Which “space” is used to determine if the vertical dimension is correct? What numbers to you have the Pt count to check this?
speaking space…60-70…so “S” sounds
So you go to check CR at the esthetic try-in and ITS OFF…what do you do?
1.remove mand post’s 2.add wax until you get to your VDO 3.new bite reg/CR 4.remount mand 5.move teeth accordingly
_________: Purpose: To enhance retention & maintain the
peripheral seal of the maxillary denture base.
Posterior Palatal Seal
What 2 things does the Posterior Palatal Seal compensate for?
1.polymerization SHRINKAGE 2.Minor denture base movements during funciton
Clinically, what landmark do you establish to make your posterior palatal seal? What sound does the Pt make to find it?

1.5mm deepest and taper to 1mm
What are the 2 most important markings on the mand master cast when “refining” after the esthetic try in?
1.ridge line up 2.retromolar pad
What are the 2 most important markings on the mand master cast when “refining” after the esthetic try in?
1.midline 2.anterior land

Properly contoured dentures = Improved tolerance and _____
comfort
Properly contoured dentures = Facilitates _______ and control.
stability
Properly contoured dentures = Prevents chronic _____ of the lip or cheek.
biting
Stippling is usually more prominent ________ rather than directly over roots
between teeth
he interdental papilla must be ______ so as provide a more natural appearance and to avoid food impaction.
CONVEXY
The thickness of the labial ______ impacts lip contours. This is primarily developed during ________ the impression.
flange … border molding
_________:Purpose- Lip support and contour.
Additional contour raises the lip and the corner of the mouth.
Maxillary cuspid eminence
Mandibular cuspid eminence: Purpose: Lip support and ______
contour
What two factors help keep the buccal mucosa away from the biting zone?
1.slight concavity between gingival roll 2. periphery of the denture in posterior region
What part of the denture accommodates to the tongue placement?
lingual concavity
Which facial muscle prevents the denture from being displaced laterally?
buccinator
Lingual contour of the mandibular denture should be ______ and there should be a slight ________ to prevent tongue biting and to anchor the denture teeth within the acrylic resin.
CONCAVE….gingival roll
_________ of the buccal and lingual flanges can help hold the denture in place. These flanges define the boundaries of the “______ zone” where the force from the ______ equals the forces from the ______ and lips respectively.
Concavities…neutral…tongue…cheeks
Wax up…PALATE must be smooth and approx ___mm thick…why?? It will promote proper _______ articulation and reduce the incidence of ______.
3mm…speech…gagging
What type of joint is between the wax and teeth?
Butt joint between wax and teeth
WHICH APPOINTMENT do you get the patient’s approval????
After the esthetic try in!!!
When festooning (YAY new favorite word!!) is completed _____ the periphery of the denture flange to the inner edge of the land of the cast.
seal
When do we do a LAB remount?
AFTER processing
WHY do we do a LAB remount after processing the denture? (3)
- to get VDO back after processing 2.Get CR back 3.restore bilateral occlusion
LAB remount-make sure your pin is set back at ____.
zero!
Fixing occlusion errors after processing/LAB remount: Premature contacts, holding remaining teeth out of occlusion….
Deepen the FOSSAE..DO NOT shorten cusps
Fixing occlusion errors after processing/LAB remount: Cusp tips are TIP-TIP….
Move upper cusp inclines buccally. Move lower cusp inclines Lingually..(the cusps are narrowed)….DO NOT SHORTEN CUSPS
Fixing occlusion errors after processing/LAB remount: Upper teeth too Buccal in relation to the lower…
broaden the central fossae-Buccal cusps of lower are moved buccally…DO NOT SHORTEN CUSPS
What are the 3 places on the tooth that are OK to adjust in the LAB remount (post processing)? What do you AVOID?
OK—1.Cusp inclines 2.Central fosse 3.Marginal ridges…..AVOID 1.functional cusp tips-unless ABSOLUTELY required
What do you do after equilibrating in MIP?
Equilibrate in eccentric movements (working, balancing, protrusive)
Most occlusal discrepancies found during working and balancing can be corrected by reducing premature contacts on the ______ cusps of the maxillary teeth and the _______ cusps of the mandibular posterior teeth (non- centric holding cusps) otherwise known as the ____ rule
buccal of max…lingual of mand…BULL
Equilibration in working- Check the contacts on the buccal inclines of the upper buccal cusps. During working, they should all be about _____. If not, make the appropriate adjustments
equal
Slide the articulator through working again and observe the contacts on the balancing side, the lingual inclines of the lower buccal cusps. Premature balancing side contacts are reduced by grinding on the ______ inclines of the lower ______ cusps. If there are no balancing side contacts, the _______ side contacts should be reduced until balancing side contacts appear.
lingual inclines of lower buccal cusps….working
Equilibrate in protrusive. This may require grinding of the anterior teeth on the ______ of the maxillary and selective reduction of the ______ inclines of the posterior teeth.
lingual of the anterior…buccal
Put um in order…..Preparing Dentures for Delivery
Finishing/polishing dentures……Removing processed dentures from master casts….Fabrication of clinical remount casts…..Fabrication of face bow remount jig (index)…..Mount the maxillary remount cast on the articulator preserving the facebow transfer record
- Fabrication of face bow remount jig (index)
- Removing processed dentures from master casts
- Finishing/polishing dentures
- Fabrication of clinical remount casts
- Mount the maxillary remount cast on the articulator preserving the facebow transfer record
Prior to the insertion appointment the old dentures must be left out of the mouth for ______.
24 hours
What is the purpose of the facebow index (jig)?
The pupose of this jig is to preserve the face bow mounting record
Finishing…how thick should the palatal portion of the processed maxillary denture be?
3mm
Do not over polish the denture…it may _____ the acrylic
burn
How long do you have to soak the dentures in water before delivery?
72 hours (i wonder why?)
The remount casts will be used to mount the ______ remount records on the articulator.
CLINICAL
