What is the significance of retromolar pad?
Different shapes of retromolar pad helps in stability of lower denture by providing surface area, larger diameter contributes to broader surface area and better distribution of functional forces per unit area and plays a significant role in stability of lower denture [13].
What attaches to the retromolar pad?
The retromolar pad contains an extension of the palatine salivary glands and lies over the retromolar triangle of the mandible, overlapping the attachments of the pterygomandibular raphe, the buccinator and superior constrictor muscles, and the lingual tuberosity.
What is the retromolar triangle?
The retromolar triangle, retromolar fossa, retromolar space or retromolar gap is a space at the rear of a mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin. The pterygomandibular raphe connects the hamulus of the medial pterygoid plate to it.

- Platysma – inserts on the inferior border of the mandible.
- Superficial masseter – inserts on the lateral surface of the ramus and angle of the mandible.
- Deep masseter – inserts on the lateral surface of the ramus and angle of the mandible.
