When harmonizing occlusion, to what thickness should the rests on RPD be adjusted?

• A. 0.5mm
• B. 1mm
• C. 1.5mm
• D. 2mm

Answer: (B)

The adjustment of the rests on a removable partial denture (RPD) to a thickness of 1mm is ideal for harmonizing occlusion. This measurement provides a balance between support and function, ensuring that the rests effectively transmit occlusal forces to the remaining teeth while maintaining proper vertical dimension. At 1mm, the rests are thick enough to distribute loads evenly across the abutment teeth, contributing to their stability and preventing potential damage or discomfort caused by excessive force. Additionally, this thickness allows for adequate clearance when closing the denture, preventing interferences during occlusion. Choosing a thickness that is too thin may not provide sufficient support or stability, potentially compromising the RPD's effectiveness. Conversely, a thicker rest could lead to occlusal discrepancies and discomfort for the patient. Therefore, 1mm is recognized as an optimal thickness for the function and comfort of the RPD.
