WHY DO PATIENTS TAKE TIME TO
ADAPT SPEECH?

WHY DO PATIENTS TAKE TIME TO
ADAPT SPEECH?
• Muscle memory of the Tongue and Soft
Tissues
• Lip Support changes
• Vertical dimensions changes
• Palatal and Teeth contour changes
• Stability of new denture
• Sensory perception changes
MUSCLE MEMORY OF TONGUE AND
SOFT TISSUES
• Tongue is used to contacting certain areas in the
oral cavity to produce certain sounds
• contact areas may changes due to more
“bulky” dentures
• Examples: “sss” sounds
LIP SUPPORT CHANGES
• Lips needs to do certain movement to produce
certain sounds
VERTICAL DIMENSION CHANGES
• Vertical dimensions of new denture and denture
teeth may cause difficulties
• example: “ff” sounds
PALATAL AND TEETH CONTOUR
• New denture = new palatal and teeth contour
• Patient’s tongue needs to get used to
contacting new areas in the mouth to produce
speech
STABILITY OF NEW DENTURES
• Patient needs to stabilize the denture during
speech leading to disturbance in the speech
SENSORY PERCEPTION CHANGES
• The tongue cannot feel the roof of the mouth or
the denture teeth
• This can affect the speech as it takes time for the
patient to get used to it

OVERVIEW
• Dentures are less efficient of natural teeth
• Ability to eat all foods is the exception
• A better ridge equals less problems
• Minimal ridge
• denture movement – less chewing efficiency
• Especially mandibular movement
• sore spots

CONCLUSION
• Close co-operation between the patient, physician
and dentist is key to maintaining and ensuring the
continued success of a great fitting denture!!!

1. WHY IS IT IMPORTANT?
2. BRUSHING
3. COMMERCIAL CLEANERS
4. ULTRASONIC CLEANERS
5. MUCOSAL HYGIENE
WHY IS IT IMPORTANT?
• Plaque forms on dentures the same as it does on natural
teeth
• Want to keep the tissues underneath the denture healthy
• Increases the longevity of the denture
• Maintains the fit of the denture over time
• Helps prevent staining and denture odor
BRUSHING
• Most effective and affordable cleaning method
• Use a soft, long bristled toothbrush
• Use a non-abrasive cleaning agent
• Dish soap
• Denture cleaner
• Advise patients to brush both sides, and especially along junction
of denture teeth and base
• Brush over a basin of water to avoid dropping and damaging
denture
COMMERCIAL CLEANERS
• A good adjunct to brushing
• Advise patient to soak denture in cleaner overnight – 1530 minutes is NOT effective
• This would also encourage patients to remove their
denture overnight!
• Soaking helps clean out bacteria caught in the pores of
the denture that cannot be removed by brushing
• Combination of brushing and soaking is best
ULTRASONIC CLEANERS
• Effective cleaning method
• ‘Sonic’ cleaners are not effective without a chemical cleaner
• Patient should be advised that having the denture cleaned
only during dental appointments is not adequate!
MUCOSAL HYGIENE
• Important to educate patients about the necessity
of cleaning their mucosal tissues
• Healthy tissues are essential for a proper fit and
comfortable denture
• Mucosa should be brushed twice daily
• Brush with a soft bristled brush or washcloth and
warm water
• Massaging tissues will stimulate blood flow and
improve the health of the tissues
WHAT MAKES A POOR
RIDGE?
Dr. Lozowski’s Group: Sean, Joey, Angela,
Amanda, Katrina, Alicia
WHAT MAKES A POOR RIDGE?
• Decreased height
• The more height you have, the more retentive the
ridge
WHAT MAKES A POOR RIDGE?
• Small size
• The wider the ridge, the more retentive
WHAT MAKES A POOR RIDGE?
• Boggy tissue
• Loose tissue will cause movement of the denture
• Firm, non-compressible tissue (especially in the
palate) is ideal
WHAT MAKES A POOR RIDGE?
• Excessive undercuts
• Surgery may be required to remove excessive
undercuts or huge tuberosities that are inhibiting
suction
• A good ridge has no undercuts
WHAT MAKES A POOR RIDGE?
• Large tori
• Surgery may be required to remove large tori that
are inhibiting proper impressions and seating
THE IDEAL RIDGE
•
•
•
•
•
•
Adequate bone support
Bone covered by adequate soft tissue
No undercuts or hanging protuberances
No sharp ridges
Adequate buccal and lingual sulci
Satisfactory relationship between maxilla and
mandible
WHY DO PATIENTS TAKE
TIME TO ADAPT TO
CHEWING?
ALLIE, TATUM, JORDAN, TALAL, DAN AND GURJOT
NEW DENTURE PATIENTS
•
•
•
•
•
•
Lack of proprioception
Loss of vertical dimension
Maxillary to mandibular relationship
Tooth position
Neuromuscular adaptation
Tissue adaptation
REPLACEMENT DENTURES
•
•
•
•
Changes in occlusion
Change in centric relation
Change in cuspal inclination
Tissue adaptation
PATIENTS MAY EXPERIENCE
•
•
•
•
•
•
Pain
Decreased efficiency
Initially cheek or lip biting
Discomfort
Muscle fatigue
Changes in salivary flow
WAYS TO DEAL WITH THE ISSUES
• Placing food towards corners of mouth
• Cutting food into smaller pieces
• Initially eating soft foods
• Avoiding hot foods
• Encourage wearing dentures to get
use to them.
NEUROMUSCULAR ADAPTATION
• Muscles will be hyperactive at first
• Cheeks, lips, and tongue must be trained to
maintain the denture in position during mastication.
LIFETIME OF CHEWING!
