RMTL 3 - Immediate dentures (complete)

Question 1

What are the advantages of immediate dentures?

Answer 1

Quick fix

Patient never left without teeth

Question 2

What are the disadvantages of immediate dentures?

Answer 2

Design is predication of ridge form after teeth extracted

Rapid resorption after extraction - means new dentures or rebase

Question 3

If there are undercuts in the anterior ridge form for a denture, how is this overcome?

Answer 3

Avoid = alter POI, don’t put acrylic in this area, compromise extensions
Remove undercut

Question 4

What are the options for severely undercut ridges

Answer 4

• Open faced –> Doesn’t use a buccal flange, avoids surgery, can give good aesthetics – teeth look as if they are emerging from gingivae naturally. No buccal coverage, can get rapid resorption resulting in flabby ridge therefore NEVER in mandible.
• Part-flange – FLANGE FINISHES AT MAXIMUM BULBOSITY OF ALVEOLAR RIDGE, to the maximum convexity of the ridge, aesthetics/food trapping may be a problem (if pt has high smile line)
• Remove or reshape ridge = Alveolotomy – reshape / alveolectomy - remove

Question 5

What is the after care of socketing/open face?

Answer 5

Immediately

• Compression of sockets/ haemostasis
• Normal POIG
• Dentures in place for first 24 hours = inflammation/ swelling occurs due to trauma – if the denture is removed within 24hrs the gingivae will have swollen so much that the denture cannot be re-inserted
• Less of an issue if there are only few teeth being added to the denture

24-hour examination

• Remove dentures, saline rinse
• Check haemostasis/clots
• Adjustments
• Patient instructions regarding removal and cleaning

Review at 1 week – KEEP DENTURES IN AT ALL TIMES (EXCEPT CLEANING)
- Further adjustment or Suture removal (if applicable)
