Extended occlusal rests are particularly utilized when there is a need to provide added support and stability to a dental prosthesis, especially in complex situations. In scenarios where the most posterior molar abutment is mesially tipped, particularly in Class II (Modification I) or Class III situations, the use of extended occlusal rests helps to distribute occlusal forces more effectively. This adaptation is crucial because the altered alignment of the molar can lead to uneven stress distribution, thereby increasing the risk of failure of the prosthetic appliance.

By using extended occlusal rests in these cases, the dentist can create a more favorable condition for the prosthetic framework by improving its retention and support. This method compensates for the changes in the occlusal plane caused by the mesial tipping of the abutment tooth, ultimately aiding in the long-term functionality and stability of the dental restoration. In this way, the use of extended occlusal rests is a strategic decision to enhance treatment outcomes in situations where molar positioning complicates the prosthetic design.
