What is the role and dimension of stopper in complete denture?

In complete dentures, a stopper plays a crucial role in achieving proper occlusion and stability. It is typically used to maintain the vertical dimension of occlusion, ensuring that the upper and lower dentures fit together correctly during function. Additionally, stoppers help in distributing occlusal forces evenly, preventing excessive pressure on any specific area of the underlying tissues. This contributes to improved comfort and functionality for the wearer.
