Using the RVG Sensors

Acquiring Bitewing Images

Use the following techniques for horizontal and vertical bitewing images. The bitewing should provide a clear view of the proximal surfaces, the crowns of the teeth, and the alveolar surfaces. It is imperative that you avoid horizontal overlap.

Horizontal Molar Bitewing

To acquire a horizontal image of a molar:

  1. Place the sensor in the patient’s mouth in a horizontal position.

  2. With a sweeping motion, position the sensor between the tongue and the teeth. Use the rigidity of the sensor to push the tongue out of the way.

  3. If the patient has a shallow vault, place the sensor as close to the midline as possible.

  4. Position the sensor so that its posterior edge is behind the most posterior molar.

  5. Ask the patient to close his mouth gently.

  6. Align the beam indicating device.

  7. Move into position and acquire the image.

Horizontal Premolar Bitewing

To acquire a horizontal image of a premolar:

  1. Place the sensor in the patient’s mouth in a horizontal position.

  2. Position the anterior edge of the sensor at the center of the mandibular canine so you can capture the interproximal contact of the premolar and canine.

  3. Bring the beam indicating device mesially so that it is almost centered on the canine. The sensor should be almost perpendicular to the cone beam.

  4. Ask the patient to close her mouth gently.

  5. Align the beam indicating device.

  6. Move into position and acquire the image.

Vertical Molar Bitewing

To acquire a vertical image of a molar:

  1. Place the sensor in the patient’s mouth horizontally, and then rotate it into position.

  2. Place the sensor as close as possible to the patient’s midline.

  3. Position the sensor so its anterior edge is behind the distal surface of the second premolar.

  4. Ask the patient to close his mouth gently.

  5. Align the beam indicating device.

  6. Move into position and acquire the image.

Vertical Premolar Bitewing

To acquire a vertical image of a premolar:

  1. Place the sensor in the patient’s mouth horizontally, and then rotate it into position.

  2. Position the sensor so the anterior edge is behind the distal surface of the lateral incisor.

  3. Make sure the anterior edge of the sensor is also centered behind the mandibular canine.

  4. Ask the patient to close her mouth gently.

  5. Align the beam indicating device.

  6. Move into position and acquire the image.
