1: Complete Dentures Flashcards
Dentures are not a substitute for natural teeth, they are a substitute for what
no teeth
What is the ultimate objective of complete dentures
to go from an edentulous arch to temporary base pates to the final denture
Complete denture fabrication is difficult because you must satisfy many variables, what are some (10)
adequate retention pleasing smile right mold and shade of teeth proper articulation pleasing lip support midline symmetrical. no swallowing problems. able to eat soft foods. able to enunciate words clearly. acceptance by the whole world!
What are the first three steps of complete denture fabrication
- making the preliminary impressions and casts.
- custom tray fabrication with wax spacer.
- acceptable border molding techniques.
After proper border molding, what are the next four steps
- making the final impressions
- beading and boxing the final impressions
for the master casts. - locating and scribing the posterior palatal seal.
- making temporary baseplates
and occlusal wax rims.
After adjusting the maxillary baseplate and wax rim (8) what are the next 5 steps
- achieving acceptable facial fullness.
- Marking the midline.
- Establishing the fox plane.
- Taking the face-bow transfer.
- Adjusting the mandibular baseplate and wax rim.
Once you establish the vertical dimensions (14) what are the next three steps that involve the patient
- Verifying unrestricted swallowing.
- Verifying proper phonetics and esthetics.
- Recording centric relation
After patient records are taken (15-17) what are the next four steps
- Standardizing a semi-adjustable articulator.
- Mounting casts, baseplates/wax rims.
- Setting maxillary-mandibular anterior teeth.
- Setting maxillary-mandibular posterior teeth.
After you have set the maxillary and mandibular teeth, what are the next five steps
- Anterior-posterior wax try-in of teeth.
- Inserting/delivering the denture.
- Counseling on limitations of the complete dentures.
- 24 and 72 hour post-operative appointments.
- Post-operative appointments as need.
Everything we do as a “dentist” is temporary except what
extractions
We perform procedures with the idea that the results will be durable and long-lasting, but none of them are what? Our treatment planning processes should reflect this reality!
permanent
The balance of our success rests with what four things
Patient compliance and regular checkups. (Good home oral hygiene.)
Anticipated material degradation.
Everyone’s realization of any limitations.
Patient acceptance.
What is YMATO
Who do you need to impress?
you, me, all the others
This is the psychological phenomenon by which humans pay more attention to and give more weight to negative rather than positive experiences or other kinds of information; jealousy, and insecurity hinder progress
negativity bias
How often does insurance pay for a new denture
5-10 years
True or False
Treatment of some patients may well be beyond the clinical and psychological scope of the dental practitioner
True
This "denture bird" carries dentures in pocket or purse. carries Swenson’s Complete Dentures and whip. brings own tools. wants to drive the denture bus. attacks ferociously at try-in. wants to set own teeth. never pays and dentist delivers dentures
My-way magpie
This "denture bird" Brings gifts and flattery as a decoy. Loves to demean previous dentists. Preys on young enthusiastic dentists. Constantly looking for new prey. Regularly demands ridiculous desires. Can’t seem to make a positive decision and stick to it.
Karate Hawk
This denture bird has two separate lower dentures; one set for speaking, one set for eating.
Tawkorchoo gobbler
This denture bird;
Bruxers never remove their dentures,
they grind and complain.
Overloaded and abused denture-bearing tissues.
Refuses to believe that the dentures are not the problem.
Bruxing Booby
This denture bird;
Also known as I Usta Duck “I usta look like…”
twentyish attire.
Strangely, can find no old picture.
Wants to return to the days of yesteryear.
Provides herself with “plumpers”
Minewise mallard
Never underestimate this in a patient
gag reflex; expect every patient to gag
This feature is very important to the patient when taking impressions
breathing
What three things should you anticipate when taking an impression
gagging
drooling
tray moving
What are four tricks to help with drooling and gagging when taking impressions
Have the patient lean forward at waist, stick their tongue out to minimize gagging.
Have patient raise napkin to catch any drooling.
Hold the tray firmly in place the entire time.
Topical anesthetic spray/gel.
What is something that if strained and not lifted out of the way of impression material will not allow for adequate seating
lips
It is almost always predicted that the impression will not capture which area
the depth of the vestibule and all necessary surrounding architecture
What is the #1 most missed maxillary area
pre-maxilla area (with labial frenum)
What is the #1 most missed mandibular area
lingual flange area; sub-lingual “S”
This type of impression tray is used for preliminary alginate dentulous impressions; The tray is deeper for capturing teeth and ridge, no adhesive to be used
and the design of the tray retains impression material.
dentulous rim-lock tray
This type of impression tray is for preliminary alginate edentulous impressions, tray is flat for edentulous ridge, no adhesive is used, and the design of the tray retains the impression material
edentulous rim-lock tray
This type of impression tray is good for a multitude of impressions (preliminary or final), can be altered to fit mouth, is perforated, but adhesive recommended and can be disposed of after use.
stock plastic tray
This impression can be made in stock tray
preliminary impressions; not meant to be accurate final impressions
The impression tray can be made more adaptive by adding what
periphery wax around the tray; can extend the borders of the edentulous tray
What dictates the success of an edentulous impression
capture the depth and total extent of the vestibule
How do you properly border mold the periphery wax to the intraoral contours
massaging the lips and cheeks
This is something you can do to prevent gagging during maxillary impressions
raise legs to tense stomach muscles
This is an irreversible hydrocolloid impression material which the power-liquid ratio must be followed at all times
alginate
What are three characteristic of a completed preliminary impression
should have no major pressure spots or voids
should capture all peripheral extensions
should capture all anatomic landmarks
This is something you should NOT do to the cast of the preliminary impression
trim! protect and preserve all edentulous impressions
How long should you process the custom tray for
3 minutes
What are the five purposes of the wax spacer
room for impression material stops tray from overseating do not remove until after border molding remove without destroying border molding remove the wax spacer then add adhesive before final impression
Adjust the custom tray and wax spacer to what depth
2mm short of the vestibule and at the frenum attachments
Why are you adjusting the custom tray and wax space
to assure there is sufficient room for border molding and impression material
What are four properties of custom tray handles
no dinosaur handles!
cannot go straight out; will hit lips
cannot go straight up/down; will hit opposing arch
should go up/down and out of the mouth
What are four properties of a finished custom tray
no sharp edges
no interfering undercuts
2mm short of the vestibule
the handle is not hitting the opposing arch
