|
Term
| Two types of jaw movement |
|
Definition
|
|
Term
|
Definition
| With the jaw in the retruded position, the condyle can rotate around the terminal hinge axis. This opens the jaw around 20mm |
|
|
Term
|
Definition
| The forward and downwards movement of the condyle to allow wider opening of the jaw |
|
|
Term
|
Definition
1. The condyle is pulled forward by the lateral pterygoid muscle
2. The condyle slides down the articular eminence |
|
|
Term
|
Definition
The point about which the condyle rotates around during the rotary phase
(Only with mandible in retruded position) |
|
|
Term
|
Definition
| The side to which the jaw moves during mastication |
|
|
Term
|
Definition
| Opposite side to the working side- should have no occlusal contact |
|
|
Term
| Retruded contact position |
|
Definition
| The mandibular position occuring at the very first contact between upper/lower teeth with the condyle is the most superior position |
|
|
Term
|
Definition
| Effect of the shape of the articular eminence on the protrusive movements of the mandible |
|
|
Term
| Result of condylar guidance |
|
Definition
| The lowering of the angle of the mandible as this condyle slides down the articular eminence |
|
|
Term
|
Definition
| When the jaw is moved laterally, all teeth are excluded except the canines on the working side, which slide over each other |
|
|
Term
|
Definition
| the separation of teeth due to a prominent tooth to tooth contact (may be natural such as canine guidance) |
|
|
Term
|
Definition
| During lateral movements, two or more teeth remain in contact |
|
|
Term
|
Definition
| Tooth contacts not involved in the normal functioning of the jaws (i.e. mastication/chewing)- typically habitual such as chewing pencils, nail biting and bruxism |
|

Term

Term
|
Definition
| A mechanical device which recreates the patients jaw. Study models can be positioned to study max/man relationship. Used by technicians for crowns, bridges and dentures |
