Receptor is positioned as close as possible to the lingual surface of the teeth, resting in the . Parallel angle technique vs bisecting angle technique. Peri-apical radiograph: Intraoral techniques designed to . When comparing the two techniques, the advantages of the paralleling technique are: . Better dimensional accuracy: the paralleling technique in less .

Whencomparing the two techniques, the advantages of theparalleling technique are: 1.

Maxillaryview Bisecting angle technique -the bisector of the angle formed by the film and the long axes of the teeth is first determined and then the central ray is directed perpendicular to the bisector.

The X-ray tubehead is then aimed at right angles (vertically and horizontally) to both . This technique is used in areas where the parallel technique is impossible due to poor access, making the angle between tooth and film more than degrees. Technique errors vertical alignment error . Using this technique , a true image of the tooth length and width is obtained. Check out the catootheus dental T-shirt! Available in multiple colors and sizes.

Demonstration on how to take dental x-rays with the bisecting angle technique. Instructions are given for making the complete periapical examination of the adult dentition with the film positioned at an angle to the long axes of the tee. The films are wrapped in packets of white, pebble moisture-resistant paper or. The following discussion provides detailed information on how to take periapical and interproximal (bitewing) radiographs, using both techniques. For the occlusal examination, you will use only the bisecting angle technique.

Full Mouth SeriesThe paralleling and bisecting angle techniques are used totake periapical films and have nothing to do with thebitewing technique. In general, the film can be placed closer to theteeth using the bisecting angle technique (with fingerretention) than with the paralleling technique. However, there will be more distortion of the image with thebisecting technique.

The theoretical basis of the bisected angle technique is shown in the following Figure and can be summarized as follows: 1. The film packet is placed as close to the tooth under investigation as possible without bending the packet. The angle formed between the long axis of the tooth and the long axis of the film packet is . How to tell the difference between the bisecting angle technique and paralleling technique. Made by MrCDA2for dental-imaging.

This technique requires the use of intraoral film, which is placed inside the mouth and is used to examine the teeth and supporting structures.
