What offers resistance to horizontal dislodging forces in dentures?

  1. Retention

  2. Stability

  3. Support

  4. Buccal shelf

The correct answer is: Stability

Stability is the correct answer because it offers resistance to horizontal dislodging forces in dentures. Retention, on the other hand, refers to the ability of the dentures to resist vertical dislodging forces. Support is the term used for the ability of dentures to resist vertical pressure and maintain proper occlusion. The buccal shelf is a bony prominence on the lower jaw that can provide additional support and stability for the dentures, but it is not the primary component responsible for resistance to horizontal dislodging forces. Therefore, stability is the most fitting option for this question.
