CIT Anatomy & Physiology Fundamentals 3

Question 1

Which cell type is primarily responsible for resorbing bone during the remodeling phase after implant placement?

Accepted Answer

Osteoclasts

Answer

Osteoclasts are multinucleated cells that resorb bone through acidification and enzymatic breakdown, playing a key role in bone remodeling.

Question 2

The nasopalatine nerve and vessels exit the oral cavity through which foramen?

Accepted Answer

Incisive foramen

Answer

The nasopalatine nerve and vessels pass through the incisive foramen located in the anterior hard palate behind the central incisors.

Question 3

Which anatomical structure forms the roof of the maxillary sinus?

Accepted Answer

Orbital floor

Answer

The floor of the orbit forms the roof of the maxillary sinus, which is why orbital complications can arise with aggressive sinus surgery.

Question 4

Biologic width in relation to implants refers to the combined dimension of which two soft tissue components?

Accepted Answer

Junctional epithelium and connective tissue attachment

Answer

Biologic width around implants consists of the junctional epithelium (~2mm) and the supracrestal connective tissue attachment (~1mm) that form a soft tissue seal.

Question 5

Which muscle attaches to the medial surface of the mandibular ramus and is responsible for jaw closure?

Accepted Answer

Medial pterygoid

Answer

The medial pterygoid muscle attaches to the medial surface of the mandibular angle and ramus, acting as a jaw elevator (closure muscle).
