Post insertion denture problems
Complaints about comfort of dentures causes Complaints about function of dentures and causes Complaints about the esthetics of the dentures and causes Complaints about the phonetics with the dentures and causes
3
Complaints about comfort of denture and causes
Sore spots Burning sensation Tongue and cheek biting Fiery redness of all tissues contacted by denture Redness of bearing tissues Pain in temporomandibular joint
4
Sore spots Sore spots in vestibule Sore spots posterior limit of upper
Over-extended border Sore spots posterior limit of upper Posterior palatal seal too deep Sharp posterior palatal seal Over-extension
5
Sore spots Single sore spots over ridge
Malocclusion in that area Inaccurate denture base Bubbles of acrylic resin Generalized soreness over the ridge Vertical dimension too great
6
Sore spots Soreness under lingual flange of lower
Centric occlusion not in harmony with centric, drives lower denture forward Over-extended lingual flange Soreness under labial flange of lower Too much overbite Patient’s habit, wants to masticate in protrusive Over-extended labial flange
7
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
8
Tongue and cheek biting
Posterior teeth edge to edge Over-closure Posterior teeth too far lingual or buccal
9
Fiery redness of all tissues contacted by denture including tongue and cheeks
Denture base allergy
10
Redness of bearing tissues
Ill-fitting denture Avitaminosis
11
Pain in temporomandibular joint
Vertical dimension of occlusal too small Centric occlusion not in harmony with centric relation Arthrits Trauma
12
Complaints about function of dentures and causes
Instability Interference General feeling dentures are not right, but with absence of pain (patient has high pain tolerance)
13
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
14
Instability When not occluding
Dehydration of tissues due to alcoholism Flabby tissues displaced when making impression
15
Instability When incising food Loss of posterior palatal seal
Anterior teeth placed too far labially Poor denture foundation (flabby anterior tissues) Improper incising habits
16
Instability When occluding in centric Mal-occlusion
Premature individual tooth contacts High occlusion on one side of arch High occlusion in bicuspid areas Upper denture riding on median hard palate
17
Instability When occluding in centric Flabby tissues over ridge
Teeth set too far buccally Centric occlusion not in harmony with centric relation
18
Interference Swallowing Upper Lower Over-extension in the posterior
Too thick in posterior Lower Over-extension in the lingual Too thick lingual posterior flanges
19
Interference Swallowing
Over-closure of the vertical relation of occlusion Posterior teeth too far lingual-crowds tongue Too great a vertical relation of occlusion
20
Interference Gagging Immediate gagging on insertion
Over-extension (upper) Too thick posterior border (upper) Disto-lingual flange too thick (lower)
21
Interference 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
22
Interference Clicking Vertical dimension of occlusion is too great
Unstable lower (borders over-extended)
23
Interference Deafness Vertical dimension of occlusion is too small
24
Interference Muscles of mastication become fatigued
Vertical dimension of occlusion is too small Vertical dimension of occlusion is too great
25
General feeling dentures are not right, but with absence of pain
Patient has high pain tolerance. Mal-occlusion Centric occlusion is not in harmony with centric relation Incorrect vertical relation of occlusion
26
Complaints about the esthetics of the dentures and causes
Fullness under nose Depressed philtrum and/or nasolabial sulcus Upper lip sunken in Shows too much of the teeth Artificial look
27
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
28
Esthetics Shows too much of the teeth Vertical dimension too great
Incisal plane too low Cuspids and laterals too prominent
29
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
30
Complaints about the phonetics with the dentures and causes
Whistle on “S” sounds Lips on “S” sounds “Th” and “T” sounds indistinct “T” sounds like “Th” “F” and “V” sounds indistinct
31
Phonetics Whistles on “S” sounds Lisp on “S” sounds
Too narrow an air space on the anterior part of the palate Lisp on “S” sounds Too broad and air space on the anterior part of the palate
32
Phonetics “Th” and “T” sounds indistinct “T” sounds like “Th”
Inadequate inter-occlusal distant “T” sounds like “Th” Upper anterior teeth too far lingual “F” and “V” sounds indistinct Improper position of upper anterior teeth either vertically or horizontally
