What is one of the functions of CBCT examination in treatment planning?

Designing a flap for apical surgery

Analyzing the anatomy of the tooth

Measuring the size of the lesion

Detecting nerve proximity to avoid nerve injury (correct)

What is the purpose of designing a flap during apical surgery?

To minimize exposure of the surgical site

To avoid including at least one tooth on either side of the intended tooth

To maintain an adequate blood supply to the reflected tissue (correct)

Why should incisions over bony defects be avoided during flap design?

They may result in flap ischemia

They may cause postsurgical soft tissue fenestrations or nonunion of the incision (correct)

They may compromise visibility

They may cause delayed healing
