The Performance of Paralleling Technique and Bisecting Angle Technique …
There are two radiographic techniques for taking periapicals: the paralleling technique (P tech) and bisecting angle technique (B tech) (Figure 1). P tech involves placing the film receptor parallel to the long axis of the target tooth such that the central x-ray beam is directed perpendicular to both the receptor and the tooth.

Bisecting Angle Technique. The bisecting angle technique is accomplished by placing the receptor as close to the tooth as possible. The central ray of the x-ray beam should be directed perpendicular to an imaginary line that bisects or divides the angle formed by the long axis of the tooth and the plane of the image receptor (Figure 7).

Bisecting Technique. The receptor must be placed along the lingual surface of the tooth. The receptor’s plane and the tooth’s long axis form an angle at the point where the film contacts the tooth. Imaginary bisector bisects the angle formed by the receptor and the long axis of the tooth.
There are two types of techniques used for periapical radiographs: bisecting angle, and paralleling. The bisecting technique may have to be used for patients unable to accommodate the film positioning device used in the paralleling technique. These patients may include adults with low palatal vaults and children.

2015年1月8日 · The Bisecting Angle Technique. The bisecting angle technique can be used in some special circumstances, for example, in difficult or unusual anatomy, such as in patients with a very shallow palate or a very short lingual frenum, or when palatal or mandibular tori (bone growths) are present.
The bisecting angle technique is used when the sensor cannot be placed parallel to the long axis of the tooth. The sensor is positioned at an angle behind the tooth in question. An imaginary line bisects the angle formed by the long axis of the tooth and the film. The x-ray beam is aimed at a right angle to that imaginary line.

Bisecting technique is based on the principle of isometry given by Ceiszynski in 1907, which state that two triangles are always equal when they have two equal angles and a common side.
Film holders have been devised to standardize the bisecting-angle technic, thus eliminating the ne cessity for specific head position and predeter mined tube angulation. This simplified technic produces accurate duplication of radiographs and reduces technical errors.
