Questions and Answers

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
