Mandibular Anatomy Flashcards
In infants it is a radiolucent line through the midline of the jaw between the images of the forming deciduous central incisors
Symphysis
These are bony protuberances located on the lingual surface of the mandible slightly above the inferior border and in the midline
Genial Tubercle
____ is a foramen of the lingual surface of the midline of the mandible in the region of the genial tubercles; often 2 or more
Lingual foramen
What artery runs through the lingual foramen?
Sublingual artery
Does the lingual foramen run all the way through the mandible?
NO
On periapical radiographs of the mandibular centrals, the _____ may occasionally be seen as 2 radiopaque lines sweeping bilaterally forward and upward toward the midline
Mental ridge
The _____ is a depression on the labial aspect of the mandible extending laterally from the midline and above the mental ridge
Mental fossa
The ____ is usually the anterior limit of the inferior dental canal (inferior alveolar nerve)
-Usually apical to the 1st or 2nd PM
Mental foramen
The mental foramen is distinguished from pathosis by what 2 things?
Intact lamina dura
Normal PDL space
The radiographic image of the ____ canal is a dark linear shadow with thin radiopaque superior and inferior borders
Mandibular canal
____ carry a neurovascular bundle and appear as radiolucent lines of fairly uniform width
Nutrient canals
_____ is a slightly irregular crest of bone on the lingual surface of the mandibular body
INternal oblique ridge
____ is a depression of the bone on the lingual surface of the mandibular body immediately below the internal oblique ridge in the molar area
Submandibular gland fossa
_____ is a continuation of the anterior border of the mandibular ramus
External oblique ridge
Occasionally, the ______ is seen on periapical projections as a characteristically dense, broad radiopaque band of bone
Inferior border of mandible
