Exam 11: Accessory Radiographic Techniques: Bisecting Technique and Occlusal Projections

The topographic occlusal projection can be used for:

A -5 degree vertical angulation for the lower incisors will produce a (an)________ image.

Occlusal films can be processed in the darkroom, with similar technique to standard intraoral films. The exposure times of occlusal films is usually greater than intraoral periapical films.

Identify a possible patient scenario in which the bisecting angle technique would be used:

When compared with periapical films, topographic occlusal films have a __________.

Compared with standard intraoral films, the occlusal film size is approximately:

A +75 degree vertical angulation for a maxillary cuspid will produce a (an)________ image.

If the vertical angulation of the PID is insufficient, _______ will result.

In the bisecting technique the tooth-film distance is:

The imaginary angle that is bisected with the use of the Bisecting Angle Technique is formed between the long axis of the tooth and:

____________________ exposure times can be used for the bisecting technique because of the shorter FFD.

Identify the major disadvantage of the bisecting technique:

Identify the number that correlates to the size of an occlusal film packet:

The finger holding method should _____ be used with the bisecting technique.
