Dental Implants Surgical Procedures & Techniques

Question 1

In a two-stage implant protocol, the second-stage surgery involves:

Accepted Answer

Removing the cover screw and placing a healing abutment

Answer

Second-stage surgery re-exposes the buried implant, removes the cover screw, and places a healing abutment to prepare the soft tissue for restoration.

Question 2

What is the primary purpose of sequential drilling (drill protocol) during implant osteotomy preparation?

Accepted Answer

To incrementally enlarge the osteotomy while minimizing heat generation

Answer

Sequential drilling gradually widens the site to the final diameter while controlling bone temperature and preventing thermal necrosis.

Question 3

Bone temperature should not exceed which threshold during implant drilling to prevent thermal osteonecrosis?

Accepted Answer

47°C

Answer

Sustained bone temperatures above 47°C for more than 1 minute cause osteonecrosis, which can prevent osseointegration and lead to implant failure.

Question 4

Which flap design in implant surgery minimizes damage to the blood supply and preserves interdental papillae?

Accepted Answer

Papilla-sparing (papilla preservation) incision

Answer

Papilla-sparing incision designs avoid cutting through the papillae, preserving their blood supply and reducing esthetic complications.

Question 5

Flapless implant surgery (keyhole surgery) requires which prerequisite?

Accepted Answer

Adequate bone volume confirmed by CBCT and use of a surgical guide

Answer

Flapless surgery relies entirely on CBCT data and a surgical guide for accurate placement since the operator cannot visualize the bone directly.
