title: New device to quantitate alveolar bone loss.
abstract: The advantages of the device described here are that (1) it produces sharp grid outlines on the film that can be accurately measured, (2) distortion factors can be compensated so that an accurate measurement can be obtained of any bony changes, and (3) the patient is exposed to radiation only once and two films are produced with and without the grid.
