Question 1

Which retention method for a silicone auricular prosthesis relies on direct bone-anchored implants placed by a surgeon?

Accepted Answer

Osseointegrated implants with bar/clip attachments

Answer

Osseointegrated implants placed in the temporal bone allow bar-and-clip or magnet retention systems that eliminate the need for skin adhesives.

Question 2

During the wax try-in stage for a nasal prosthesis, the primary purpose is to:

Accepted Answer

Evaluate form, fit, symmetry, and patient acceptance before processing

Answer

The wax try-in allows the anaplastologist and patient to assess shape, margins, symmetry, and color harmony before committing to final processing.

Question 3

Intrinsic coloring of a silicone prosthesis refers to:

Accepted Answer

Incorporating pigments into the silicone base before vulcanization

Answer

Intrinsic coloring embeds pigments within the silicone mass so color is durable and cannot be rubbed off, unlike extrinsic surface painting.

Question 4

A two-part rigid stone mold for a silicone prosthesis must be sealed with a separating medium primarily to:

Accepted Answer

Prevent mold sections from bonding to each other and to the silicone

Answer

Separating medium (e.g., petroleum jelly or alginate separator) prevents adhesion between mold halves and between mold and silicone, enabling clean separation.

Question 5

When fabricating an ocular prosthesis, the iris disc is typically positioned to match the patient's contralateral eye primarily by aligning:

Accepted Answer

Pupil center relative to the geometric center of the prosthesis and overall iris diameter

Answer

Accurate placement of the pupil center and correct iris diameter are the primary factors for achieving natural-appearing gaze alignment in an ocular prosthesis.
