Implant Assisted RPD Flashcards
What are indications for RPD therapy?
- Long Span Edentulous Area
- No abutment posterior to edentulous space
- Reduce Periodontal Support
- Need for cross arch stabilization
- Excessive bone loss within residual ridge
- Esthetics
- Immediate need to replace teeth
- Patient desire
What are some benefits regarding patient preferences to an Implant Fixed Prosthesis?
- Stability
- Chewing Ability
- Feels like it’s “part of me”
- Ease of cleaning
- Esthetics
- Preferred more by age 50+
What are some advantages and indications of implant assistance?
- Distal Extension Support
- Reduced Bone Resorption
- Elimination of unesthetic retentive elements
- Decreased stress on abutments
- Improved comfort and patient satisfaction
Does having an implant reduce the rate of bone resorption?
Yes!
What are some indications of implant assistance?
- Esthetics
- Oral Hygiene
- Extensive Ridge Defects
- Financial Limitations
- Extension Base Applications
What are some disadvantages of implant assistance?
- Additional Treatment Cost
- Additional Surgical Procedure
- Extended Treatment Time
- Careful Treatment Planning and Interdisciplinary Approach Required
- Technique Sensitive
- Additional Maintenance
- Manual Dexterity Required
What are the 3 Classifications for partially edentulous ridges?
- Kennedy
- McDermott
- Schneid and Mattie
What is the McDermott Classification?
- A modification of the Kennedy Classification
- Indicates arch configuration, and natural tooth abutment location
What is the Schneid & Mattie Classification?
- A modification of the Kennedy Classification
- Indicates arch configuration, and implant location
Describe the 4 classifications of Schneid & Mattie…
Class 1-I: Bilateral distal extension
Class 2-I: Unilateral distal extension
Class 3-I: Unilateral with implant mesial to natural tooth in posterior
Class 4-I: Bilateral anterior (like 22 & 27)
What are 3 elements in design for implant supported RDPs?
- Support (Soft Tissue Supports)
- Retention (Retains the Prosthesis)
- Stability (No Rocking)
What are some design considerations for implants?
- Quality
- Length
- Diameter
- Internal or External Hex
- Attachments
- Vertical Stops
What are some design considerations for implant supported RDPs?
- Rest Seats
- Direct Retainers
- Indirect Retainers
- Tooth Replacements
- Occlusion
- Heights of Contour
- Major Connector
- Minor Connectors
What are the 8 clinical procedures for an implant supported RDP?
- Diagnostic Mounting
- Diagnostic Setup
- Survey & Design
- Implant Placement
- Final Survey & Design
- Framework Try-In
- RPD Placement
- Pickup Locators
What does follow up care look like for these patients?
- 6-12 month prosthodontics evaluation
- 4-12 month prophylaxis
- Relines as needed
- Replacement of resilient attachments
- Reattachment of loose housings
