study Flashcards
the complete denture patient who whistles while trying to make S sounds should have the whistling corrected by
recontouring the anterior palate of the denture
The main advantage that resin artificial teeth have over porcelain artificial teeth is that?
Resin teeth can chemically bond to the base
Main objective of tooth supported overdenture therapy is to?
Decrease the rate of bone resorption
Patient has been wearing dentures for 20 years wants new dentures. Exam reveals
tissues is irritated. Current dentures are defective. What is the first important step?
trim denture and add tissue conditioner
***When treating a patient with an edentulous maxillary and mandibular with teeth most significant concern is?
occlusal plane
When is a kinematic facebow recommended for clinical use
dont use for dentures. use TERMINAL HINGE AXIS
When waxing complete denture bases to their final form before processing what
objective should not be accomplished or desired?
creating the correct incisal and canine guidance
A 2 stage surgical practical is required for immediate complete dentures. The most important reason for removing the posterior teeth first is that
this procedure improves the accuracy of final/secondary impressions after healing
****at a follow up visit, patient complains her mandibular complete dentures seem loose. what is the LEAST likely reason for dislodgement?
??????????
denture teeth are set in neutral zone (you want them there)
When tuberosities are found to be too large for fabrication, surgical reduction should be
limited to:
a osteoplasty
(or would this be called an alveoloplasty ????)
most likely cause of spherical porosity in the denture is?
monomer boiling
The compete denture that was processed in the pre clinical course was process using the long cure polymerization method at
165F/9 hours
theory of the max central incisor resembling the face form is called:
(based on the shape of the face)
geometric
based on age, sex, and personality
dentogenics- frush and fisher
to maximize the complete denture stability, mandibular molars should?
be place over the crest of the ridge
The most significant disadvantage when fabricating immediate complete dentures is
no anterior try in
so disadvantage would be the lack of esthetic anterior trial before processing
well contoured set of dentures used muscles contractions to stabilize the dentures. best example is
buccinator
**mainly palatoglossus muscle and superior constrictor affect distal phalange of mand denture
inflammatory hyperplasia is a condition assc with that
wearing a denture
what is
anterior regions are affected more than the posterior region
lesion episulus fissarta
(mobile tissue)
what is the protrusive record for in the complete denture fabrication?
it is for BALANCED occlusion (6mm)
to adjust articular condyle
zarbs textbook states that 24 hour follow up is advised?
patients have better perception of denture
the compensation curve in complete dentures refers to
curve of monson
anatomical landmarks to help establish the posterior border?
hamular notches, fovea palatini
common causes of frequent dislodgements of the maxillary complete denture include?
under extension, occlusal deficiencies
a denture wearer has angular cheillitis, etiology is?
candida and vitamin deficiency (also associated with OVD issues)
the patient who is in an edentulous mandible opposing max arch of natural teeth is best treated by??
denta implants or overdenture
With wax trial dentures in the mouth, patient closes in CR. There is discrepancy, what should you do?
remount mandibular cast with new interocclusal record
surgical stent(template) for immediate denture patient is?
required for alveoloplasty or bone smoothing
which type of occlusion is NOT indicated for complete dentures
canine guidance
name of the dental device to parallel campers plane
fox
(campers is ala to tragus)
(frank fort from under eye to ear)
all the following presentations are seen in balanced CD occlusion except
except contact of teeth in all mandibular movements
posterior teeth do not have cusps
teeth arranged on flat occlusal plane
monoplane occlusion
cuspless mandibular posterior teeth arranged on a flat plane
only max lingual cusps in occlusion with central fossae areas of mand posterior teeth
lingualized nonbalanced
bilateral simultaneous occlusal contacts of the anterior and posterior teeth in excursive movements
balanced occlusion
what is the purpose of PIP
evaluate and improve adaptation of denture to the tissues
*******patient who present with combination syndrome may benefit with
implants to the mand anterior area (overdenture)
most important factor to the success of a CD
patient/doctor relationship
**zarbs recommends the following for ANTERIOR denture teeth
none of the above
what to avoid when rebasing a CD
changing the OVD
***lab reline should be prescribed when the CD has
looseness
in what significant way does the process for IMMEDIATE CD differ from the conventional CD
NO anterior try in
what is true about the posterior palatal seal
placed immediately posterior to the vibrating line
minimizes function of max buccal cusp
lingual cusps of max should be the ones functioning, mand are typically cupsless in this occlusal scheme
lingualized occlusion
what is the purpose of the clear surgical stent
to reduce enough alveolar bone
what is NOT an advantage of digital dentures
what are:
esthetics
are: cost, easy to produce, time
how many visits do you need for digital dentures
4-5 visits
when do you need a lab remount
when the lab didnt close the flask enough and need to fix occlusion
