Which of the following is NOT a reason to perform a chair-side remount for a major fixed case?

Performing a chair-side remount is pertinent in various situations, particularly when addressing specific changes that may affect occlusion and fit in prosthodontic treatments. The reason identified as the correct response revolves around the inadequacy of intraoral occlusal adjustments in large fixed cases.

Intraoral occlusal adjustments may not effectively resolve significant occlusal discrepancies or adjustments required due to alterations that have occurred during the fabrication process or due to tooth movement. These adjustments can be more complex and challenging to manage consistently in larger cases, where precision is crucial for function and aesthetics. When the occlusion is significantly off, or there are structural concerns that need to be addressed, a chair-side remount allows for a more controlled environment and accurate adjustments on a mounted cast rather than relying solely on chair-side adjustments, which may not capture the full extent of the issues at hand.

In contrast, the other reasons emphasize the importance of addressing discrepancies that can arise from previous work, the establishment of accurate occlusion that considers dimension changes during the indirect processes, and necessary adjustments due to significant tooth movements. These situations justify a chair-side remount, aiming to optimize occlusal contacts and ensure the overall success of the procedure.
