What are vertical Bitewings used for?
A series of seven vertical bitewings allows for the capture of both anterior and posterior teeth. The usual protocol is to take three bitewings on each side and then one for the anterior. Properly taken vertical bitewings deliver better diagnostics by providing a comprehensive view of the full mouth.
Where do sensors go on Bitewings?
For a molar horizontal bitewing view, the bitewing tab should be centered on the sensor and placed behind the molar teeth.
When should I take vertical Bitewings?
Vertical bitewings are often indicated in patients where current or past periodontitis is suspected so as to better reveal the relationships of the teeth to interproximal crestal bone levels.
What teeth do Bitewings show?
Bitewing X-rays show details of the upper and lower teeth in one area of the mouth. Each bitewing shows a tooth from its crown (the exposed surface) to the level of the supporting bone. Bitewing X-rays detect decay between teeth and changes in the thickness of bone caused by gum disease.
What is the correct position of the sensor for a mandibular premolar image?
Because of the mandibular symphysis, the bisecting angle technique is used to produce radiographs of the rostral mandibular premolars. The patient is placed in dorsal recumbency with the skull parallel to the table. The sensor or film will be placed parallel to the table between the maxillary and mandibular premolars.
How do you set the vertical angulation?
-Vertical angulation is directed perpendicular to the image receptor at approximately +10 degrees with the PID tilted downwards. Central Ray is directed at the center of the image receptor at a spot on the incisal plane between the maxillary and mandibular teeth.
How is the vertical angulation of a bitewing determined?
Vertical BitewingVertical bitewing films can be taken using tabs or abitewing instrument, just as with regular bitewings.The vertical angulation is +10° with tabs; the PID isaligned with the ring when using the instrument.The horizontal angulation is determined in the samemanner as it is with regular bitewings.
Which is the correct position for the bitewing technique?
Bitewing Technique Film Position (Same for tabs or Rinn BW instrument)The premolar bitewing film is approximately centered onthe 2nd premolar; the front edge of the film should be atleast in the middle of the canine.
What does a vertical bitewing X-ray show?
In children and adolescents, they also show developing permanent teeth. Taken with the film or sensor place in a vertical direction (vertical bitewings), these radiographs also show bone volume and density, for evaluation of periodontal health (“peri” – around; “odont” – tooth).
What are the pros and cons of vertical bitewings?
Vertical bitewings — Common recall film for periodontally involved patients. Vertical bitewings provide a more in-depth view of not only interproximal areas, but a more detailed picture of the periodontal structures. Pro: Able to see more perio than the traditional BWX. Con: Unable to see apex.
