TOPIC: PROVISIONAL RESTORATION

🎯 KEY POINTS:

🔹Indirect technique is preferred over direct technique to fabricate provisional restoration for its accuracy and protection of pulp, in case acrylic resin is used.

🔹Prefabricated polycarbonate crowns are used on prepared single anterior tooth.

🔹Bis-acryl composite resin should not be used in long-span bridges, as these are brittle in nature.

🔹The custom-made provisional restorations are made by direct or indirect technique or combination of both.

🔹Aluminium and Tin–silver crown is used in the posterior regions only.

🔹Nickel–chromium crown is rigid, more durable and has high strength.
