What is the primary purpose of the immediate denture tooth try-in?

The primary purpose of the immediate denture tooth try-in is to confirm the vertical dimension of occlusion (VDO). During this stage of denture fabrication, it is essential to ensure that the occlusal relationship of the denture teeth is appropriate to maintain proper jaw relationships, functionality, and aesthetics.

Achieving the correct VDO is critical because it affects the patient's facial appearance, the effectiveness of chewing, and overall comfort. If the VDO is not maintained correctly, it can lead to complications such as temporomandibular joint disorders or an improper bite, which may result in further adjustments or discomfort once the dentures are finalized.

While the other options are important components of the try-in process, such as fit, comfort, aesthetics, and functionality, confirming the VDO is paramount, as it serves as the foundational aspect of proper denture function and overall patient satisfaction.
