Finishing and Polishing Restorations · CDA

For ceramic or porcelain restorations, why might special polishing systems be needed compared to composite resin restorations?

  1. Because ceramic is softer than composite and therefore polishes far too easily
  2. Because ceramic needs diamond or specialized abrasives for a smooth finish
  3. Because ceramic restorations do not require any polishing at all
  4. Because ceramic surfaces are always perfectly smooth right after firing
Show answer and explanation

Correct answer: Because ceramic needs diamond or specialized abrasives for a smooth finish

Ceramic restorations are harder and require special abrasive polishing systems (e.g., diamond-impregnated tools) to produce smooth, enamel-like surfaces and resist staining and plaque.
