An occluding surface built on temporary or permanent denture bases for the purpose of making maxillomandibular (jaw) relation records and for arranging teeth.
|
Occlusion Rims
|
|
Another name for occlusion rims.
|
Record rims
|
|
An occlusion rim is a horse-shoe shaped block of wax which is attached to a__________.
|
baseplate
|
|
Why is the facial surface of the occlusion rim contoured?
|
To restore an edentulous patient's appearance by simulating natural facial contours and to help the technician arrange teeth on it.
|
|
Why is the occlusal surface of the occlusion rim altered?
|
To indicate the proper occlusal plane.
|
|
The determination of the occlusal plane is usually done on the ________ occlusion rim.
|
MAXILLARY
|
|
A term used by old practitioners when recording the maxillomandibular relationship with occlusion rims
|
"take the bite"
|
|
Why should the length of the baseplate be slightly longer that is needs to be?
|
In order to adjust the occlusal plane to the proper level
|
|
The length of the maxillary occlusion rim should be __ millimeters from the greatest depth of the facial border to the surface of the occlusion rim.
|
22
|
|
The manibular occlusion rim should be __ millimeters high measured from the greatest depth of the mandibular facial border.

T OR F: The materials for constructing wax occlusion rims are: two baseplate wax sheets, maxillary and mandibular stabilized baseplates, a bunsen burner, knife, hot plate, and suitable spatula.
|
TRUE
|
|
What is used to make a smooth facial contour in constructing occlusion rims?
|
a hot spatula
|
|
An additional piece of wax is added to what surface of the occlusion rim and baseplate?
|
The facial junction of the rim and the baseplate.
|
|
The occlusal surface is reduced and smoothed using what?
|
a hot plate
|
|
Why is excess wax trimmed from the lingual surface of the rim?
|
To make the rim a uniform width
|
|
Why is it best to over contour a occlusion rim?
|
it enables the dentist to reduce the wax with a wax melting plate which is easier than adding wax to a occlusion rim to establish appropriate facial contours.
|
|
T OR F: Properly contoured occlusion rims are essential for proper denture techniques.
|
TRUE
|
|
T OR F: In order to restore proper facial contour, proper occlusal plane and maxillomandibular relationships the occlusion rim must be located properly on the baseplate.

TRUE
