the inferior border of the mandible (lingual surface) inferiorly; the medial pterygoid muscle medially (the space is superficial to medial pterygoid) the ascending ramus of the mandible laterally (the space is deep to the ramus of the mandible)
The forensic term for the midpoint of the mandibular angle is the gonion. The gonion is a cephalometric landmark located at the lowest, posterior, and lateral point on the angle. [1] This site is at the apex of the maximum curvature of the mandible, where the ascending ramus becomes the body of the mandible.
The retromolar space or retromolar gap is a space at the rear of the mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin. This gap is generally small or absent in modern humans, but it was more often present in Neanderthals , [ 1 ] and it was common among some ...
The mandible has two main holes , found on both its left and right sides: The mandibular foramen, is above the mandibular angle in the middle of each ramus. The mental foramen sits on either side of the mental protuberance (chin) on the body of mandible, usually inferior to the apices of the mandibular first and second premolars. As mandibular ...
Montmaurin-La Niche includes an intact mandibular body and six teeth, only missing the upper alveolar wall and a portion of the internal right corpus wall aside from the missing teeth. One edge of the right ascending ramus, left coronoid, and both sigmoid notches are damaged and the body has a few cracks.
The mandible of Periptychus was particularly robust; the paired dental bones were co-ossified toward the end, and went to form a high mandibular symphysis that extended from the incisors to the ventral limit of the mandible, at the level of the anterior margin of the second inferior premolar. The ascending ramus of the mandible was rather high ...
The cut is then made inferiorly on the ascending ramus to the descending ramus, extending to the lateral border of the mandible in the area between the first and second molar. At this time, a vertical cut is made extending inferior to the body of the mandible, to the inferior border of the mandible.
The Curve of Spee is distinct from the Curve of Wilson, which is the upward (U-shaped) curvature of the maxillary and mandibular occlusal planes in the coronal plane. The Curve of Spee is basically a part of a circle (8-inch diameter) which has its circumference as the anterior ramus of mandible.
