CIT Treatment Protocols & Procedures 3

Question 1

Which protocol defines placing a restoration in occlusion within 48 hours of implant surgery?

Accepted Answer

Immediate loading

Answer

Immediate loading places a restoration in occlusion within 48 hours of implant placement, requiring high primary stability.

Question 2

A patient requires bilateral sinus augmentation. Which approach is preferred when residual bone height is less than 4 mm?

Accepted Answer

Lateral window sinus augmentation

Answer

The lateral window approach is indicated when residual bone height is insufficient (<4–5 mm) for the crestal technique.

Question 3

During a ridge split procedure, the primary instrument used to expand the thin alveolar ridge is:

Accepted Answer

Piezoelectric osteotome or manual spreader osteotomes

Answer

Piezoelectric tips or manual osteotomes are used to split and laterally expand the buccal and lingual cortical plates of a thin ridge.

Question 4

The 'platform switching' concept in implant prosthetics primarily serves to:

Accepted Answer

Shift the abutment-implant junction inward to preserve crestal bone

Answer

Platform switching uses a smaller-diameter abutment on a wider implant platform to move the microgap inward and reduce crestal bone resorption.

Question 5

A Schneiderian membrane perforation during lateral sinus augmentation that is small (<5 mm) is best managed by:

Accepted Answer

Placing a resorbable collagen membrane patch over the tear and continuing

Answer

Small perforations can be managed by folding the membrane on itself or placing a resorbable collagen membrane patch before grafting.
