intra oral radiogrpahic anatomy e lec pictures Flashcards
what is this image pointing to
the inter maxillary suture
what is this pointing to
the anterior nasal spine
radioopaque V shaped line which lies above the anterior apices
what is the issue with this image
that the soft tissues have super imposed on the ant superior bone portion of the radiograph
what si the nasal end of the incisive foramina seen as on a radiograph
two ovoid structures that lie either side of the anterior nasal spine
what is the nasal end of the incisive foramina seen as on a radiograph
it is seen as a concavity radioluscent structure that lies above the nasal septum
what can be the issue with the oral end of the incisive canal on a radioluscency
it can be projected over the apex of the central incisors and can resemble an inflammatory cyst but usually this is much bigger
what are the anterior parts of the nasal cavity known as
the pyriform fossa
what is this thick band of radioopacity seen
the interior nasal conchae
what can be the issue with the canine fossa
as there is less bone as we move posteriorly- and therfore less tissue we can see a radiolucency
what is this image pointing at
poorly defined canine fossA
what can be the issue with the antrum
it can be mistaken as a radiolucency of the maxillary antrum
what is the maxillary antrum
the maxillary sinus
what is the Y shape of ennis
it is an upside down Y where the medial side of the Y is the body of the antrum as well as one side fo the Y being the floor of the antrum and the other side being the floor of the nose
what is the floor of the nose seen like
a radioopaque flat horizontal line on an occlusal or post PA
WHAT is the zygomatic buttress
it is an radiodensity due to the zygoma meeting the maxilla
what is the structure outlined
the hamulus- a part of the medial pterygoid plate
what lies anterior to the hamulus
is the hamular notch
why is the hamular notch important
as when making dentures we should extend the denture in this area as the soft tissue can give
what is the maxilla tuberosity
it is the area of the maxilla posterior the last molar and associated with the third molar
what is highlighted
the coronoid process
which structure is circled
the deal duct or the nasal lacrimal duct
what structure is highlighted
the neuro vascular channals
what is this structure
the mental foramen- seen where the IAN enters and divides into the incisive nerve to supply the lower anterior teeth
what is shown on this PA of the LL quadrent
the mylohyoid ridge
what is shown beneath the myloid ridge
the submandibular fossa- this holds the sub mandibular salivary gland
which structure is highlighted
the Inferior alveolar nerve
what structure is this
the large radioopaque structure seen anterior to the central incisors in the mental protuberance
what is shown on this image
the naso lacrimal ducts
what is shown on this image
the inter maxillary suture
what is shown on this image
hamular notch
what is shown on this image
the pyriform fossa
what is shown on this image
the lamina dura in which the PDL inserts into
what is shown on this image
the oral end of the incisive foramen
what is shown on this image
neurovascular channel
what is structure A
what is structure B
structure A is the inflammatory cyst
structure B is the incisive foramen
what is shown on this image
the external oblique ridge- shows how difficult wisdom tooth removal is
what is shown on this image
incisive foramen
what is shown on this image
floor of the antrum
what is shown on this image
anterior nasal spine
