    Intraoral Radiographic Techniques (The Bisecting Angle Technique)-Chapter 3 Basic Principles The bisecting-the-angle or bisecting angle technique is based on the principle of aiming the central ray of the x-ray beam at right angles to an imaginary line which bisects the angle formed by the longitudinal axis of the tooth and the plane of the. The orthopantomogram (also known as an orthopantomograph, panotomogram or an OPG) is a panoramic single image radiograph of the mandible, maxilla and teeth. It is often encountered in dental practice and occasionally in the emergency department; providing a convenient, inexpensive and rapid way to evaluate the gross anatomy of the jaws and related pathology.

A great number of experiments have been made with this technique and the results are certainly promising. In fact some kind of X-ray photogrammetry is frequently applied as a necessary prerequisite for many kinds of surgery, for instance brain surgery. The photogrammetric methods used up to now, are, however, in certain respects rather Photogrammetric principles applied to intraoral radiodontia book 4.

The basic principles of projection geometry • focal spot should be as small as possible • focal spot to object distance should be as long as possible • object to film distance should be as small as possible • long axis of object and film should be parallel • X ray beam should strike the object and film.

2. Intraoral Radiographic Principles and Techniques. Mindy Cash and Bettina Basrani. In the practice of endodontics, radiographs are diagnostic tests that provide the clinician with important information during all phases of endodontic treatment: from the initial diagnostic assessment, through the treatment phase, and finally during posttreatment monitoring.

Overall, organ doses were less than 1 mGy for a single intraoral radiograph for all decades. From todoses to the brain, eye lens, salivary glands, and thyroid decreased by 86, 96, Although digital imaging systems are high tech, a conventional x-ray machine is still needed to expose the image, and the position of the image receptor (sensor or phosphor storage plate [PSP]) in the mouth is identical to positioning with film.

In addition, strict infection control measures must be used because the sensors and PSPs are reused time and again. Intra-oral scanning technology is a very fast-growing field in dentistry since it responds to the need of an accurate three-dimensional mapping of the mouth, as required in a large number of.

Orthodontic tracing • To the fixed anatomical points is applied to assess the nature and extent of any malocclusion which may be present. • Tracing of anatomical landmarks should be drown with sharp, hard (6H) pencil on good quality tracing paper or acetate drafting sheet not on the film and done on film viewer.

The mathematical and optical engineering principles involved in the creation of 3D photogrammetric surface images have been thoroughly described [16,].

The combination of fast acquisition speed and expanded surface coverage (up to degrees) offer distinct advantages over older surface imaging modalities like laser scanning. Introduction. Intraoral periapical radiography is useful in most of dental procedures.

The main indications for this technique include detection of dental caries, periapical pathologies, assessment of periodontal status, assessment of root morphology before extractions and during endodontic procedures, trauma to teeth and the associated structures, and assessment for implant surgery.

All the existing intraoral scanners try to face with problems and disadvantages of traditional impression fabrication process and are driven by several non-contact optical technologies and principles.These instruments are a promising alternative for obtaining direct intraoral impressions in a fast and comfortable way for the patient.

However, they are not indicated for implant rehabilitations requiring more than pieces. Photogrammetry is a novel option for reliable, direct intra-oral registration of the positions of multiple implants. Digital models of 30 subjects were used. InVivoDental (Anatomage, San Jose, Calif) software was used to analyze CBCT scans taken by a Galileos cone beam scanner (Sirona, Charlotte, NC) with a field of view of 15 × 15 × 15 cm 3 and a voxel resolution of mm.
