What is made from the model to produce a better fitting tray for a more accurate impression?

• A. Custom Tray
• B. Final Model
• C. Impression
• D. Operatory Procedure

Answer: (A)

The main idea is that a custom tray is built on the model so the tray fits the patient’s arch precisely and provides a uniform space for the impression material. This tailored tray controls the thickness of the impression material, reduces distortion, and minimizes voids, all of which lead to a more accurate impression. The final model is simply the cast produced after pouring the impression, not something used to improve the tray. The impression is the material capture itself, not something created from the model to enhance the tray. An operatory procedure is unrelated to creating a tray from the model.
