Importance of trial denture visits
allowing patient to view tooth arrangement and make
changes if needed
Patient complains something is wrong with my dentures. I don’t know what it is. The most likely reason could be
- Occlusion
- Esthetics
- Retention
- Occlusion
During insertion appointment
- Insert U/L w/o occluding
- 1st CR verification
- initially adjust both dentures separately
- initially adjust both dentures separately
CR recording in trial denture is by ?
- I/O wax record (Dead soft wax similar to Aluwax) ,
Injectable bite registration material
Not an alterable factor • H overlap of Ant teeth • V overlap of Ant teeth • CR • Cusp height of Post teeth • Curve of plane
CR
others are alterable
(?) All the things to be accomplished before a clinical remount, except:
- lab remount,
- mounting max cast with facebow preservation
- mounting mand cast with CR
mounting mand cast with CR
To accomodate teeth in record base, the preferred sequence would be-
1) grind the lower record base
2) create a window in record base
3) grind the tooth
Heel interference is seen in lab during lab remount . Treatment?
- reduce mand distal area, not maxillary as perforation in maxillary denture can cause loss of suction & cohesion
CO ≠ CR at intermaxillary records at trial denture appointment. What will you do next?
a. remount max and mand cast at new CR
b. remount mand with new CR
c. check VDO and occlusion
d. Check for movement of record base, remount mand cast with new CR
d.Check for movement of record base, remount mand cast with new CR
(Remount and Re-set teeth at try-in)
NOTE: If monoplane- occl adjustments may be
done intraorally and then new CR record
for remount
Patient was wearing Interim dentures for 3 weeks. The U/L dentures become loose. How will you treat?
- soft chairside reline both dentures, with the more unstable denture first against the relatively stable denture. Recall in 1 month.
A patient fractured a new denture with exceptional occlusion, VDO and esthetics. Treatment?
- repair first and then rebase (definitive)
Reline and rebase impressions are done in function, after occlusion is checked.T/F
T
Surgical stent is used for ? (interim fabrication)
1.used to recontour soft and hard tissues during extraction visit. (Use guide to check for
blanching)
2.represents the intaglio surface
Not a contraindication for immediate dentures
- Uncontrolled hypertensive patient
- controlled diabetes
- blood coagulation disorders, difficult wound healing
- radiation in the head and neck area
controlled diabetes
4 years old denture which is loose but has good VDO & occlusion. Treatment
- reline with pressure cure (hard?) acrylic
~1-3yrs lifespan
True about tissue conditioners if left for too long
1.will cause mechanical injury to
tissue
2. Will cause infection due to colonization (2 correct answers)
Tooth selection . Best choice for a 45 years old female patient with upper natural dentition-
- IPN 30 degrees
Severely resorbed mand ridge for an overlay denture. Upper complete denture in a bruxer. Teeth selection
- IPN U-12 degrees, L-0 degrees
What will you modify to enhance balance in a Class III CU/CL denture in lateral excursions?
- Curve of wilson
- Curve of spee,
- Height of cusps,
- all of the above
Curve of wilson
Advantage of staging extractions in Interim/Immediate dentures is -
- allow healing time between appointments
2. better predictability in terms of VDO (2 correct answers)
Patient complains of muscle fatigue after a recent rebase. Most probable cause -
Increased VDO
Generalized redness on the ridge. Least probable cause
- Poor denture base fit,
- Increased VDO,
- Denture acrylic allergy,
- Patient did not remove denture
-Denture acrylic allergy
