Temporary and Permanent Restorations · CDA

Which scenario most strongly indicates the need for a permanent restoration rather than a temporary one?

  1. Waiting for lab fabrication of a crown over several weeks
  2. Patient with deep cavity needing only interim protection
  3. After final tooth preparation and impressions when the permanent crown is ready
  4. After initial pulpal treatment but before final restoration
Show answer and explanation

Correct answer: After final tooth preparation and impressions when the permanent crown is ready

Once the definitive restoration (crown, inlay/onlay, etc.) is fabricated and checked for fit, a permanent restoration should be placed to provide long-term function, strength, and aesthetics. Temporary restorations are only for interim protection.
