Questions and Answers

Why is relief wax adapted over certain areas in maxilla during impression making?

  • To create a barrier between the tray and the tissues
  • To apply pressure on the relief areas for accurate impression
  • To prevent excessive pressure on relief areas and record tissues in anatomical rest (correct)
  • To avoid recording relief tissues in a state of anatomical rest

    • In what situations may relief be required without pressure during impression making?

  • Flabby ridge, sharp mylohyoid ridges, sharp glenoid tubercles (correct)
  • Bony spicules, healthy maxillary arch, flabby ridge
  • Healthy maxillary arch, sharp glenoid tubercles, bony spicules
  • Sharp mylohyoid ridges, areas with mucosal covering, healthy maxillary arch

    • What is the purpose of adapting relief wax over the relief area markings of the cast?

  • To create additional pressure on relief areas
  • To minimize the need for anatomical rest recording
  • To prevent excessive pressure on relief areas during impression making (correct)
  • To ensure direct contact between tray and tissues
