CIT Anatomy & Physiology Fundamentals 2

Question 1

Which nerve is most commonly at risk during posterior mandibular implant placement due to its course through the mandibular canal?

Accepted Answer

Inferior alveolar nerve

Answer

The inferior alveolar nerve runs through the mandibular canal and can be damaged if an implant is placed too close to or into the canal.

Question 2

The mental foramen is most commonly located inferior to which tooth?

Accepted Answer

Second premolar

Answer

The mental foramen is typically found inferior and slightly distal to the apex of the mandibular second premolar.

Question 3

Which type of bone is found predominantly in the cancellous (trabecular) region and is important for osseointegration?

Accepted Answer

Spongy bone

Answer

Spongy (cancellous/trabecular) bone contains marrow spaces with blood vessels that support early osseointegration through vascularization.

Question 4

The Schneiderian membrane refers to which anatomical structure relevant to sinus lift procedures?

Accepted Answer

Mucosal lining of the maxillary sinus

Answer

The Schneiderian membrane is the mucoperiosteal lining of the maxillary sinus that must be carefully elevated during sinus augmentation procedures.

Question 5

Which blood vessel supplies the majority of blood to the mandible and is relevant during implant surgery planning?

Accepted Answer

Inferior alveolar artery

Answer

The inferior alveolar artery accompanies the inferior alveolar nerve through the mandibular canal and is the primary blood supply to the mandibular teeth and bone.
