Why is it crucial to ensure a proper vertical dimension during a try-in for immediate dentures?

Ensuring a proper vertical dimension during a try-in for immediate dentures is vital for several reasons, but one of the most critical aspects is to prevent jaw disorders. A correct vertical dimension helps maintain the relationship between the upper and lower jaws. When the vertical dimension is altered significantly, it can lead to an imbalance in the occlusion, causing strain on the temporomandibular joint (TMJ) and surrounding musculature. This can result in discomfort, pain, and conditions such as temporomandibular disorders (TMD).

Proper vertical dimension also plays a significant role in the overall function of the denture, affecting how well the teeth meet during chewing and speaking. While aesthetic appearance, comfortable chewing, and phonetics are important factors, preventing jaw disorders directly correlates to the functional stability and longevity of the denture, thereby ensuring the patient's well-being.
