Rp: Final - Common Denture Complaints And Their Causes

Front 1

Instability of Maxillary Denture: Causes when not occluding...

Back 1

(1) overextension of borders and posterior limit
(2) Underextended borders
(3) Flabby tissues displaced during impression
(4) Dehydration
(5) Loss of posterior palatal seal.

Front 2

How is the posterior palatal seal lost?

Back 2

(1) Seal is placed on the hard palate
(2) not extended into the hamular notches
(3) insufficient compression of tissues

Front 3

Instability of Maxillary Denture: Causes when incising...

Back 3

(1) loss of posterior palatal seal
(2) anterior teeth placed too far labially
(3) Peer basal tissues (flabby)
(4) Improper habits during incising

Front 4

Instability of Maxillary Denture: Causes when occluding in centric...

Back 4

(1) Malocclusion (premature occlusion - individual, on one side of the arch, on bicuspid areas)
(2) Denture base riding on median hard palate
(3) Flabby ridge tissue
(4) Teeth set too far bucally
(5) Centric occlusion not in harmony with centric relation

Front 5

Instability of Mandibular Denture: when not occluding...

Back 5

(1) Overextension of borders
(2) Retruded tongue habits
(3) Flabby basal tissues
(4) Anterior teeth too far labially

Front 6

Instability of Mandibular Denture: causes when incising...

Back 6

(1) underextension into retromylohoid fossa
(2) poor incising habits
(3) flabby basal tissues

Front 7

Instability of Mandibular Denture:causes when occluding in centric...

Back 7

(1) Malocclusion (prematurities on individual teeth, on one side of the arch, extreme anterior or posterior prematurities)

Front 8

Cause of Sore Spots in the vestibule:

Back 8

- overextended borders

Front 9

Causes of Sore Spots in the posterior limit of the upper denture.

Back 9

- too much tissue compression
- palatal seal to sharp
- overextension

Front 10

Causes of Individual spots on ridge:

Back 10

- bubbles of acrylic inside denture
- malocclusion
- inaccurate dentrue base

Front 11

Causes of Generalized soreness of the ridge:

Back 11

- vertical dimesnion is too great
- inaccurate denture base

Front 12

Causes of sore spots in the Lingual flange of lower:

Back 12

- centric occlusion and centric relation do not harmonize (skidding)
- overextension
- plane of occlusion is too high (tongue must lift)

Front 13

Causes of sore spots in the labial flange of lower denture:

Back 13

- excessive vertical overlap
- habit: patient attempts to masticate in protrusive
- overextension

Front 14

Interference of Swallowing - Causes:

Back 14

- Upper: overextension posteriorly, too thick posteriorly
- lower: overextension, lingual posterior flanges too thick
- occlusal vertical dimension too small
- posterior teeth too far lingual crowding tongue
- oclusal vertical dimension to ogreat

Front 15

Gagging causes, immediately upon insertion....

Back 15

- overextension of upper
- posterior border of upper too thick
- distolingual flange of lower too thick.

Front 16

Gagging - delayed casues (2 weeks to 2 months later):

Back 16

(1) incomplete border seal
(2) malocclusion causing denture to loosen

Front 17

Clicking cause:

Back 17

- occlusal vertical dimension too great
- unstable lower

Front 18

Deafness cause:

Back 18

occlusal vertical dimension too small

Front 19

Fatigue of muscles of mastication cause:

Back 19

- occlusal vertical dimension too small
- occlusal vertical dimension too great

Front 20

General feeling dentures are not right but with absence of pain (patient has high pain threshold) cause:

Back 20

- malocclusion
- centric occlusion not in harmony with centric relation
- error in occlusal vertical dimension

Front 21

Burning Sensation Cause:

Back 21

- pressure on (1) anterior palatine foramen (2) posterior palatine foramen and (3) mental foramen

Front 22

Tongue or Cheek Biting cause:

Back 22

- posterior teeth edge to edge
- overclosure of vertical dimension of oclusion
- posterior teeth too far lingual or buccal

Front 23

Fiery redness of all denture bearing tissue cause:

Back 23

denture base allergy

Front 24

Redness of bearing tissues cause:

Back 24

- ill-fitting denture
- avitaminosis

Front 25

Pain in TMJ causes:

Back 25

- vertical dimension of occlusion too small
- centric occlusion and centric relation not in harmony
- arthritis
- trauma
