Condyle
|
 The rounded articular surface at the end of the Mandible(Lower Jaw).It articulates with the Glenoid Fossa. |
|
Glenoid Fossa
|
 A deep concavity in the temporal bone at the root of the zygomatic arch that receives the condyle of the Mandible. |
|
Tubercle
|
 A slight elevation from the surface of the bone giving attachment to a muscle or ligament. |
|
Working Side
|
*Mandible Moving Toward the Cheek*
Condyle pivots within the socket and is better supported.
|
|
Balancing Side(nonworking side)
|
 *Mandible Moving Toward the Tongue* Condyle's a downward orbiting path,travelling a greater distance in space.It's more prone to injury or damage. |
|
Centric Relation(CR) - Chewing Cycle
|
A clinically determined position of the mandible placing condyles into their anterior uppermost position.It can be determined without pain in the TMJ.
|
|
Centric Stops
|
 Look at the Image |
|
Maximal Intercuspal Position
|
The complete intercuspation of the opposing teeth independent of condylar position*and sometimes do not depend on condylar position.
|
|
Laterotrusion
|
Condylar movement on the working side in the horizontal plane*working side.
|
|
Mediotrusion
|
A movement of the condyle medially*nonworking side.
|
|
Protrusive
|
Adj = protrusive; adv = protrusively, protrusiveness = noun. Means thrusting forward; adjective denoting protrusion.
|
|
Protrusion
|
A position of the mandible anterior to centric relation.
|
|
Centric Occlusion(CO)
|
The occlusion of opposing teeth when the mandible is in centric relation.
i.e. SUPERIOR/ANTERIOR AND OCCLUSION.
|
|
Eccentric Occlusion
|
Any tooth contacts other centric occlusion. (i.e. working, balancing, protrusion).
|
|
Horizontal Overlap
|
When the max. teeth overlap in horizontal direction.
