False; errors may exist
Subsequent steps convert dentures to acrylic resin which ____ the possibility of further corrections
Limits
____ is a preliminary arrangement of denture teeth that has been prepared for placement into the patient’s mouth to evaluate esthetics and maxillomandibular relationships
Trial denture
____ is the process of placing the trial denture into the patient’s mouth for evaluation
Trial placement
What are the 8 things that need to be evaluated for the trial denture?
OVD, Centric occlusion; midline, vertical and horizontal overlap, occlusal plane, buccal corridor, phonetics, and esthetics
____ is the distance measured between 2 points when the occluding members are in contact
OVD
How much space is normal between teeth when in PRP?
2-4 mm
When saying “s” and “ch” sounds should there be contact of max and mand teeth?
No
____ verifies that the casts are mounted correctly on the articulator
Centric occlusion
In ____ mounting, teeth interdigitate perfectly (no space around cusps); condylar ball should contact fossae wall
Accurate mounting
If the CR/CO is off, which cast should be remounted?
Mandibular
Should there be gums showing when smiling?
No

The incisal plane of teeth should parallel _____
Interpupillary line
The posterior teeth should be _____ centered over denture-bearing area
Mediolaterally
