Which instrument should be used for routine maintenance debridement around titanium implant abutments?

  1. An ultrasonic scaler with a standard metal tip
  2. A stainless steel Gracey curette
  3. A plastic, resin or titanium curette
  4. A diamond-coated hand instrument
Show answer and explanation

Correct answer: C. A plastic, resin or titanium curette

  • A. A standard metal ultrasonic tip will damage the titanium surface.
  • B. Stainless steel scratches and gouges the titanium surface, creating micro-roughness that accelerates plaque retention and may deposit metal ions.
  • C. Correct. PLASTIC, RESIN, CARBON FIBRE or pure TITANIUM instruments are used because they are equal to or softer than the implant surface and will not scratch it. Surface scratches are not merely cosmetic — increased roughness measurably accelerates biofilm accumulation and peri-implant mucositis. If ultrasonics are used, a plastic-sheathed tip is required.
  • D. A diamond-coated instrument is highly abrasive and would severely damage the implant surface.
