Question 1

Which technique is used to evaluate the volumetric stability of soft tissue grafts used for peri-implant tissue augmentation?

Accepted Answer

Superimposition of intraoral scans at baseline and follow-up

Answer

Superimposing serial intraoral scans allows three-dimensional volumetric assessment of soft tissue graft changes over time.

Question 2

Screw-retained implant restorations are preferred over cement-retained restorations primarily because they:

Accepted Answer

Eliminate the risk of residual cement causing peri-implant disease

Answer

Screw-retained restorations eliminate subgingival cement, a major risk factor for peri-implantitis, and allow retrievability for maintenance.

Question 3

The Summers osteotome sinus floor elevation technique relies on which principle to elevate the sinus membrane?

Accepted Answer

Controlled infracture of the sinus floor bone using blunt instruments

Answer

The Summers technique uses sequentially larger osteotomes to condense and infracture the sinus floor, elevating the membrane via the crestal approach.

Question 4

A patient presents with implant mobility 18 months after placement. The most appropriate initial management is:

Accepted Answer

Remove the implant immediately

Answer

Mobility indicates complete failure of osseointegration; a mobile implant cannot be stabilized through conservative measures and must be removed.

Question 5

According to the 2017 World Workshop classification, peri-implant mucositis is characterized by:

Accepted Answer

Bleeding on probing without radiographic bone loss

Answer

Peri-implant mucositis is defined by bleeding on probing (and/or suppuration) with increased probing depths compared to baseline, but without radiographic bone loss.
