How can the retention of an RPD be maximized during design?

Maximizing the retention of a removable partial denture (RPD) during its design is fundamentally linked to the optimization of the contours of the remaining teeth. The contours of the teeth play a crucial role in providing multiple retentive features for the clasps and other components of the denture. When the contours of the teeth are favorable, they can enhance the grip of the retention elements on the natural tooth structure, thus increasing the overall stability and retention of the RPD in the oral cavity.

Properly shaped teeth allow for better engagement of the clasps, which can be designed to take advantage of undercuts and other anatomical features. This engagement can create a secure fit that helps to keep the denture in place during function, such as chewing and speaking. Furthermore, optimizing the contours can also help in distributing functional loads more evenly, contributing to the longevity and comfort of the denture.

In contrast, minimizing the surface area of the denture compromises retention, as it reduces the area of contact with the supporting oral tissues. Using multiple types of clasps might provide additional retention options, but it doesn’t directly address the fundamental aspect of optimizing tooth contours. Lastly, increasing the weight of the framework could negatively impact comfort and may not significantly contribute to
