Purpose of recall appointments is to eliminate

problems faced by patient in wearing of

denture.

Dentist must LISTEN, EXAMINE, TREAT the

condition.

Symptoms :

Fall on speaking, laughing

Food entrapment

Pain

Why do denture become loose?

1. Decreased retentive forces

2. Increased displacing forces

3. Support problem

8/15/2017 13smile

1. Why Decreased retentive forces?

Lack of seal

Air beneath impression surface

Xerostomia

Poor neuromuscular control

What causes lack of seal?

Under extended borders in depth & width

Mx : addition of tracing compound to required

extension & processing it with acrylic

8/15/2017 14smile

8/15/2017 15smile

• Incorrect PPS

Mx : border molding done in PPS & processed with

new material

8/15/2017 16smile

Extend of

posterior border

should not extend

beyond the PPS ;

as posterior

over extension

can lead to looseness of

denture while eating , laughing , coughing

etc…

8/15/2017 17smile

Addition of tracing compound to under extended borders8/15/2017 18smile

In elasticity of cheek

(agening,scleroderma,fibrosis)

Mx : slight reduction of depth &

width of borders &

border molding done

as increments.

RRR

Mx : relining

What are the causes for air entrapment

beneath impression surface?

8/15/2017 19smile

Poor fit during technical works

- Deficient impression

- Damaged cast

- Warped denture

- Over adjustment of impression surface

Mx : areas to be identified using Pressure

Indicating Paste (PIP) & relined

8/15/2017 20smile

8/15/2017 21smile

Over trimming for insertion

Mx : rotational path of insertion, soft liner

used

8/15/2017 22smile

8/15/2017 23smile

Excessive relief

Mx : relining

Trapped air expands as denture move away

from supporting tissue until it reaches

borders & seal is broken.

Change of fluid content of supporting tissue

due to:

- Lack of recovery of tissue from pressure of

old denture

- Use of diuretics

Mx : ensure old denture in not worn 72hrs prior

to impression making, reline/rebase by

minimum pressure technique8/15/2017 24smile

What are the causes for xerostomia?

Diabetes

Drugs (atropine,

phenothiazine,CPZ)

Menopause

Irradiation

Vitamin deficiency (A,

B12, B2, folic acid)

Sialolithiasis

Xerostomia causes reduced ability to form seal along

borders & impression surface of denture

Mx : artificial salivary substitutes, soups, intermittent

sipping of water, pilocarpine hydrochloride, sucking

sour candy8/15/2017 25smile

How can poor neuromuscular control interfere

with denture wearing?

Incorrect denture shape

Mx : denture should occupy in neutral zone &

polished surface should be contoured

8/15/2017 26smile

Tongue unable to control denture

Mx : proper tongue positioning need to be

trained

- Practice mouth opening / closing with tongue

in forward position resting against inside of

denture flange & lower front teeth even

while receiving any food.

- If maxillary denture become loose, advice

the patient to close the mouth & swallow

8/15/2017 27smile

Change in shape relative to old denture

Mx : duplication of old denture with provided

VD & occlusion

Upper/lower motor neuron disorder

Mx : denture adhesive

8/15/2017 28smile

2. Why increased displacing forces?

Over extended borders(posterior & distal

corner of maxillary denture)

Mx : use PIP & correct the borders

Poor fit

Mx : reline/rebase

Denture not in optimal space

Mx : reshaping the borders

8/15/2017 29smile

Occlusal problems

- Anterior & posterior prematrities

Mx : selective grinding

- MIP not coinciding with CR ( unable to

control mandible movements, poor ridge,

skeletal class II , non anatomic teeth )

Mx : remounting

- Incorrect plane of occlusion ( last tooth too

far, tuberosity)

Mx : last tooth removed

8/15/2017 30smile

3. What causes support problems?

(associated with contour of ridge)

Lack of ridge support {RRR}

Mx : optimal border extension in depth & width, denture adhesives

8/15/2017 31smile

Fibrous displaceable ridge – denture sink in

on mastication

Mx : reline / rebase, optimal Occlusal

balance8/15/2017 32smile

Bony prominence covered by thin mucosa

(midline suture, tori , posterior nasal spine)

Mx : relieve denture

8/15/2017 33smile

Symptoms :

Pain

Altered sensation

Difficulty in swallowing & chewing

Why denture casues discomfort?

