What is the reason for a try-in for an immediate denture?

The try-in for an immediate denture serves multiple purposes, one of which is to check the vertical dimension. This is a crucial step because the vertical dimension refers to the distance between two points, such as the upper and lower jaws, when the teeth are in occlusion. Ensuring the correct vertical dimension is vital for the overall comfort and function of the denture, as it affects how the denture will fit and perform once placed in the patient’s mouth.

Maintaining an appropriate vertical dimension helps in preventing issues related to occlusion, such as soreness of the alveolar ridge, muscle strain, or misalignment of the jaw. An incorrect vertical dimension can lead to an improper bite and discomfort for the patient, so it is essential to assess this during the try-in phase.

While verifying aesthetics, checking phonetics, and observing excursive movements are also important steps in the denture fitting process, the verification of the vertical dimension has a foundational role in ensuring that the prosthesis will meet basic functional requirements before considering these additional aspects.
