Question 2

What is the primary purpose of an emergence profile in implant prosthetics?

Accepted Answer

To shape the peri-implant soft tissue contour

Question 3

Which impression technique captures the position of the implant in the arch for prosthetic fabrication?

Accepted Answer

An open-tray implant-level impression uses impression copings and allows the tray to remain open so copings are retrieved with the impression.

Question 4

What material is commonly used for CAD/CAM-milled implant abutments due to its strength and biocompatibility?

Accepted Answer

Zirconia

Answer

Zirconia is widely used for CAD/CAM abutments because it combines excellent biocompatibility with high flexural strength and esthetic tooth-colored appearance.
