Q

5 case selection criteria for immediate replacement dentures?

A
  1. Leave only straight forward extractions for IR - surgicals not ideal.
  2. May need to coordinate around sedation or even GA appointments.
  3. Always advise patient before starting treatment that denture will become loose and will require replacement - FINANCIAL IMPLICATION.
  4. Require regular review.
  5. Can patient cope (financially, physically and emotionally).

Q

What is a case we would consider an OPEN FACE immediate replacement denture?

A
  • BULKY UPPER ANTERIOR ALVEOLAR RIDGE.
  • Cannot utilize undercuts for retention as too deep.

A

Would cause denture instability.

18
Q

6 instructions to give to the lab for immediate dentures?

A
  • Which teeth are to be extracted.
  • Arrangment.
  • Shade
  • Flange type (part. full, flangeless).
  • Material.
  • Date for denture insertion/ extractions.
19
Q

When setting teeth in wax for immediate dentures, why do we do one side and then the other?

A

Help judge:
- Incisal level
- Labial fullness

20
Q

What must be done prior to extracting teeth for immediate dentures?

A

BEFORE giving LA check that dentures are ready and have correct teeth added on.

21
Q

2 things to be mindful with when trying in immediate dentures right after extraction?

A
  • Removing and re placing dentures often as that can cause bleeding from sockets.
  • Placing the denture in with too much force as it can b hard to remove + may cause trauma.
22
Q

Why do we ideally want patients to wear IR for 24 hours after insertion?

A
  • To prevent the tissues from swelling overnight and patient unable to reinsert them in the morning.
23
Q

Aftercare for IRs (4)?

A
  • Dentures to be kept in for 24hrs - post op instructions.
  • Review appointment ideally on day after insertion.
  • After 24 hr: warm saline mouthwash for full week post extraction.
  • Patient should remove denture after meals, rinse mouth and clean denture (soft toothbrush, soap and water).
24
Q

What do we check in the review appointment after extractions for IR?

A

If the day after:
- Check for healthy clots in the sockets.
- Identify any areas of inflammation and ease denture.
- Check for trauma around sockets and in the sulci.

25
Q

What are the review appointment timings for IRs?

A
  • 1 day
  • 1 week
  • 1 month
  • 3 months (if managing ok)
  • 6 months
26
Q

What is done in the review appointment 1 week post extraction?

A
  • Further adjustment as required.
  • Check occlusion.
27
Q

What is done in the review appointment 1 month post extraction?

A
  • Assess adaptation.
  • Consider temporary reline.
28
Q

What is done in the review appointment 3 months post extraction?

A
  • Assess how well the patient is coping.
  • If patient coping well then 6 months recall.
29
Q

What is done in the review appointment 6 months post extraction?

A
  • Consider tissue conditioner, rebase or replace denture.
30
Q

Two cases where a ONE STAGE immediate denture may be required?

A
  • Trauma to anterior teeth.
  • failed post-crown.
31
Q

What is different in the process of making a ONE STAGE immediate denture?

A
  • no second imps.
  • no TRIAL/ TRY IN STAGE .
32
Q

5 steps to ONE STAGE immediate dentures.

A
  1. Upper and lower impressions recorded (+ check for accuracy and full extension).
  2. Wax squash bite if required to confirm occlusion.
  3. Choose shade.
  4. Prescription to laboratory including design.
  5. Extraction and insertion of denture at next visit.
33
Q

3 treatment options for patient who lost both central incisors?

A
  • Bridge.
  • Implants
  • Denture
34
Q

7 clinical stages for IR dentures?

A
  1. Examination and assessment (teeth to be removed - clinically and radiographically).
  2. Impressions (alginate in stock trays - check accurate and fully extended).
  3. Occlusion (index teeth may be present).
  4. Design (usually simple acrylic plate as it will likely need replaced in the future).
  5. Second impressions (special trays).
  6. Try-in (limited to the teeth already missing).
    - Check (extensions, occlusion, shade - Make sure the patient is happy with it.
    - Prescribe to laboratory - mark X on models the teeth to be extracted + write it on lab card.
  7. Extractions & Finish (care with extractions and insertion of denture).
    - Check the denture BEFORE giving LA for extractions.
