Bite-Wing Receptors

Question 1

How many sizes are there for the bite-wing receptors?

Answer 1

3: 0,2,3

Question 2

What is the size 0 used for?

Answer 2

To examine the posterior teeth of children with primary dentition. This receptor is always placed with the long portion of the receptor in a horizontal direction.

Question 3

What is the size 2 used for?

Answer 3

To examine the posterior teeth in adults and may be placed horizontally or vertically. For most bite-wing exposures, a size 2 receptor is placed with the long portion of the receptor in a horizontal direction. When a vertical posterior bite-wing exposure is indicated, a size 2 receptor is placed with the long portion of the receptor in a vertical direction.

Question 4

What is the size 3 used for?

Answer 4

Used ONLY for bite-wing exposures. One receptor is exposed on each side of the arch to examine all the premolar and molar contact areas. A size 3 receptor is placed with the long portion of the receptor in a horizontal direction.

Question 5

What tends to happen for size 3 receptors?

Answer 5

With a size 3 receptor, overlapped contacts often result because of the difference in the curvature of the arch between the premolar and molar areas.
