L4

Question Answer
1. hyper mobility of tooth/teeth
2. migration of tooth/teeeth
3. excessive wear - e.g. attrition
4. occlusal trauma - primary & secondary
5. fremitus - vibration sensation
unstable occlusion - 5 causes

L5

Question Answer
Mutually Protected Articulation (MPA)Occlusal scheme (gliding contacts)
-anterior teeth disengage the posterior teeth in all mandibular excursive movements
-posterior teeth prevent excessive contact of the anterior teeth in MIP
excessive forces on anterior teeth
-diastemas
-trauma/mobility
-facially proclined
Lack of Posterior Support can lead to...
Off axis loading and deflecting contacts
-fractured cusps and atypical tooth wear
Lack of Anterior Guidance can lead to...
20 teethWHO indicates that a
-functional
-esthetic
-natural dentition
has at least _________ teeth
Christensen's PhenomenonName of this finding?
-anterior guidance is designed to disengage posterior teeth
-incisal edge to edge contact occurs during protrusion and separates posterior teeth during protrusions
SHALLOWcasts on articular separate < seen clinical observations
-then condylar guidance settings are too shallow/steep?
STEEPcasts on articular separate > seen clinical observations
-then condylar guidance settings are too shallow/steep?

L6

Question Answer
anatomic/semi-anatomic teeth
-when dentures oppose natural dentition, semi-anatomic are preferable)
indications for what denture teeth?
-good residual ridges
-good neuromuscular control
-denture opposes natural dentition
non-anatomic teethindications for what denture teeth?
-poor residual ridges
-poor neuromuscular control
-arch discrepancies (class 2 or 3 or cross-bite)
-immediate dentures (except when opposing natural dentition)
-limited interarch space (<15mm)
lingualizedindications for what denture teeth
-high esthetic demands
-resorbed ridges
-malocclusion
Curve of Spee (A-P)compensating curve aka
Christensen's phenomenon
-the STEEPER the condylar inclination, the GREATER the posterior discrepancy of protrusion
Christensen's phenomenon
-the STEEPER the condylar inclination the GREATER the ___________
neurocentric occlusion
non-anatomic/monoplane teeth
-in ALL lateral excursions, you should observe at least 3 points of contact BILATERALLY
-R balancing ramp
-L balancing ramp
-anterior incisors
neurocentric occlusion
non-anatomic/monoplane teeth
-in ALL lateral excursions, you should observe at least _________ points of contact
lip bitingThese complications lead to what?
-reduced muscle tone
-increased horizontal overlap
cheek bitingThese complications lead to what?
-posterior teeth edge-edge
-inadequate VDO
tongue bitingThese complications lead to what?
-posterior teeth too far lingually
