What is an occlusal X ray?
What is an occlusal X ray?
Occlusal. These X-rays show the roof or floor of the mouth. They are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft in the roof of the mouth (cleft palate), cysts, abscesses, or growths.
How is occlusal X ray taken?
Occlusal radiography is defined as those intraoral radiographic techniques taken using a dental X-ray set where the image receptor (film packet or digital phosphor plate – 5.7 × 7.6 cm) is placed in the occlusal plane. Suitable sized solid-state digital sensors are not currently available.
What is the purpose of the maxillary topographic occlusal projection?
Topographic projection: The maxillary topographic occlusal projection is used to examine the palate and the anterior teeth of the maxilla.
What is the primary purpose of an occlusal radiograph?
Periapical/occlusal radiographs are indicated for identifying or confirming pathology, evaluating dental development, dento-alveolar trauma, deep carious lesions, periapical pathology, and oral involvement of systemic disease.
What is the occlusal technique?
What is the occlusal technique used for? to examine large areas of the upper or lower jaw. The chewing surfaces of the posterior teeth. occlusal surfaces. A type of intraoral radiographic examination used to inspect large areas of the maxillary or mandible on one film.
What is periapical film?
A periapical x-ray or “PA film” will show one or two teeth in their entirety in one single image, right from the crown of the tooth which is the part exposed in the mouth to the very tips of the tooth roots located in the jawbone, as well as the surrounding bone supporting this tooth.
What is an occlusal image?
Occlusal X-rays show the roof or floor of the mouth and are used to find extra teeth, teeth that have not yet broken through the gums, jaw fractures, a cleft palate, cysts, abscesses or growths.
What is the orientation of maxillary standard occlusal radiograph?
The maxillary standard occlusal radiograph is made with a size 4film/phosphor plate. The film/phosphor plate is positioned with its long axis laterally. The central ray (PID) is aimed with a vertical angle of +65 to +70 degrees, a horizontal angle of 0 degrees andcentered on the bridge of the nose.
What is a true occlusal radiograph?
PID positioned (centered on chin) with a vertical angle of – 55 to -65 degrees and a horizontal angle of 0 degrees. Example adult mandibular anterior occlusal radiograph. Example child mandibular anterior occlusal radiograph. The mandibular true occlusal radiograph is one of the most commonly made occlusal radiographs.
What is a mandibular topographical occlusal used for?
Mandibular Topographical Occlusal Uses: To view the anterior portion of the mandible for fractures, cysts, root tip and periapical pathology. It provides a very good view of the symphysis region of the mandible. (Figure 65)
What is a posterior oblique maxillary occlusal projection?
Posterior Oblique Maxillary Occlusal Uses: To view the maxillary posterior region and provide a topographical view of the maxillary sinus. The projection may be used in place of periapical films in patients who have a tendency to gag and for examining periapical pathology and root tips. (Figure 71)
