When taking a final impression for dentures, how much force should be applied to cover the tissue?

In the context of taking a final impression for dentures, applying little force is preferred to ensure an accurate and comfortable reproduction of the oral tissues. When minimal pressure is used, it allows for a more precise capture of the soft tissue contours without distortion. This is essential for achieving a well-fitting prosthesis, which is critical for the health and comfort of the patient.

When too much force is applied, it may cause compression of the tissues, leading to inaccuracies in the impression and potentially resulting in ill-fitting dentures. This can compromise the denture's stability, function, and patient comfort. Additionally, an improper impression can lead to an increased risk of irritation or injury to the mucosa.

Taking little force allows the impression material to flow adequately into crevices and capture details effectively, which is vital for a successful prosthetic outcome. Hence, using little force is not only a best practice for achieving an accurate impression but also plays a crucial role in the overall success of denture fabrication.
