Maxillary Impression Borders–Key Actions
Action #1: Ask the patient to create suction around a finger and the impression tray handle
Action #2: Ask the patient to create suction around a finger, pucker or pooch their lips and produce a maximal smile line
Action #3: Ask the patient to open their mouth wide and then move their mandible side to side to stretch the pterygomandibular raphe and allow the coronoid processes to shape the impression
Action #4: Pinch the patient’s nostrils closed and ask the patient to attempt to blow air through their nose. Make sure that the tongue is held down using a mouth mirror. Mark the hard-soft palate junction.
Action #4: Have the patient pronounce the word “aah” or cough to locate the vibrating line so it can be marked, thereby
identifying the area between the vibrating line and hard palate- soft palate junction
Mandibular Impression Borders–Key Actions
Action #1: Ask the patient to create suction around a finger and
the impression tray handle
Action #2: Pucker or pooch their lips and produce a maximal smile line
Action #3: Pronounce the word “Christmas” and the letters “Q” and “U” & pull the lower lip and cheek superiorly over the
impression tray
Action #4: Place a finger on the top of each side of the
impression tray and ask the patient to close the mandible against resistance using one second intervals of applied force
Action #5: Ask the patient to raise their tongue to the roof of
the mouth, then anterior to vermilion border, and then to the corners of their mouth. Ask patient to swallow (if possible)
Max record base
frontal: 22mm, posterior 8mm
mand record base
frontal = 18mm, posterior = 2/3 height of RMP
Canine lines helpful
for determining width of front 6
Determining VDO
- Physiological Rest Position
- Phonetics
- Closest Speaking Space
- Swallowing
- Tactile perception
- Patient-perceived comfort
VDR:
hum, lick lips, swallow, mmm-emma
Post insertion CD problems generally occur in one (or more) of four (4) general categories:
Fit / pressure-related problems Size / extension-related problems Occlusion related problems Random / other
24 hours post insertion, ——- should be considered first
occlusion
Soreness of the lining mucosa located at the periphery of the denture: cause –
overextension of peripheries
•Soreness located on the masticatory mucosa: cause –
traumatic occlusion
•Soreness located on the specialized mucosa: cause –
tongue biting
Insufficient room posteriorly
between tuberosity and retromolar pad
—>
Reduce acrylic thickness; use metal base if insufficient restorative space; consider surgery
Soreness on residual ridge or palate
Etio: Excessive vd
Solution:
Reduce posterior teeth via selective grinding, replace teeth in one arch at correct
VDO, or remake dentures
Thin mucosa over bony exostosis and tori
relieve denture, or refer to surgery
Difficulty swallowing can be caused by
Overextension of DL flange of mandibular denture
Overextension in posterior of maxillary denture
Excessive vertical dimension
Underextension- causes loss of
peripheral seal
■ Whistling:
etio
air in rugae area
■ Whistling:
solution
add wax in area to correct,
modify denture accordingly
• Lisping or slushy speech-
anterior teeth set too far forward, or insufficient IOD
The incisal angle varies depending on the magnitude of the
vertical and horizontal overlap, the arrangement of the occlusal plane and the condylar inclination. It is generally advisable to keep the incisal angle to a minimum in complete dentures.
If change is —– a new IOR is needed at CR position
greater than 2mmm
Excessive VDO
remove posterior teeth to make room for material
