Which item is made so the dentist can register the patient's bite (relate the upper model to the lower model)?

• A. Bite Rims
• B. Final Model
• C. Custom Tray
• D. Impression

Answer: (A)

Registering how the jaws come together is done with bite rims. These rims, usually wax or acrylic, are placed on the upper and lower models on an articulator to simulate the patient’s bite and set the vertical dimension of occlusion and the centric relation. By having the patient bite on these rims or by using bite registration material between them, the dentist captures the exact relationship between the upper and lower arches. This bite record lets the lab mount the casts in the correct relation on the articulator and guide prosthetic fabrication. The other items serve different purposes: a final model is the completed cast after processing, a custom tray is used to hold impression material during taking impressions, and an impression is the negative imprint used to make the model. Bite rims are specifically for registering and relating the two arches.
