CIT Implant Materials & Techniques 3

Question 1

Socket shield technique involves retaining which portion of a tooth root during immediate implant placement?

Accepted Answer

The buccal root fragment

Answer

The socket shield technique retains the buccal root fragment to preserve the bundle bone and buccal plate, preventing labial contour collapse.

Question 2

Platform switching in implant prosthetics refers to:

Accepted Answer

Using a narrower-diameter abutment than the implant platform

Answer

Platform switching uses an abutment with a smaller diameter than the implant platform, shifting the microgap inward and preserving crestal bone.

Question 3

Which cement property is most critical when selecting cement for cement-retained implant crowns?

Accepted Answer

Retrievability and low film thickness

Answer

Retrievability is essential to manage biological complications, and low film thickness prevents excess cement from extruding into the peri-implant sulcus.

Question 4

The Morse taper (cone-in-cone) implant-abutment connection achieves its seal primarily through:

Accepted Answer

Friction locking via cold welding

Answer

The Morse taper connection uses friction locking (cold welding effect) at the conical interface, creating a bacterial-tight seal without relying solely on the screw.

Question 5

Zirconia implants are contraindicated in patients with:

Accepted Answer

Parafunctional habits such as bruxism

Answer

Zirconia's lower fracture toughness compared to titanium makes it more susceptible to fracture under the high occlusal forces associated with bruxism.
