Maxilla (rotation) Flashcards
pterygoid plate
1) inferior part has hamular process
maxillary tuberosity
1) posterior to molar
clinical hamular notch
1) soft tissue density
zygomatic arch
1) line of contrast superior to sinus
2) the u-shaped band is the zygomatic process of the maxilla
floor of maxillary sinus
1) radiopaque line superimposed through roots of molars
coronoid process of mandible
1) only part of mandible that can be seen in maxillary radiograph
2) seen when the mouth is open wide
pneumatization of the sinus into the edentulous alveolar bone
1) sinus enlarges sometimes
vascular groove or channel
1) not a canal
2) depression on wall of the sinus
floor of the nasal fossa
1) horizontal radiopaque line located several mm above the floor of maxillary sinus
2) NOT a line of contrast
inverted Y
1) formed by floor of nasal fossa and maxillary sinus
2) only a radiographic appearance
nasolabial fold
1) can help identify right from left
2) line of contrast
anterior nasal spine
1) v shaped
floor of nasal cavity
1) extends bilaterally
incisive foramen / nasopalatine forament
1) between roots of central incisors
nasopalatine / incisive canal
1) vertical radiopaque bands above the foramen
superior foramina of nasopalatine
1) one wither side of nasal septum
nasal septum
1) thick radiopaque band
inferior concha
1) in the nasal fossa away from the septum
intermaxillary suture
1) mean suture
2) from alveolar crest through ANS, posteriorly to distal aspect of hard palate
3) uniform width, variable shape
soft tissue of the nose
1) middle third of roots of the incisors, or even beyond alveolar crest
anterior nasal spine
1) increased density at floor of nasal fossa
