and Answers (Most Recent Version,
Complete Study
If our restorations can survive margins being off, contours that are a little off, or shades that aren't quite
perfect... why do they almost never survive if the occlusion is wrong? - CORRECT ANSWERS
because of the force of the bite — biomechanics
____________ is the one element you cannot cheat — because physics is
never forgiving - CORRECT ANSWERS occlusion
Occlusion - CORRECT ANSWERS contact relationship between maxillary and mandibular teeth
Static occlusion - CORRECT ANSWERS contacts when the mandible is closed and stationary
(MIP, CR) — where teeth come together in the first place
CR (centric relation) is the most anterior and superior position of the condyles and its a __________
reference and __________ - CORRECT ANSWERS joint ; reproducible
MIP (maximum intercuspation) is where all opposing teeth have the most complete contact or "best fit"
with each other and its ____________ - CORRECT ANSWERS independent of condyle position
CO (centric occlusion) is a ____________ relationship, determined by the alignment and interaction of
the teeth themselves when the jaw is closed, providing a stable and functional position for __________
and __________ - CORRECT ANSWERS tooth-centric ; chewing and biting
One tooth should be restored in ________ (conformative treatment) - CORRECT ANSWERS
MIP
, Full mouth restoration should be restored in ________ - CORRECT ANSWERS CR
If you have no CR (no contact after restoration), the tooth will... - CORRECT ANSWERS super-
erupt
If your patient has periodontal disease, their maxillary teeth will... - CORRECT ANSWERS flare
out
Functional occlusion - CORRECT ANSWERS contacts when the mandible is in motion (chewing,
speaking, parafunction, protrusion)
What are 4 factors that explain why occlusion matters? - CORRECT ANSWERS • longevity of
restorations
• TMJ health
• mastication efficiency
• phonetics and esthetics
What parts of anatomy are important for occlusion? - CORRECT ANSWERS • TMJ (condyle,
disc, retrodiscal pad)
• ligaments: TMJ, sphenomandibular, stylomandibular
• muscles of mastication
Of all the anatomical structures involved in occlusion, what are the most powerful contributors? -
CORRECT ANSWERS muscles of mastication
What are the primary muscles of mastication? - CORRECT ANSWERS • temporalis
• masseter
