CCA Prosthetic Maintenance & Repair Flashcards

How frequently does a silicone facial prosthesis typically require replacement in clinical practice?

Answer: Every 1–2 years

Silicone facial prostheses typically require replacement every 1–2 years due to color fading, edge deterioration, and material stiffening from UV exposure and adhesive use.

What is the most common cause of edge breakdown in silicone facial prostheses during daily wear?

Answer: Repeated adhesive application and removal at the margins

The repetitive mechanical stress of daily adhesive application and removal at thin feathered margins causes progressive edge thinning and tearing over time.

Which adhesive type is most appropriate for an anaplastology patient who swims regularly?

Answer: Medical-grade silicone adhesive

Medical-grade silicone adhesives provide superior water resistance for patients who swim or perspire heavily compared to standard latex-based options.

What is the recommended method for removing prosthetic adhesive from patient skin?

Answer: Applying adhesive remover solvent, then gently lifting

Adhesive remover solvent safely loosens the bond without traumatizing fragile or reconstructed skin, unlike mechanical scrubbing or harsh solvents.

When a patient reports that their implant-retained prosthesis has become loose, what is the appropriate first clinical step?

Answer: Evaluate the retention clips or magnets for wear and replace if needed

Loose implant-retained prostheses are most often caused by worn retention clips or magnets, which can be replaced without fabricating an entirely new prosthesis.

What is the purpose of applying a protective coating to an extrinsically colored silicone prosthesis?

Answer: To seal surface pigments and extend color life

Protective coatings seal extrinsic pigments against UV degradation and mechanical abrasion, helping maintain color fidelity and extending prosthesis lifespan.