1. Defect in impression surface

2. Defect in polished surface

3. Defect in Occlusal surface

8/15/2017 34smile

1. Defects in impression surface

Sharp acrylic nodule

Undercut areas & attachments not relieved

Over extension

Deep post dam- sore throat, difficulty in

swallowing

Lower knife edged ridge

Mx : PIP & trimming, use of permanent soft

liners

2. Defects in polished surface

thick distobuccal flange of upper denture

Mx : PIP & trimming

8/15/2017 35smile

8/15/2017 36smile

3. Defects in occlusal surface

Premature contacts – pain on eating

CR not coinciding with MIP – pain &

ulceration lingual to lower anterior

ridge

Insufficient incisal over jet – pain /ulceration on

labial aspect of lower ridge

Mx : selective grinding, trimming, heal ulcer(avoid

denture wearing 1 day)

8/15/2017 37smile

Excessive VD

Mx : VD >2mm – remake denture

Insufficient over jet – cheek/lip biting

Mx : posteriorly buccal cusps rounded,

anteriorily lower incisors corrected

Teeth placed lingual to lower ridge – tongue

biting

Mx : remove lower lingual cusps

Symptoms :

Insufficient tooth visiblity

Too much tooth visibility

Creases at corner of mouth

8/15/2017 44smile

Excessive tooth visibility

8/15/2017 45smile

Causes for insufficient / excessive tooth

visibility

1. Improper orientation of Occlusal plane

2. Improper VD

3. Improper labiolingual & labiopalatal

positioning of anterior teeth

Mx : remaking denture

Patient consent need to be taken for aesthetics

during try-in

Creases at corner of mouth

1. Decreased labial fullness

2. Decreased VD

Mx : remake denture

1. Speech problems

2. Difficulty in eating

3. Clattering of teeth while eating & speaking

4. Altered taste

5. Nausea & gagging

6. Fibrous hyperplasia

7. Microbial infections

8. Soft tissue irritation

8/15/2017 49smile

SPEECH PROBLEMS

1. Problem with sibilants “S”

- Tooth contact on saying “S” due to

increased VD & excessive overbite

2. Problem with bilabial sounds “P” & “B”

- Incorrect VD & incisor position

3. Problem with labiodentals “F” & “V”

- Incorrect VD & upper anterior placed too far

back

8/15/2017 50smile

EATING DIFFICULTY

1. Instability

2. Posterior teeth trimmed more

3. Incorrect VD

CLATTERING OF TEETH WHILE SPEAKING &

EATING

1. Increased VD

2. Increased incisor overlapping

3. Loose denture

4. Cuspal interference

5. Use of porcelain teeth

8/15/2017 51smile

ALTERED TASTE

1. Acrylic reduces thermal conductivity

2. Alternative with metal base

NAUSEA & GAGGING

1. Loose denture

2. Poor occlusion

3. Thick distal terminal of upper denture & overextended posterior border of upper denture

4. Palatal placement of upper posterior

5. Psychogenic (fear of aspiration of denture & saliva pooling)

6. Prefer atropine & sedatives at initial period of denture use

8/15/2017 52smile

Whistling- high vault palate

Ear ache – decreased VD & Occlusal

prematurities

Food & saliva under denture

Drooling of saliva – decreased VD

Inability to eat meat

Allergy

Denture insertion appointment is very important in

delivering a functional & aesthetic denture to the

patient. More important is the need for the patient

to understand the limitations of the denture service

& to comprehend the use &care of dentures.

Dentist need to spend time in educating &

recalling the patient for complete denture as it will

lead to success of denture!

Success of complete denture treatment depends on relievingcomplaints which are posed at different time intervals..
