Hints for Cleaning Dentures

• The patient should be instructed to remove the
  dentures after the meal and scrub them vigorously
  with soap before reinserting them (soap is mild
  and non abrasive).
• The mucosa in contact with the denture should be
  kept clean and massaged with a soft toothbrush.
• Patients with recurrent infections should be
  persuaded not to use their dentures at night but
  rather leave them exposed to air, which seems to
  be a safe and efficient means of preventing
  microbial colonization.

• Patients are routinely instructed to clean their
  dentures by light brushing with a soft, long
  bristled denture brush or a multifluted soft
  nylon brush with rounded ends and soap and water.
  
• The mechanical cleaning action of the brush is
  usually sufficient to remove loosely attached
  soft food debris, without abrading the denture
  base and teeth (but doesnt disinfect).
• The removal of hard calculus deposits, plaque,
  and stains require more vigorous measures such as
  the daily use of immersion chemical denture
  cleansers or brush-on diluted acid cleansers.

5

• dentures should be cleaned over a filled sink or
  a soft cloth to avoid damage in case the denture
  is dropped.
• Denture cleaners such as Polident should be used
  overnight to be effective.

Limitations of Dentures

• Dentures are less effective than natural teeth
• Some people experience difficulty eating some
  types of food sticky foods, biting apples
• The success of a patients denture is dependent
  on the quality of their anatomy

How long will my denture last? Do I have to come
back?

• Genevieve Poitras, Erin Power
• Kristian Richardson, John Rector

9
Life Expectancy

• Denture expected to last 5-7 years
• BUT if tissues change drastically they may need
  to be remade sooner (I.e) In the case of an
  immediate denture where tissues are healing.

10
Check Ups

• Check ups as needed until patient is comfortable
  (sore spots eliminated, occlusion fine tuned,
  etc)
• Yearly recall recommended
• Easier to monitor tissue changes and correct
  small problems
• Wear
• Fractures
• Resorption
• Review and reinforce proper hygiene
• Patient rapport

11
Limitations

• Less efficient than natural teeth
• Some foods may be more difficult to chew
• Movement increased chewing efficiency
  decreased (especially with smaller ridge)
• Decreased proprioception (no PDL)
• Sore spots (especially with small ridge)

Better to discuss limitations with patient prior
to delivering denture!

Patient with old denture - Why will it take
time to adapt chewing?

• Dr. Borans Group

13
Main Points

• Excessive saliva
• Foreign object in mouth, taste from denture
  material
• Change in occlusion
• Increase in vertical dimension, change in plane
  of occlusion,sharper teeth and occlusal cusps
• Learning new muscle movements
• Different tissue - acrylic interaction
• Develop sore spots, pressure in certain areas
  will cause a change in chewing habits

Dentures and Speech

15
Factors

• Muscles are working differently
• Thickness of the denture
• Relationship of the incisal edges to the lower
  lip
• Tongue Space
• Palatal contours
• Altering the dimension of occlusion

16
Relationship of the incisal edges to the lower lip

• Placing teeth too far lingual will make Ts sound
  like Ds and if too far labial Ds will sound
  like Ts
• May lead to whistling or a lisp

17
Tongue Space

• A cramped tongue space forces the tongue to form
  a small opening for the escape of air which will
  cause speech impairment
• Muscle memory re-learning speech patterns

18
Considerations

• Speech adaptation to a new denture takes 2-4
  weeks
• Patients whove become accustomed to their old
  dentures may have difficulty in learning new
  motor acts when receiving new dentures
• Patients themselves will notice their speech
  impairment more than anyone else

19
Tips

• Read out loud to get used to speaking e.g.
  reading the newspaper
• Design the denture to replicate the old one if
  theyre happy with it
• To identify the problem attempt to replicate the
  same distorted sound yourself
• Check the patients hearing, if they have a
  hearing problem it may prolong the adaptation
  period
• May refer to a speech pathologist

20
Limitations of Dentures

• Less efficient than natural teeth
• Some people can eat all foods easily, but that is
  the exception
• Depending on the ridge, the denture may move
  around in the mouth
• Esthetics - may vary from patients expectations
• Time consuming to make a denture

How and why to get tissues healthy

22
Why do we need healthy tissues?

• Better fit
• Patient comfort
• Improved denture function
• Better final impression
• Lower risk of infection

23

• When you see unhealthy tissues, think of the most
  common causes and try to tackle those problems
  first
• Common Causes
• Poor oral hygiene
• Occlusal disharmony
• Inaccurate denture bases
• Tissue abuse

24
Tissue Conditioning techniques

• Rest tissues at night
• Better hygiene
• Denture hygiene
• Soak denture overnight
• Brush inside AND outside of the denture
• Ultrasonic cleaning
• Tissue hygiene
• Tissue rest at least 8 hrs/day
• Massage tissue
• Tissue rest 24 hours prior to final impression
• Occlusal correction (localized)
• Temporary soft liners
