Most patients experience some problems adjusting to new dentures. Common complaints include sore spots from poor fit, burning sensations from pressure on nerves, and instability when not chewing. Bite issues can also cause difficulties with eating, talking, and jaw pain. Regular checkups are important to identify and address issues through relines or new dentures. Proper fit is key to comfort and function.

2. Post insertion denture
problems

3. Objective:
-To know the problems and complaints that
may face the completely edentulous patient
after insertion of new denture
- To identify the causes of the problems and
complaints

4.  Most patient have problems of some type while
adjustng to new denture.
 Maintenance after denture insertion is a key to
denture success.
 Therefore, the patient must have scheduled
appointments for his recall visits.

5. Post insertion denture problems
 Complaints about comfort
 Complaints about function
 Complaints about the esthetics
 Complaints about the phonetics

6. Complaints about comfort
 Sore spots
 Burning sensation
 Tongue and cheek biting
 Fiery redness of all tissues contacted by denture
 Redness of bearing tissues
 Pain in temporomandibular joint

7. Sore spots
 Sore spots in vestibule:
 Over-extended border
 Sore spots under posterior limit of upper denture:
 Posterior palatal seal too deep
 Sharp posterior palatal seal
 Over-extension

8. Sore spots
 Single sore spots over ridge:
 Malocclusion in that area
 Inaccurate denture base
 Bubbles of acrylic resin

9. Sore spots
 Generalized soreness over the ridge:
 Vertical dimension too great
 Inaccurate denture base

10. Sore spots
 Soreness under lingual flange of lower denture:
 Centric occlusion not in harmony with
centric, drives lower denture forward
 Over-extended lingual flange

11. Sore spots
 Soreness under labial flange of lower denture:
 Too much overbite
 Patient’s habit, wants to masticate in protrusive
 Over-extended labial flange
HTTP://www.rxdentistry.net

12. Burning sensation
 Anterior hard palate and anterior alveolar ridge
areas
 Pressure on anterior palatine foramen
 Bicuspid area to molar tuberosity
 Pressure on posterior palatine foramen
 Lower anterior ridge
 Pressure on mental foramen

14. Tongue and cheek biting
 Posterior teeth edge to edge
 Over-closure
 Posterior teeth too far lingual or buccal

16. Fiery redness of all tissues contacted by
denture including tongue and cheeks
 Denture base allergy

17. Redness of bearing tissues
 Ill-fitting denture
 Avitaminosis

18. Pain in temporomandibular joint
 Vertical dimension of occlusal too low
 Centric occlusion not in harmony with centric
relation
 Arthrits
 Trauma

20. Complaints about function
 Instability
 Swallowing
 Gagging
 Clicking
 Deafness
 Muscle fatigue
 Eating

21. Instability
 When not occluding
 Over-extension of border and posterior limit
 Under-extended border
 Loss of posterior palatal seal
 Posterior palatal seal on hard palate
 Posterior limit not in hamular notches
 Insufficient posterior palatal seal

22. Instability
 When not occluding
 Dehydration of tissues due to alcoholism
 Flabby tissues displaced when making impression

23. Instability
 When incising food
 Loss of posterior palatal seal
 Anterior teeth placed too far labially
 Poor denture foundation (flabby anterior tissues)
 Improper incising habits

24. Instability
 When occluding in centric
 Mal-occlusion
 Premature individual tooth contacts
 High occlusion on one side of arch
 Upper denture riding on median hard palate

25. Instability
 When occluding in centric
 Flabby tissues over ridge
 Teeth set too far buccally
 Centric occlusion not in harmony with centric relation

26.  Difficulty in swallowing:
 Upper denture:
 Over-extension in the posterior
 Too thick in posterior extension
 Lower denture:
 Over-extension in the lingual
 Too thick lingual posterior flanges
Swallowing

27.  Swallowing
 Over-closure of the vertical relation of occlusion
 Posterior teeth too far lingual-crowds tongue
 Too great vertical dimension of occlusion
Swallowing

28.  Gagging
 Immediate gagging on insertion
 Over-extension (upper)
 Too thick posterior border (upper)
 Disto-lingual flange too thick (lower)
 Psychological factors
Gagging

29.  Gagging
 Delayed gagging (2weeks to 2 months after insertion)
 Incomplete border seal allowing saliva under denture
 Mal-occlusion causing denture to loosen, allowing saliva under
denture
Gagging

30.  Clicking
 Vertical dimension of occlusion is too great
 Unstable lower (borders over-extended)
Clicking

31.  Deafness
 Excessive reduction of Vertical dimension of occlusion
Deafness

32.  Muscles of mastication become fatigued
 Vertical dimension of occlusion is too small
 Vertical dimension of occlusion is too great
Muscles of mastication become fatigued

33. a. Inability to Eat Anything:
Due to:
1-1st time denture wearer ( need time).
2-Cuspal interference.
Eating:

34. b.Inability to Eat Meat:
Due to:
1-Flat cusped posterior teeth.
2-Low VOD with low muscle efficiency.
3-Unbalanced articulation as no teeth contact on balanced
side to shear the fibrous food.

35. Improper peripheral seal
Food under the denture

36. Complaints about the esthetics
 Fullness under nose
 Depressed philtrum and/or nasolabial sulcus
 Upper lip sunken in
 Shows too much of the teeth
 Artificial look

37. Esthetic
 Fullness under nose
 Labial flange of upper too long or too thick
 Depressed philtrum and/or nasolabial sulcus
 Labial flange too short, too thin
 Upper lip sunken in
 Upper anterior teeth too far lingual

38. Esthetics
 Shows too much of the teeth
 Vertical dimension too great
 Incisal plane too low
 Cuspids and laterals too prominent

39. Esthetics
 Artificial look
 Technique set-up, the teeth are in too regular alignment
(individualize by rotating and shortening some teeth)
 All teeth same shade
 Lack of grinding incisal edges and angles
 Lack of individualizing gingival contours and color of denture
base

40. Complaints about the phonetics
 Whistle on “S” sounds
 Lisp on “S” sounds
 “D” and “T” sounds indistinct
 “F” and “V” sounds indistinct
