Look at slide 24
…
In a lateral working diagram, what does the arrow represent that is facing facially
Right working (lateralrusive) (Slide 25)
What does NON_FUNCTIONAL imply?
mandibular movement is not possible
Which movement is not possible in the mandible
when the arrow is pointing Distal lingually
Border in the sagittal plane, what does MI stand for?
Maximum intercuspation
Border in the sagittal plane, what does F-T-E stand for?
Edge to Edge incisal
Border in the sagittal plane, what does MP stand for?
Maximum protrusion point
In the Horizontal plane, what Does MP stand for, and where is it located?
Maximum protrusion, most anterior
mandibular lateral translation is the FIRST PART of the LATERAL MOVEMENTOF THE MANDIBLE, depicted when the MEDIAL POLE of the _____ _____ starts to TRAVEL DOWN the SLOPE and the ________ ______ and against the MEDIAL WALL OF THE FOSSa
Non-working condyle, Articular eminence (30)
The MOVEMENT of the mandibular lateral translation is exhibited as a MEASURMENT OF THE DISTANCE BETWEEN THE _______ ____ of the NON-WORKING CONDYLE and the ______ _____ of the GLENOID FOSSA
MEDIAL POLE, medial wall (30)
if condylar guidance was the only vertical determinant of occlusion, the cusp angles would bee to be MORE or LESS then the angle of the articular eminence
LESS
What is ANTERIOR guidance a function of?
the relationship between the maxillary and mandibular ANTERIOR teeth
Anterior guidance Consists of?
Vertical and horizontal overlaps as measured at the anterior teeth
if condylar guidance was the only vertical determinant of occlusion, the cusp angles would bee to be MORE or LESS then the angle of the articular eminence
LESS
What is ANTERIOR guidance a function of?
the relationship between the maxillary and mandibular ANTERIOR teeth
what are the units of ACF and PCF (and what does it mean?)
anterior controlling factors
4 units forword
4 units downword
as the amount of vertical overlap _______, the ANTERIOR guidance angle __________
Increases, increses
horizontal overlap remains ________
unchanged
If ACF and PCF are both at 45 degrees, where do the mandibular first premolars lay?
Also at 45 degrees (moves away from horzontal reference plain)
As the plan of occlusion becomes more nearly _______ to the angle of the articular eminence, the posterior cusps will need to the ________ in order to avoid collision with eachother
Parallel, Shorter
during ________ movements, cusps pass between ridges and over grooves. A a result, the horizontal determinants also influence the ________ of cusps
Eccentric, placement
Horizontal determinants infuence the ________ and ________ of the ridges and grooves on the occlusal surfaces
DIRECTION, LOCATION
during ________ movements, cusps pass between ridges and over grooves. A a result, the horizontal determinants also influence the ________ of cusps
Eccentric,
What occurs to the cusps as the horizontal reference plane becomes LESS PARALLEL to the condylar guidance angle?
The steeper the cusps can be
The closer the tooth is the the midline…
The smaller the angle between the laterotrusive and mediotrusive pathways
the more ________ the movement of the working condyle, the _______ is the angle formed by the medotrusive and laterotrusive pathways
posterolateral, larger
Plane of occlusion, condition and Effect
Condition: more parallel the plane to condylar guidance
Effect: shorter the posterior cusps must be
