Which statement is an exception regarding the triple-tray impression technique?

The triple-tray impression technique is designed to efficiently capture a patient's dentition in a single step, which includes both the prepared tooth as well as the opposing and adjacent teeth. By using one tray, the approach simplifies the process of making impressions, particularly useful for single-unit restorations.

The statement regarding contralateral guidance being captured without a separate interocclusal record highlights a significant advantage of this technique. This aspect is crucial for restorations as it ensures that the occlusal relationships evaluated during the impression process capture the necessary functional dynamics of the opposing dentition. The triple-tray not only gathers the impression but also incorporates the occlusal relationship, thus aligning with the purpose of streamlining the impression-taking process.

The other statements focus on the application and accuracy of the technique. While the triple-tray is ideal for uncomplicated situations, its use in more complex cases may not yield the same reliability and accuracy. Although it is effective in many situations, potential imperfections can occur, such as distortions or inaccuracies due to various technical factors. Furthermore, mentioning that it produces "extremely accurate occlusion" can be misleading, as the accuracy can be influenced by the operator's technique and the specific conditions of the patient's dentition. Therefore, the
