Dental Implants Complications & Maintenance 2

Question 1

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

Accepted Answer

Every 3–6 months depending on risk factors

Answer

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

Question 2

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

Accepted Answer

Plastic, carbon fiber, or titanium-specific curettes

Answer

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

Question 3

Implant fracture is most commonly associated with:

Accepted Answer

Small diameter implants under excessive occlusal load or in bruxers

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

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

Answer

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