In a two-stage implant protocol, the second-stage surgery involves:
Answer: Removing the cover screw and placing a healing abutment
Second-stage surgery re-exposes the buried implant, removes the cover screw, and places a healing abutment to prepare the soft tissue for restoration.
What is the primary purpose of sequential drilling (drill protocol) during implant osteotomy preparation?
Answer: To incrementally enlarge the osteotomy while minimizing heat generation
Sequential drilling gradually widens the site to the final diameter while controlling bone temperature and preventing thermal necrosis.
Bone temperature should not exceed which threshold during implant drilling to prevent thermal osteonecrosis?
Answer: 47°C
Sustained bone temperatures above 47°C for more than 1 minute cause osteonecrosis, which can prevent osseointegration and lead to implant failure.
Which flap design in implant surgery minimizes damage to the blood supply and preserves interdental papillae?
Answer: Papilla-sparing (papilla preservation) incision
Papilla-sparing incision designs avoid cutting through the papillae, preserving their blood supply and reducing esthetic complications.
Flapless implant surgery (keyhole surgery) requires which prerequisite?
Answer: Adequate bone volume confirmed by CBCT and use of a surgical guide
Flapless surgery relies entirely on CBCT data and a surgical guide for accurate placement since the operator cannot visualize the bone directly.
Primary stability (initial stability) during implant placement is primarily determined by:
Answer: Bone-to-implant contact achieved at time of surgery
Primary stability refers to the mechanical engagement of the implant with bone at time of placement, measured by insertion torque and resonance frequency analysis.
