Ow-RX

(Rev. 6)

10.2

Typical defects caused by incorrect positioning

•

X-rays with elongated or shortened images

The X-ray beam is not perpendicular to the bisector of the angle

formed by the longitudinal axis of the tooth and by the film.

•

X-rays with the top of the tooth elongated

Probably caused by the excessive folding of the film in the

patient's mouth.
