Read the first 6 CIT Bone Grafting & Osseointegration flashcards as text

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

    Answer: 8–16 weeks

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

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

    Answer: The degree of osseointegration and implant stability

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

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

    Answer: Horizontal bone defect

    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.

  4. Guided bone regeneration (GBR) uses a membrane to:

    Answer: Exclude epithelial and connective tissue cells from invading the graft

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

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

    Answer: Mobility of the implant under digital pressure

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

  6. What is the primary role of platelet-rich fibrin (PRF) when used in conjunction with bone grafting?

    Answer: To release growth factors that accelerate tissue and bone healing

    PRF is a concentrated autologous blood product that releases growth factors (PDGF, TGF-β, VEGF) to promote angiogenesis and accelerate tissue regeneration.
