Treatment Planning Flashcards
(34 cards)
What are 2 good factors NOT to place implants?
- Lack of bone
2. Lack of restorative space
What are some patient limitations regarding implant placement?
- Surgical Risk
- Disease
- Hygiene
- Available Treatment Time
What are 4 indications for tooth replacement?
- Esthetics
- Phonetics
- Function
- Occlusal Stability
What are 9 factors in influencing selection of pros treatment planning?
- Length of Edentulous Span
- Distal Extension
- Complete Edentulism
4, Periodontal health - Radiographic Crown:Root Ratio
- Extensive Bone Loss of Residual Ridge
- Shortened Life Span Expectancy
- Caries Index/Oral Hygiene Limitations
- Patient Desires/Economic Consierations
For a short edentulous span think…
Implants/Fixed/Removable
For a medium edentulous space think…
Implants/Fixed
For a long edentulous space think…
Removable
When missing a single tooth you can restore with:
- Implant
- Conventional FDP
- Resin bonded FDP
- Removable Dental Prosthesis
Are single tooth implants successful?
Yes!
- 97% 10 years
- Low caries
- Improved hygiene
- Decreased abutment tooth loss
- Psychological Advantage
For the posterior what is the max amount of pontics you would desire?
2
For the anterior what is the max amount of pontics you would desire?
4
What is the most common cause of FDP failure?
Caries
- Mean life span is 10 years
- 15% abutments will require RCT
How much distance would one want between implant and tooth?
1.5 - 2 mm
How much distance would one want between implants?
3 mm
For implant retained FDP - what are the advantages of splinting them together?
- Eases fabrication/delivery
- Strong sytem
If abutments are parallel then you do not have to splint them together - this aids in hygiene…
What are indications for Removable Dental Prosthesis?
- Long spans
- Correct Large Ridge Defects
- Minimally Invasive
- Proven Cost Effective Treatment
- Endodontically treated abutments 4x more likely to fail
What happens to bite force when one wear an RDP?
- Bite force decreased from 200 psi to 50 psi
2. Masticatory efficiency decreased
What are some consequences of using an RDP?
- Abutment teeth need constant repair (60% at 5 years, 80% at 10 years)
- Increased mobility, plaque, BOP and caries on abutment teeth.
- Abutment tooth loss of 44% within 10 years
- Accelerated bone loss in edentulous regions
What are some considerations for a prosthesis extending from 7-10?
- Arch curvature
- Cantilever Length
- Residual Ridge
- Pontic Site
- Canine Stability
For D extension what are your treatment options?
- RDP
- Removable Partial Overdenture
- Implant Retained FDP
For D extension, RDP is most conventional treatment - you will have success if you have…
- Proper survey & design
- Adequate Abutments
- Broad Stress Distribution
- Well Adapted Bases
- Altered Cast Impression
What are some advantages of a removable partial overdenture?
- Stability/Retention
- Bone Preservation
- Diminished Forces to Abutment Teeth
- Improved Tissue Health
What 2 things must be present when evaluating a patient for a FDP/distal extension?
- Sufficient Bone
- Enough Restorative Space
-assuming occlusion is stable-
What 3 options can you deliver to a patient with complete edentulism?
- Conventional Complete Dentures
- Overdentures
- Fixed-Detachable (Hybrid)
