Dynamic Occlusion

Front 1

Contact of the maxillary teeth with the moving mandibular teeth

Back 1

Dynamic Occlusion

Front 2

Any movement of the mandible from MI resulting from to tooth to tooth contact is called?

3 examples of this are?

Back 2

Contacting Eccentric Movements

Protrusive

Retrusive

Laterotrusive

Front 3

The lower anterior teeth gliding along the lingual surfaces of the maxillary anterior teeth and disocclude the posterior teeth is called?

Back 3

Protrusion

Front 4

The influence of the contacting surfaces of the anterior teeth on mandibular movement is called?

During protrusion, what 2 things are mechanically coupled to disocclude posterior teeth?

The creation of space between the posterior teeth bilaterally during protrusion or on the mediotrusive side during lateral excursions is called?

Back 4

Anterior Guidance

Condylar Guidance and Anterior Guidance

Christensen's phenomenon

Front 5

__ is a form of eccentric movement

There are guided test movements employed by dentists to asses occlusal functions such as?

Back 5

Chewing

Protrusion

Working movements

Nonworking movements

What are 3 determinants of Mandibular Motion?

Back 12

Teeth

Musculature

TMJ

Front 13

Mandibular pathways directed away from the midline are termed?

Mandibular pathways directed toward the midline are termed?

Back 13

Laterotrusion/ Working side/ Functioning Side

Mediotrusion/ Nonworking Side/ Balancing Side

Front 14

Left lateral mandibular motion is the result of rotation of the __ around a vertical axis and translation of the __ downward, inward, and forward

Back 14

Left lateral mandibular motion is the result of rotation of the left working condyle around a vertical axis and translation of the right nonworking condyle downward, inward, and forward

Front 15

Right lateral mandibular motion is the result of rotation of the __ around a vertical axis and translation of the __ downward, inward, and forward

Back 15

Right lateral mandibular motion is the result of rotation of the right working condyle around a vertical axis and translation of the left nonworking condyle downward, inward, and forward

Front 16

The vertical displacement in the incisor point line from MI to e or d is the result of the teeth gliding over each other usually the?

Back 16

Canines

Front 17

Cuspid on the laterotrusive side guides the mandible and disoccludes the posterior teeth in laterotrusive movement (Christensen's phenomenon) is called?

This is coupled with?

Back 17

Canine Guidance

Lateral Condylar Guidance on the mediotrusive side

Front 18

Mutually Protected Occlusion:

In MI posterior teeth prevent excessive contact of anterior teeth.

-Chewing force is mostly here

In excursive movements, anterior teeth disengage posterior teeth protecting them from forces that are not directed along their long axes

Why is this important?

Back 18

Powerful muscles of mastication are near posterior teeth

Front 19

Multiple posterior tooth contacts on the working side during lateral jaw movement is called?

This is no as desirable as canine guidance

Back 19

Group Function

Right sided group function is shown

Front 20

Laterotrusive and Mediotrusie pathways:

If we trace the movement of the mandible in the horizontal plane at any point, __ pass between opposing cusps

__ are parallel in the direction of the non-working condyle

Back 20

Latertrousive (working) pathways

Mediotrusive (non-working) pathways
