Sample item

Which material is typically used for dental implant fixtures because it osseointegrates?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Titanium

Commercially pure titanium or its alloys form a stable oxide layer and bond directly to bone (osseointegration, described by Branemark). Implants replace missing tooth roots.

Option by option

  • A. Titanium (correct)

    Correct. Titanium osseointegrates.

  • B. Acrylic resin

    Acrylic is not strong enough for fixtures.

  • C. Gutta-percha

    Gutta-percha is a soft root filling material.

  • D. Silver amalgam

    Amalgam would corrode and does not integrate.
