When taking a final impression for a denture, what is the ideal force to apply on the tissue?

When taking a final impression for a denture, applying minimal force on the tissue is essential for several reasons. Firstly, the tissues in the mouth can be highly sensitive, and excessive force can cause discomfort or damage to the soft tissue structures. Minimal force allows for a more accurate representation of the oral contours and prevents distortion of the impression material.

Moreover, using minimal force helps to capture the natural position of the oral tissues, which is crucial for creating a well-fitting denture. If too much pressure is applied, the impression may not accurately reflect the functional movements of the patient, leading to an improper fit and potential problems such as discomfort or loss of retention.

This approach also accommodates the polymerization or setting characteristics of the impression material, ensuring that the final impression remains as faithful to the oral anatomy as possible without deformation. Therefore, applying minimal force is vital for achieving an optimal fit and function in the final denture.
