Removable Complete Dentures Flashcards
An edentulous stock tray should be selected that is ___ mm larger than the outside surface of the residual ridge
4-5 mm
Histologically oral tissue are allowed for keratinization to increase if complete dentures are not worn for
6-8 hours
The distal end of maxillary, complete denture posteriorly at the midline should usually end ___ to the fovea palatine
1-2mm anterior
As presented in lecture, the study of masticatory performance of a debt age group at an average of 90% demonstration less performance by denture wearers at an average rate of only:
60%
In the lecture definition per training to a complete denture, the “resistance to horizontal or rotational forces” is:
Stability
When the soft palate is almost concident with the vibrating line this would indicate a ____ palate
Class III
True or false. A class II residual ridge morphology has a radiographic height of 11 to 15mm measured at the least vertical height of the mandible.
FALSE
Deglutition occurs about ____ times a day.
500-600
Maximal bite force appear _____ less for complete denture wearers, then of persons with all natural teeth
6x
5-6x
Mandibular residual ridge resorption is ___ the amount of maxillary residual ridge resorption
4x
Actual chewing time per meal is:
450 sec
Definition of border molding:
Shaping of the border areas of an impression material by _____ or _____ of the soft tissue adjacent to the bordered to the duplicate contour and size of the vestibule
Functional or manual manipulation
With lose of natural dentition and/or function with removable prosthesis, masticatory efficiency is likely reduced. This masticatory efficiency can be as low as _____ % is adequate for compete digestion of foods
25%
During the remodelling process post extraction healing, the annual rate of reduction in the height of the mandible is:
0.1-0.2mm
The distobuccal border of the buccal vestibule is primarily influenced by the _____ muscle
Masseter
______ is the resistance to displacement of the denture base away from the ridge
Retention
The posterior palatial seal preparation should extend laterally beyond the hamular notch by
3mm
When establishing maxillary and mandibular wax rims at the appropriate vertical measurement at the canines should be_____ .
40mm
The distal portion of the occlusal table bilaterally is bounded by what anatomic structure?
Pterygomandibular raphe
The ______ process of the _______ often may limit the width of the maxillary complete denture borders in the area lateral and distal to the tuberosities.
Coronoid, mandible
At which temperature should the water bath be set to properly “temper” the green stick impression compound?
140 degrees Fahrenheit
The total time teeth are subjected to functional forces of mastication and deglutition during a day amounts to approximately:
15-20 mins
Based on the definitions presented in the lecture, resistance to vertical movement of a denture base toward the residual ridge is:
Support
The _______ notch is produced by contraction of the muscles limiting the lost lateral extent of the Mandibular buccal vestibule.
Masseteric
The retromolar pad contains the terminal part of the tendon of the _______ muscle
Temporalis
The anterior-posterior palatial seal is dependent on the soft palate form. This type of soft palate form allows the broadest seal.
Type A
The vibrating line is always on the _______
Soft palate
Comparing measurement of vertical dimension of rest (VDR) to vertical dimension of occlusion (VDO)
VDR > VDO
TRUE OR FLASE. There is no difference in chewing efficiency between cusped and cuspless denture teeth
FALSE
The average interocclusal clearance is:
0.2-0.5mm
Posterior portion of the maxillary and Mandibular bite blocks be the width of
8-10mm
