Chapter 19 Bite wing technique

Bite wing

Used to examine the interproximal surfaces of the teeth

Bite wing imagine

Includes the crowns of maxillary and mandibular teeth, interproximal areas, and areas of the crestal bone on the same image.

What do bite wings primarily detect?

Caries (cavities)

Another name for the bite wing technique

Interproximal technique

Interproximal

Between two adjacent surfaces

Interproximal examination

Intraoral examination used to inspect the crowns of both maxillary and mandibular teeth on a single image

Bite wing receptor

Type of receptor used in interproximal examination. The bite wing receptor has a "wing" or tab and the patient bites on the wing to stabilize the receptor

Alveolar bone

Bone that supports and encases the roots of teeth

Crestal bone

Coronal portion of the alveolar bone found between teeth; also known as the Alveolar crest

Contact areas

The area of the tooth that touches an adjacent tooth; the area where adjacent tooth surfaces contact each other

Horizontal bite wing

The bite wing receptor placed in the mouth with the long portion of the receptor in a horizontal direction

Opened contact

On a dental image, opened contacts appear as thin radiolucent lines between adjacent tooth surfaces

Overlapped contacts

On a dental image, the area where the contact area of one of the tooth is superimposed over the contact area of the adjacent tooth is referred to as overlapped contacts

Vertical bite-wing

The bite wing receptor is placed with the long portion of the receptor in a vertical direction

Beam alignment device

Is a device used to position an intraoral receptor in the mouth and maintain the receptor in position during the imaging procedure

Bite wing tab

May be used to stabilize the receptor during exposure. It is attached to a periaprical film

Angulation

Is a term used to describe the alignment of the central ray of the xray beam in both horizontal and vertical planes

Vertical angulation

Refers to the positioning of the PID in a vertical, or up-and-down plane.

Positive

If the PID is positioned above the occlusal plane and the central ray is directed downward

Negative

If the PID is positioned below the occlusal plane and the central is directed upward

Exposure sequence

Definite order for the receptor placements

Receptor placement

The specific area where the receptor must be positioned before exposure, is directed by the teeth and surrounding structures that must be included on the resulting bite wing image

Endentulous space

Is an area where teeth are no longer present

Torus

Bony growth in the oral cavity

Mandibular tori

Boney growths along the lingual aspect

Size 0

Used to examine the posterior teeth in small children

Size 2

Examine the posterior teeth in older children and adults

Size 3

Shows all the posterior teeth on one side of the arch in one radiograph

Size 4

Occlusal film is used to show large areas of the maxilla or mandible
