Read the first 6 Complications & Maintenance flashcards as text

  1. The recommended maintenance recall interval for implant patients after the first year of loading is typically:

    Answer: Every 3–6 months depending on risk factors

    Implant maintenance every 3–6 months allows early detection of peri-implant disease, mechanical complications, and ensures continued patient hygiene compliance.

  2. Which instrument is safest to use for calculus removal around titanium implants to avoid scratching the surface?

    Answer: Plastic, carbon fiber, or titanium-specific curettes

    Non-metallic or implant-specific instruments prevent scratching the titanium surface, which creates rough areas that increase bacterial adhesion and accelerate peri-implantitis.

  3. Implant fracture is most commonly associated with:

    Answer: Small diameter implants under excessive occlusal load or in bruxers

    Narrow diameter implants subjected to heavy parafunctional forces or occlusal overload are at highest risk of fatigue fracture through the implant body.

  4. Retrograde peri-implantitis (implant periapical lesion) occurs when:

    Answer: Infection from the surgical site or residual pathology affects the periapical region of the implant

    Retrograde peri-implantitis presents as a periapical lesion around an otherwise well-integrated implant, often from residual infection, overheated bone, or contamination during surgery.

  5. When peri-implantitis has caused significant bone loss, which treatment approach aims to regenerate lost bone?

    Answer: Surgical debridement with guided bone regeneration (resective or regenerative surgery)

    Surgical access allows thorough decontamination of the implant surface followed by bone grafting and GBR to attempt to regenerate the lost supporting bone.

  6. Which radiographic finding specifically indicates active peri-implantitis progression rather than stable remodeling?

    Answer: Serial radiographic comparison showing progressive crestal bone loss over time

    Progressive bone loss detected by comparing sequential radiographs is the hallmark of active peri-implantitis rather than the initial 1–2 mm remodeling expected after placement.
