occlusal technique is a ____________ radiographic technique that is usually used in conjunction with a ______ or _______ radiographs.

which film is used to locate the following: retained roots, supernumerary, unerupted, or impacted teeth, foreign bodies in the maxilla or mandible, salivary stones in the duct of the submandibular gland, evaluate the extent of lesions in the max or man

what type of film is used to evaluate the boundaries of the max sinus or fractures in the maxilla or mandible?

which film aids in the examination of patients who cannot open their mouths more than a few millimeters?

which film can be taken to examine the area of a cleft palate and/or measure changes in the size and shape of the maxilla or mandible?

what is the first step in patient preparation before taking occlusal radiograph?

for maxillary occlusal fims, the patients head must be positioned so the maxillary is ______ with the floor and the midsagittal plane is ________ with the floor

for some mandibular occlusal films, the patients head must be ________ and positioned so the occlusal plane is _________ to the floor. For others it is _________

after placing the lead apron on your patient, what should happen last for patient preparation?

what are the three maxillary occlusal projections?

which occlusal projection is used to examine the palate and anterior teeth of the maxilla?

which occlusal projection is used to examine the palatal roots of the molar teeth (also locate foreign bodies or lesions in the posterior maxilla)

which occlusal projection is used to examine the anterior teeth of the maxilla and is recommended for use in children 5 years or younger?

what are the three mandibular occlusal projections?

which occlusal projection is used to examine the mandibular anterior teeth?

occlusal projection used to examine the buccal and lingual aspects of the mandible and locate foreign bodies or salivary stones in the region of the floor of the mouth

occlusal projection used to examine the anterior teeth of the mandible and recommended for children 5 years or younger

which 2 occlusal projections is the PID placed between the eyebrows on the bridge of the nose?

what kind of bite is used when the occlusal film is placed in the mouth?

T/F you should place the occlusal film as far posteriorly as the patient's anatomy permits.
True False

which is the only occlusal film that the central ray should be aimed 90 degrees toward the center of the film?

all but which occlusal projection is directed through the midline of the arch toward the center of the film?

in the maxillary lateral occlusal projection, once the film is placed in the mouth, should you shift the film to the right or left side of intended interest?

how far beyond the long edge of the film should be film be over the buccal surfaces of the posterior teeth?

where should the PID be placed for the maxillary lateral occlusal projection?

where should the white side of the film be facing when taking a maxillary occlusal?

in which occlusal projection will the mandible need to be perpendicular to the floor?

about where should the PID be centered in relation to the head during the mandibular cross-sectional projection?

when should the long edge of the film be in a front to back direction? (for which projection)

in what direction should the long edge of the film be placed in all projections except the maxillary lateral projection?

for which occlusal projection would the PID be CENTERED over the chin?

a method used to locate the position of a tooth or object in the jaws:

T/F a radiograph depicts the buccal-lingual relationship, or depth, of an object
True False

with the maxillary lateral projection, where is the central ray directed?

when would it be necessary to establish the buccal-lingual position of a structure?

T/F localization technique can be used to obtain three-dimensional information
True False

foreign bodies, unerupted teeth, impacted teeth, retained roots, root positions, salivary stones, jaw fractures, broken needles and instruments, and filling materials can all be seen with which technique!?

what are the two basic techniques used to localize objects?

which rule of the localization technique governs the orientation of structures portrayed in two radiographs exposed at different angles?

horizontal angulation is used when trying to locate a __________ aligned image

a vertical angulation is used when trying to locate a ___________ aligned image

which 2 angulations are used for the buccal object rule?

when comparing two radiographs after using the buccal object rule, if the object has moved in the SAME direction as the PID, that means the object is positioned ________

what is the SLOB rule?
