CCA Prosthetic Fabrication & Fitting 1 — Questions and Answers
Question 1: What is the purpose of a wax trial in prosthetic fabrication?
- To harden the prosthesis
- To apply color permanently
- To evaluate and adjust shape before final fabrication (Correct answer)
- To test materials for allergy
Correct answer: To evaluate and adjust shape before final fabrication
A wax trial allows for adjustments in shape, fit, and aesthetics before final processing.
Question 2: Which technique ensures optimal fit during prosthesis fabrication?
- Manual sketching
- Color swabbing
- Custom impression molding (Correct answer)
- Prefabricated templates
Correct answer: Custom impression molding
Custom molding ensures the prosthesis conforms precisely to the anatomy for comfort and aesthetics.
Question 3: What is extrinsic coloring in prosthetics?
- Color mixed during molding
- Surface painting post-fabrication (Correct answer)
- Pigment used for surgical planning
- Dye added to adhesives
Correct answer: Surface painting post-fabrication
Extrinsic coloring is applied to the surface to match surrounding skin tone and refine appearance.
Question 4: What helps ensure long-term prosthesis retention?
- Cosmetic sealers
- Flexible tubing
- Retention systems like adhesives or implants (Correct answer)
- Lightweight fabric wrap
Correct answer: Retention systems like adhesives or implants
Using medical-grade adhesives, mechanical retention systems, or osseointegrated implants supports secure prosthesis fit.
Question 5: What is the final step in the prosthesis fitting process?
- Billing the patient
- Documenting patient history
- Final adjustments and patient approval (Correct answer)
- Selecting surgical options
Correct answer: Final adjustments and patient approval
The final fitting includes adjustment for comfort, alignment, and aesthetic validation by both clinician and patient.
Question 6: Why are follow-up visits important after prosthesis delivery?
- To increase visits
- To test unrelated conditions
- To ensure fit, function, and satisfaction (Correct answer)
- To initiate new treatments
Correct answer: To ensure fit, function, and satisfaction
Follow-ups ensure proper function, address issues, and allow updates for improved long-term satisfaction.
