Question 1

What is the minimum healing time typically required for osseointegration before loading a standard implant?

Accepted Answer

8–16 weeks

Answer

Standard implant protocols typically require 8–16 weeks of unloaded healing to allow adequate bone-implant contact before functional loading.

Question 2

Implant stability quotient (ISQ) measured by resonance frequency analysis (RFA) is used to assess:

Accepted Answer

The degree of osseointegration and implant stability

Answer

RFA measures the resonance frequency of a transducer attached to the implant, generating an ISQ value (1–100) that reflects primary and secondary stability.

Question 3

Which type of bone defect is best described as a horizontal deficit where the ridge has lost width but not height?

Accepted Answer

Horizontal bone defect

Answer

A horizontal bone defect reduces ridge width, requiring lateral augmentation (e.g., GBR or block graft) to widen the ridge before or concurrent with implant placement.

Question 4

Guided bone regeneration (GBR) uses a membrane to:

Accepted Answer

Exclude epithelial and connective tissue cells from invading the graft

Answer

GBR membranes act as a barrier to prevent fast-proliferating epithelial and connective tissue cells from colonizing the space needed for bone regeneration.

Question 5

Which of the following is a sign of failed osseointegration (implant failure)?

Accepted Answer

Mobility of the implant under digital pressure

Answer

A clinically mobile implant indicates failure of osseointegration, as a successfully integrated implant should be completely rigid with no movement.
