What is the expected average annual crestal bone loss after the first year of implant placement?

2.0 mm or less
0.5 mm or less
0.1 mm or less (correct)
1.0 mm or less

Why is it important to avoid overheating the bone during implant site preparation?

It accelerates osseointegration
It increases bone-to-implant contact
It minimizes patient discomfort
It reduces the risk of failure (correct)

Which type of bone offers a much greater surface area for bone-to-implant contact?

Spongy bone
Dense bone
Compact bone (correct)
Cancellous bone

What is the main difference between one-stage and two-stage implant placement?

In the one-stage approach, the implant emerges through the mucoperiosteum/gingival tissue at the time of placement, while in the two-stage approach, the top of the implant and cover screw are completely covered with the flap closure. (A) Signup and view all the answers

Average crestal bone loss (1st year)

Expected bone loss around the implant after the first year of placement is 0.1mm or less.

Bone overheating during implant prep.

Avoid excessive heat during implant site preparation to reduce the risk of failure.

Bone type for implant contact

Compact bone offers a much larger surface area for bone-to-implant contact compared to cancellous bone.

Implant material requirement

Implants need to be made of sterile and biocompatible materials to ensure osseointegration (bone bonding).
