Which statement about the triple-tray impression technique is incorrect?

• A. Uses one tray to capture multiple impressions
• B. Used for complicated circumstances requiring single cast restoration
• C. Contralateral guidance captured without separate record
• D. Produces accurate occlusion despite interference

Answer: (C)

The triple-tray impression technique is known for efficiently capturing both occlusal and preparation impressions simultaneously within a single tray. This method allows for a less cumbersome and time-consuming process, particularly for situations involving fixed restorations like crowns or inlays. The statement that contralateral guidance is captured without a separate record reflects a misunderstanding of the technique's capabilities. While the triple-tray can capture occlusal and preparation details simultaneously, it may not adequately record complex occlusal relationships or guide the way certain occlusal contacts interact during function. In cases where specific occlusal guidance needs to be recorded—especially in patients with more complex dental anatomies or occlusal schemes—additional records could be necessary for complete diagnostic accuracy. The other statements about the triple-tray technique highlight its advantages in capturing multiple impressions and providing an effective method in simpler restorative situations. However, utilizing it as the sole method for documenting intricate occlusal relationships may not provide the necessary detail for successful treatment planning, making the chosen statement incorrect.
