Q

What is the most common cause of FDP failure?

A

Caries

  • Mean life span is 10 years
  • 15% abutments will require RCT

Q

For implant retained FDP - what are the advantages of splinting them together?

A
  • Eases fabrication/delivery
  • Strong sytem

If abutments are parallel then you do not have to splint them together - this aids in hygiene…

Q

What are indications for Removable Dental Prosthesis?

A
  1. Long spans
  2. Correct Large Ridge Defects
  3. Minimally Invasive
  4. Proven Cost Effective Treatment
  5. Endodontically treated abutments 4x more likely to fail
17
Q

What happens to bite force when one wear an RDP?

A
  1. Bite force decreased from 200 psi to 50 psi

2. Masticatory efficiency decreased

18
Q

What are some consequences of using an RDP?

A
  1. Abutment teeth need constant repair (60% at 5 years, 80% at 10 years)
  2. Increased mobility, plaque, BOP and caries on abutment teeth.
  3. Abutment tooth loss of 44% within 10 years
  4. Accelerated bone loss in edentulous regions
19
Q

What are some considerations for a prosthesis extending from 7-10?

A
  1. Arch curvature
  2. Cantilever Length
  3. Residual Ridge
  4. Pontic Site
  5. Canine Stability
20
Q

For D extension what are your treatment options?

A
  1. RDP
  2. Removable Partial Overdenture
  3. Implant Retained FDP
21
Q

For D extension, RDP is most conventional treatment - you will have success if you have…

A
  1. Proper survey & design
  2. Adequate Abutments
  3. Broad Stress Distribution
  4. Well Adapted Bases
  5. Altered Cast Impression
22
Q

What are some advantages of a removable partial overdenture?

A
  1. Stability/Retention
  2. Bone Preservation
  3. Diminished Forces to Abutment Teeth
  4. Improved Tissue Health
23
Q

What 2 things must be present when evaluating a patient for a FDP/distal extension?

A
  1. Sufficient Bone
  2. Enough Restorative Space

-assuming occlusion is stable-

24
Q

What 3 options can you deliver to a patient with complete edentulism?

A
  1. Conventional Complete Dentures
  2. Overdentures
  3. Fixed-Detachable (Hybrid)
25
For overdentures, what percent are unstable on the mandible?
50%!
26
What is a hybrid prosthesis?
4-5 implants between mental foramina No soft tissue contact Implants placed on the mandibular arch better aid for the speech of the patient
27
For a hybrid prosthesis, you can cantilever up to how much?
1.5 to 2 X AP spread
28
Are implants successful in patients whose periodontal disease has been controlled?
Yes!
29
What is the optimum crown to root ratio?
2:3
30
What is the minimal crown to root ratio?
1:1
31
What are 3 advantages of an RDP?
1. Predictable 2. Cost-Effective 3. Esthetic
32
For a shortened life expectancy what is likely the best treatment option?
Removable :(
33
For patients with caries index/oral hygiene limitations what is your go to option?
Removable IS the only appropriate option
34
If you could travel in the future an look side to side to what removable appliances people were wearing - what would you see?
Implant Supported RDPs/Dentures
