Question 1

Which instrument is most appropriate for trimming thin excess silicone during a chair-side prosthesis adjustment?

Accepted Answer

Razor blade or scalpel

Answer

A razor blade or scalpel allows precise, clean cuts on thin silicone edges without the tearing that scissors can produce in compliant materials.

Question 2

What is the recommended storage condition for a silicone facial prosthesis when not in use?

Accepted Answer

In a cool, dry container away from UV light

Answer

UV light is a primary accelerant of silicone degradation and color fading, so storage in a cool, dark, dry container maximizes prosthesis longevity.

Question 3

A patient returns with a cracked acrylic orbital prosthesis framework. What material is typically used to repair cracks in acrylic prosthetic bases?

Accepted Answer

Autopolymerizing (self-curing) acrylic resin

Answer

Autopolymerizing acrylic repair resin chemically bonds to existing acrylic bases and provides a durable, color-matched repair for cracked prosthetic frameworks.

Question 4

What is the clinical significance of a prosthesis with a poor marginal seal against the skin?

Accepted Answer

Risk of moisture ingress, skin irritation, and odor

Answer

A poor marginal seal allows moisture, bacteria, and debris to accumulate beneath the prosthesis, creating conditions for skin irritation, infection risk, and odor.

Question 5

How should a patient clean the abutment sites of an implant-retained auricular prosthesis?

Accepted Answer

Gentle brushing with a soft-bristle toothbrush and mild soap around the abutments

Answer

Gentle soft-bristle cleaning with mild soap removes debris and plaque around abutments without damaging implant components or peri-implant tissue.
