Read the first 7 CIT Bone Grafting & Osseointegration flashcards as text

  1. Which growth factor found in platelet-rich plasma (PRP) is most directly responsible for stimulating osteoblast proliferation at a graft site?

    Answer: PDGF (Platelet-Derived Growth Factor)

    PDGF is the primary mitogen in PRP that directly stimulates osteoblast proliferation and recruitment to the graft site.

  2. A patient presents with a severely atrophic maxilla requiring vertical bone augmentation. Which technique is most appropriate for gaining more than 5 mm of vertical height?

    Answer: Distraction osteogenesis

    Distraction osteogenesis can achieve vertical gains exceeding 5 mm by slowly separating bone segments to stimulate new bone formation in the distraction gap.

  3. What is the primary advantage of using a cross-linked collagen membrane over a non-cross-linked one in GBR procedures?

    Answer: Prolonged resorption time allowing longer barrier function

    Cross-linking extends the collagen membrane's resorption time, maintaining the barrier function longer during the critical bone maturation phase.

  4. During sinus lift surgery, the Schneiderian membrane is perforated. Which of the following is the BEST immediate management strategy?

    Answer: Repair with a collagen membrane patch and continue the procedure if perforation is small

    Small perforations can be managed with a resorbable collagen membrane patch that acts as a scaffold, allowing the procedure to continue safely.

  5. In the context of implant osseointegration, what does the Implant Stability Quotient (ISQ) measure?

    Answer: Resonance frequency of the implant-bone interface via an electromagnetic transducer

    ISQ uses resonance frequency analysis (RFA) to quantify implant stability non-invasively on a scale of 1–100.

  6. Which of the following systemic medications is most likely to impair osseointegration by reducing osteoclast-mediated bone remodeling?

    Answer: Bisphosphonates

    Bisphosphonates suppress osteoclast activity, which can impair the normal bone remodeling essential for osseointegration and carries a risk of MRONJ.

  7. A block graft harvested from the mandibular ramus is classified as which type of bone graft?

    Answer: Autograft

    An autograft is bone harvested from the patient's own body, making ramus block grafts the gold standard for osteogenic potential.
