[29] Select an answer and submit. 10.7). with bone loss caused when the central ray of the xray is not directed through the contact areas of teeth, what is seen on the resulting images? patient's name and the date the images were exposed. contacts of the teeth, All Rights Reserved. The patient is asked to close the teeth firmly together onto the bite platform. When a size #2 film sensor is used, the anterior films are in the ______ position, and the posterior films/sensors are in the ______ position. using a +10 degree what condition is detected by the primary use of bite-wing images? Equipment Preparation, receptors are Receptor placement In clinical cases where periodontitis exists or is suspected, vertically positioned BWs allow the best view of the alveolar crest, and are recommended. The image receptor should be positioned centrally within the holder with the upper and lower edges of the image receptor parallel to the bite-platform. includes the crowns of maxillary and mandibular teeth, interproximal areas, and areas of crestal bone on the same image. when patients have small mouths or low palatal vaults. The beam-aiming device should ensure that in the vertical plane, the X-ray tubehead is aimed downwards (approximately 58 to the horizontal) to compensate for the upwardly rising curve of Monson (Fig. Multiple factors influence the selection of radiographic techniques for a particular case including cost, availability, radiation exposure, and patient's ana Use LEFT and RIGHT arrow keys to navigate between flashcards; Use UP and DOWN arrow keys to flip the card; audio not yet available for this language, Describe the purpose and use of the bite-wing image, a method used to examine the interproximal surfaces of teeth (contact point of teeth), Describe the appearance of opened and overlapped contact areas on a bite-wing image, contact areas- where adjacent tooth surfaces meet, State the basic principles of the bite-wing technique, -Place receptor parallel to the crowns of both the maxillary and mandibular teeth, List the two ways a receptor can be stabilized in the bite-wing technique and identify which one is recommended for bite-wing exposures, List the three receptor sizes that can be used in the bite-wing technique and identify which size is recommended for exposures in the adult patient, -size 0: for posterior teeth of children w/ primary dentition placed horizontally, Describe correct and incorrect horizontal angulation, Describe the difference between positive and negative vertical angulation, State the recommended vertical angulation for all bite-wing exposures using a bite-wing tab, +10 degrees, if less, results in a distorted image, State the basic rules for the bite-wing technique, Describe patient and equipment preparations that are necessary before using the bite-wing technique, Discuss the exposure sequence for a complete mouth radiographic series (CMRS) that includes both periapical and bite-wing exposures. The dental assistant exposing a periapical film sensor using the paralleling technique, should always start with the anterior teeth, 12. the tongue. 4 refers to the up-and-down plane The bite-wing receptor has a "wing," or tab, and the patient "bites" on the wing to stabilize the receptor, bone that supports and encases the roots of teeth, Coronal portion of alveolar bone found between the teeth, The area of a tooth that touches an adjacent tooth; the area where adjacent tooth surfaces contact each other, The bite-wing receptor is placed in the mouth with the long portion of the receptor in a horizontal direction, on a dental image, opened contacts appear as thin radiolucent lines between adjacent tooth surfaces. When taking radiographs using film, the white side of the film is always placed, For the patient with a hypersensitive gag reflex, the teeth that should be exposed last are, Factors that can affect the quality of dental radiographs include. Expose all anterior periapical receptors first. Alveolar bone In adults, a size #___ intraoral film is used for the occlusal technique. +10 angulation recommended for bitewings, positive = if central ray directed downward Equipment must also be prepared before the dental image can expose any films. Power: 2700 W Add, edit, delete clues, and customize this puzzle. An individual image is designed to show the crowns of the premolar and molar teeth on one side of the jaws. vertical direction We weren't able to detect the audio language on your flashcards. 9 7. Exposure Sequence for The desired holder is selected together with an appropriate-sized image receptor typically a 31 41mm film packet or phosphor plate or the equivalent-sized solid-state sensor. You, How would you characterize the damage seen on the nose of this individual? Even occlu Incisors may seem to have normal overbite, but their correction by simple tipping may produce a deeper bite. To correct an elongated image on an x-ray view, the vertical angulation needs to be ______. the receptor stabilized when the patient bite on the bite-wing tab or the bite-wing beam aligment device. patients can tolerate the film sensor size easier. Placed with the long Rules of bite-wing technique What is the basic principles of the bite-wing technique ? horizontal angulation Crestal bone 14 Describe the vertical bitewing and indications for use. receptor. 14. the horizontal and vertical planes Five basic rules must be followed when using the bite-wing technique. In the posterior bite-wing series, the receptors are placed 15 3. A)film sensor is placed parallel to the crowns of the teeth.B)blue Rinn type holder is used to stabilize the film sensor in the patient's mouth.C)central ray is directed through the contacts of the teeth using +10 degrees horizontal angulation.D)angulation of the PID is not a factor in the bitewing technique. Interproximal The anterior edge of the image receptor should be positioned opposite the distal aspect of the lower canine in this position the image receptor extends usually just beyond the mesial aspect of the lower third molar (see, The patient is asked to close the teeth firmly together onto the bite platform. ), a four-receptor posterior bite- Question -1 Bite wing radiograph technique are mostly used for identifying interproximal caries as well as evaluating the level of alv.
