Using the patient's existing denture as impression tray is most likely to produce what outcome?

• A. Reduced accuracy
• B. Predictable results with expedited fabrication
• C. Higher material costs
• D. Requires new impression tray

Answer: (B)

Using the patient’s existing denture as an impression tray works because that denture already fits the arch and records the patient’s tissues and relationships. When you place impression material and seat the denture, you’re essentially reusing a form that is already known to fit the mouth, so you skip fabricating a new custom tray and you minimize trial-and-error seating. This streamlines the process, reducing chair time and steps, which leads to more predictable results since you’re relying on a tray that has already proven its fit with this patient. The main trade-off is that any changes in the tissues since the denture was made can affect accuracy, but in many cases the efficiency and consistency of using the existing denture as a tray outweigh those concerns, making it a reliable choice for expedited fabrication.
