Removable Pros Flashcards
Define, a partial or complete denture inserted on the same day as the tooth or teeth are removed.
Immediate denture
What are the 5 main advantages of immediate dentures?
- Aesthetics
- Speech
- May maintain function
- Avoid drifting/tilting of remaining teeth
- Self esteem
What are the two main disadvantages of immediate dentures?
- A space is likely to develop between the denture and ridge as healing occurs
- May need replaced after initial resorption
After what timeframe will immediate dentures normally need replaced?
After 6 months
What are the 4 key post-op instructions for IR dentures?
- Dentures to be kept in for 24 hours
- After 24 hours, advise warm saline mouthwash and for pt to remove denture after mealtimes
- After 24 hours, rinse mouth and clean denture using soft denture brush, soap and water.
- Review appointment will be made one day after insertion
At the next day review appointment for IR dentures, what should be assessed?
- Examine mouth for healthy clots
- Identify areas of inflammation and ease denture accordingly
What 8 landmarks should be identifiable in an upper impression?
- Labial sulcus
- Labial frenum
- Palatine rugae
- Buccal sulcus
- Hamular notch
- Tuberosity
- Buccal frenum
- Incisive papilla
What 7 landmarks should be identifiable in a lower impression?
- Labial sulcus
- Labial frenum
- Buccal frenum
- Lingual sulcus
- Buccal shelf
- Buccal sulcus
- Lingual frenum
Name 6 ways you can solve denture design problems?
- Modification of survey lines
- Combining fixed and removable prosthodontics
- Precision attachments
- Two-part denture
- Swing lock denture
- Specific dentures for bruxists
In what situation might a two-part denture be utilised?
When there’s gross tissue loss & different paths of insertion
When might a swing-lock denture be useful?
For partial lower dentures, usually Kennedy class I, when there are no suitable undercuts for gaining retention of the denture.
How does a swing-lock denture work?
It has additional flange on the labial aspect of lower anterior teeth which engages bone and tissue undercuts (basically acts like a gate)
In what 6 ways can a denture be modified to be more suitable for a bruxist and reduce the risk of fracture?
- Metal backing to anterior teeth
- Co/Cr connector
- Metal occlusal surfaces (extend Co/Cr over these surfaces)
- Use of a cross-linked teeth (for better wear resistance)
- Acrylic postdam (increased retention)
If an error in occlusion occurs at try-in stage, the LHS occludes but the RHS has a posterior open bite, and the FWS is correct when checked, what does this mean? And how is it fixed?
- if FWS is correct, the occluding teeth on left are maintaining an appropriate OVD, so the teeth on the right need to be lowered into occlusion.
- You can do this by adding wax over the teeth on the right to the correct level so that it occludes. You can re-record the occlusion, asking the technician to re-articulate the casts and then reset teeth at new occlusion. Pt would be booked in for further retry.
If an error in occlusion occurs at try-in stage, the LHS occludes but the RHS has a posterior open bite, and there is inadequate FWS when checked, what does this mean? And how is it fixed?
- it would suggest that the occluding teeth on RHS are propping the bite open.
- you would need to remove the occluding teeth that are holding the OVD, replace with wax at chairside, build up a new wax block (record block). Establish correct OVD, re-record occlusion and get the teeth reset for retry.
When is the denture review/ease appointment normally arranged after the fit appointment?
48-1 week after fit appointment
If a patient complains that their dentures move, what clinical step should you take to assess this?
Assess adaptation of denture by applying vertical pressure onto tissues and seeing ion denture rocks.
If a patient complains that their dentures move, what 2 clinical steps could you take to try and remedy this?
- Re-lining fit surafce
- Relieving area of frenum or shortening flange extensions
If a patient complains that their jaw hurts at the denture review appointment, what might be the cause of this?
Change in OVD, always re-check FWS.
After how long should full ridge healing take after XLA?
6 months
