Various Radiographic Techniques used in Oral and Maxillofacial Surgery and their Uses:
Intraoral periapical View
Occlusal View
Orthopantamographs:
Lateral Oblique View
Waters view or Occipitomental View
Trans Orbital View
Trans Cranial View
Lateral Cephalogram
Postero-Anterior view of Skull
Sub-Mento Vertex View (Jug handle view)
Chest X-ray
Tomogram
Intraoral periapical View structures seen and its uses in Oral Surgery:
This Radiographic View is used whenthe following anatomic structures are to be considered fro treatment:
Third Molar
Periapical View of all the teeth in both the arches
Periapical view of maxillary sinus relation to the teeth
Fractured root apices
dentoalveolar fractures
Occlusal View structures seen and its uses in Oral Surgery:
This the radiographic technique where the view is occlusal and the structures seen are:
Mandibular floor of the mouth
Lingual aspect of the mandibular lower arch contour and continuity of the Upper Arch
Palatine Tori
Tumors of the Mandibular arch
To Locate the presence of foreign bodies in the lower arch
To confirm the presence of exact position of the foreign body weather Buccal or Lingual
RADIOGRAPHS USED FOR ORAL SURGERY

To determine bucco lingual position of impacted tooth
To determine expansion of cortical plate
Evaluation of fracture of jaws with displacement
Structures seen in Orthopantamograph and its uses in Oral Surgery:
With this radiograph you can view both the mandibular and maxillary arches which will be shown in buccal view and the following
structures can be viewed with this radiograph:
Temporo Mandibular Joint
Posterior and Anterior Border Of Ramus
Ramus of Mandible
Angle of Mandible
Body Of Mandible
Continuity of inferior border of Mandible
Pterygomandibular fissures
Maxillary Tuberosity
Maxillary Sinuses
Teeth
Will be very helpful in determining the fractures in Ramus, angle and body of mandible
Lateral Oblique View structures seen and its uses in Oral Surgery:
Mandibular Ramus Projection demonstrates mandibular Ramus from angle to condyle
Third molars of maxilla and mandible
Mandibular body projection demonstrates the premolar molar region and inferior border of mandible
Waters view or Occipitomental View structures seen and its uses in Oral Surgery:
This Radiographic view gives you a very detailed view of all the sinuses, introduced by Water hence named Waters view. The
various structures which can be viewed are:
Maxillary Sinus
Frontal Sinus
Ethmoidal Sinus
Frontozygomatic suture
Infra and supra orbital rims
Nasal Cavity

sition of coronoid process of mandible between maxilla and zygomatic arch
Trans Orbital View structures seen and its uses in Oral Surgery:
Also called as Zimmer or Transmaxillary projection which is mainly concentrating on the TMJ. The following structures are visible.
Mandibular condylar neck
Used for diagnosis of Sub-condylar fractures
Latero medial articulating surfaces of the condyle and articular eminence and condylar neck can be seen
Trans Cranial View structures seen and its uses in Oral Surgery:
The structures which can be seen to determine the treatment plan are:
Glenoid Fossa
Articular Eminence
Condylar head
The relation of Articular eminence to Condylar head
This technique is taken in 2 aspects one with clsed mouth and the other with an open mouth to determine
TMJ joint internal derangements
TMJ Dislocation and
TMJ Subluxation
Lateral Cephalogram structures seen and its uses in Oral Surgery:
It is a technique where the radiograph is taken from the side to view the following structures:
Skull
Facial Bones
Paranasal Sinus
Hard Palate
Nasopharyngeal tissue
Soft Tissue Orifices of Face
Postero-Anterior view of Mandible structures seen and its uses in Oral Surgery:
The structures seen are

Body of mandible
Inferior and Anterior vorder of Ramus
Condylar Neck
Nasal Cavity
Postero-Anterior view of Skull structures seen and its uses in Oral Surgery:
Skull
Frontal Sinus
Ethoidal Sinuses
Nasal Fossa
Orbits
Sub-Mento Vertex View (Jug handle view) structures seen and its uses in Oral Surgery:
The various structes which can be viewed to proceed with the treatment plan are:
Base of Skull
Position and orientation od condyle
Sphenoid sinus
Inferior border of mandible
Lateral wall of maxillary sinus
Zygomatic arch
Lateral pterygoid plates
Foramina at the base of skull
