denture problems Flashcards
What are the 6 most common problem areas?
- discomfort
- looseness
- speech
- appearance
- miscallenaous
Discomfort and pain can be related to which 4 aspects of the denture?
- impression (fitting) surface / periphery
- polished surfaces
- occlusion
- other causes
Discomfort & Pain related to impression surface or periphery:
What is the cause of areas being painful to pressure (pain when denture is pressed)?
- inaccurate impression
- damaged cast
- warped denture base
- lack of relief over bony prominences
- ‘sharp ridges’
- other pathology (e.g: retained root)
Discomfort & Pain related to impression surface or periphery:
If the pt is experiencing areas which are painful to pressure, how would this be managed and avoided?
- PIP application to identify the area of pressure
- grind the denture fitting surface to relieve
- check for any other pathology
can be avoided by considering special impression techniques and implants
Discomfort & Pain related to impression surface or periphery:
Which 2 causes would mean the pt is experiencing pain on insertion / removal with signs of an inflamed mucosa or ulcer on the side of ridge?
- denture not relieved in the region of undercut
- incorrect path of insertion / removal being used by pt
Discomfort & Pain related to impression surface or periphery:
How would you manage a pt who is experiencing pain on insertion / removal and showing signs of an inflamed mucosa or ulcer on the side of ridge?
- use PIP to identify area of pressure or interference on insertion
- watch the pt insert and remove the denture
- relieve by grinding denture and instruct on insertion / removal
Discomfort & Pain related to impression surface or periphery:
What would cause the pt to have discrete painful areas and mucosal reddening / ulceration?
acrylic pearls or sharp fins as a result of an inappropriate technical finish
Discomfort & Pain related to impression surface or periphery:
How would you manage a pt experiencing discrete painful areas, mucosal reddening and ulceration?
Identify the area of the defect by running cotton wool over the fitting surface (area will snag).
Discomfort & Pain related to impression surface or periphery:
Why would a pt be experiencing pain on swallowing or in the distolingual area of the mandible (myolohyoid ridge)?
- overextended impression
- lack of relief
- inadequate communication with technician
Discomfort & Pain related to impression surface or periphery:
How would you manage a pt complaining of pain on swallowing or in the distolingual area of the mandible?
Palpate the mucosa and ridges and relate to the denture using PIP. Relieve by grinding denture.
Discomfort & Pain related to impression surface or periphery:
Why would a pt be experiencing soreness / redness around the denture peripheries?
overextended impressions / design error - results in a lack of relief for frenae or muscle attachments.
Discomfort & Pain related to impression surface or periphery:
How would you manage a pt CO soreness or reddening around the denture peripheries?
- manipulate the border tissues to identify overextension
- denture may be displaced or tissue may blanch
- PIP helps to identify areas of overextension
Discomfort & Pain related to impression surface or periphery:
Why might a pt be experiencing pain or ulceration along the posterior border of the upper denture?
Due to the potsdam being too deep caused by inappropriate preparation of the master cast.
Discomfort & Pain related to impression surface or periphery:
How would you manage a pt complaint of pain or ulceration along the posterior border of the upper denture?
reduce with caution - advise the pt about increased denture looseness, may need to add new post dam.
Discomfort & Pain related to impression surface or periphery:
What would cause generalised pain over the entire denture supporting area for which the pt modifies the denture by filling it with soft material?
underextended base - due to inadequate impression, over adjustment of denture or impression surface.
