The two major portions of the rodent mandible are the corpus, or body, primarily composed of the molar and incisive alveolar regions supporting tooth roots, and the ascending ramus, composed of three muscular processes, the
coronoid, the condyloid, and the angular, along with the central masseteric region.
Skin electrodes are placed on the face over the
coronoid notch of the mandible, and they send impulses over the nerves beneath it.
A laterally-flaring angular processes, a low
coronoid process, a vertically oriented temporal fossa, and a high origin/insertion ratio of the temporal muscle suggest wide gapes and strong bites in carnivorous mammals (Emerson & Radinsky, 1980; Freeman, 1988).
The ramus curves laterally in the dorsal part and is accentuated by the
coronoid process.
B--Temporal tendon--anterior edge of
coronoid process.
A possible explanation for recurrence in the second case would be retained periosteum over the
coronoid process.
The allogeneic fascia lata was interposed like a waterfall from the olecranon over the
coronoid process up to the posterior side of the humeral articular surface.
The zygomatic arch is the insertion site for the masseter muscle and protects the temporalis muscle and the
coronoid process.2,3
Mandibular fracture occurs in common location like body (29%), condyle (26%), angle (25%), symphysis (17%), ramus (4%) and
coronoid process.
In total, 15 cranial measurements were taken with a digital caliper with the greatest possible accuracy (0.01 mm), including: greatest length of skull (GLS), condylobasal length (CBL), basal length (BL), occipitonasal length (ONL), palatal length (PL), length of palatal bridge (PBL), length of incisive formina (LIF), breadth of incisive formina (BIF), length of upper tooth row (LUTR), length of upper molars (LUM), maximum upper molars breadth (GUMB), heigth of
coronoid process of mandible (HCPM), length of lower molar row (LLMR), lower tooth row (LTR), mandibular height (MH) (Fig.
Intraoral incision must be made in the mucobuccal sulcus in the superior posterior direction between the
coronoid process and maxillary third molars (15, 16).
