CCA Adhesives & Retention Systems

Question 1

What is the primary adhesive type used for securing craniofacial prostheses to facial skin?

Accepted Answer

Medical-grade silicone adhesives

Answer

Medical-grade silicone adhesives are the standard of care for craniofacial prostheses due to their biocompatibility, flexibility, and compatibility with silicone prosthetic materials.

Question 2

Which property of a prosthetic adhesive is MOST important for patient comfort and long-term skin health during extended daily wear?

Accepted Answer

Vapor permeability

Answer

Vapor permeability allows moisture and perspiration to escape through or around the adhesive layer, preventing skin maceration and breakdown beneath the prosthesis.

Question 3

What is the recommended application method for medical adhesive when fitting a facial prosthesis?

Accepted Answer

Application to both the prosthesis margin and the corresponding skin area, allowing each coat to become tacky

Answer

Applying adhesive to both the prosthesis margin and the skin, then allowing each coat to become tacky before joining, creates a stronger contact bond and optimal retention.

Question 4

Which solvent is most commonly recommended for removing medical-grade silicone adhesive residue from facial skin?

Accepted Answer

Medical adhesive remover (silicone solvent-based)

Answer

Dedicated medical adhesive removers formulated with silicone-compatible solvents are most effective and least irritating for dissolving silicone-based adhesive residue from skin.

Question 5

Which factor MOST adversely affects adhesive bond strength in facial prosthetic retention?

Accepted Answer

Skin oils, perspiration, and surface moisture

Answer

Skin oils, perspiration, and moisture create a barrier between the adhesive and the skin surface, significantly reducing bond strength and causing premature prosthesis detachment.
