The retromolar space or retromolar gap is a space at the rear of the

This gap is generally small or absent in modern humans, but it was more often present in

Amerindians, such as Arikara and Mandan.[2][3]

Retromolar pad

The retromolar area of a human mandible is covered by the retromolar pad (also known as the piriformis

mucosa. It is composed of non-keratinized loose alveolar tissue covering glandular tissues and muscle fibers.[4]
It is important for supporting lower complete and partial dentures as well as landmarking in the fabrication of dentures.
