What is a primary reason for conducting a try-in session for an immediate denture?

In the context of an immediate denture, conducting a try-in session primarily serves to check the vertical dimension. This is crucial because the vertical dimension significantly affects the overall function and aesthetics of the denture. If the vertical dimension is incorrect, it can lead to various issues, such as inadequate occlusion, difficulty in chewing, and compromised facial aesthetics.

During a try-in session, the clinician can evaluate how the immediate denture aligns with the patient's natural occlusal relationship and ensure that it provides enough support for the lips and mouth. Adjusting the vertical dimension at this stage can help optimize the fit and functionality of the denture once it is set.

Other aspects, such as aesthetics, fit, and shade selection, are also important in the fitting process, but the primary focus of the try-in is often on verifying the vertical dimension to ensure proper alignment and balance of the bite. This sets the foundation for a comfortable and functional denture experience for the patient.
