Question 1

Which retention system uses a milled bar connected between two or more implants over which a corresponding clip on the prosthesis engages?

Accepted Answer

Bar-clip retention

Bar-clip retention uses a custom-milled bar spanning multiple implants with a matching clip housed in the prosthesis for secure attachment.

Question 2

When planning implant placement for an auricular prosthesis, which anatomical landmark is most critical to avoid?

Accepted Answer

Mastoid air cells

Answer

Mastoid air cells must be avoided during auricular implant placement to prevent communication with the middle ear and risk of infection.

Question 3

What is the recommended minimum bone volume at a craniofacial implant site to ensure osseointegration?

Accepted Answer

4–5 mm depth

Answer

A minimum bone depth of approximately 4–5 mm is generally required for adequate craniofacial implant osseointegration and stability.

Question 4

Which magnetic retention component is housed within the prosthesis and attracted to a corresponding keeper on the abutment?

Accepted Answer

Rare-earth magnet cassette

Answer

The rare-earth magnet cassette is embedded in the prosthesis and attracted to a ferromagnetic keeper seated on the implant abutment.

Question 5

A patient presents with hypergranulation tissue at the percutaneous implant site. What is the FIRST recommended management step?

Accepted Answer

Increased cleaning frequency with chlorhexidine

Answer

Hypergranulation at the skin-implant interface is initially managed by intensifying hygiene with chlorhexidine before considering more invasive interventions.
