentially and
occlusally around a tooth
- the shape of the tooth is recreated in a restorative material that is
subsequently cemented onto the tooth
- restores the form and function of the tooth
21.Tooth structure is removed and around a tooth and the shape of the
tooth is recreated in a restorative material that is subsequently cemented onto the
tooth. This restores the form and function of the tooth: circumferen- tially &
occlusally
22.When does a tooth need a crown?: "She Eats Corn"
- tooth STRUCTURE
- improve ESTHETICS
- change CONTOURS
