California Registered Dental Assistant (RDA) Written Practice Exam

Question: 1 / 400

Where is the mixed acrylic resin placed prior to placing on the prepared tooth?

Directly on the tooth

In the impression or in the thermoplastic tray

The mixed acrylic resin is placed in the impression or in the thermoplastic tray because it allows for accurate and controlled placement of the resin on the prepared tooth. Placing the resin directly on the tooth may result in uneven coverage or excess material. Placing it on a cotton pad is not recommended as it may cause contamination or create a messy application. Using a mixing bowl is also not recommended as it can be difficult to control the amount of resin used and can result in wastage.
