title: [A variant of the Eggens filmholder for use in the posterior molar region].
abstract: Dr. Eggen's filmholder for long-cone-paralleling-technique is today available in two new, supplementary devices. These devices have an angulation in the metal rod, see fig. 1, and are meant to facilitate the film-positioning in the 3rd-molar area. A test was carried out to evaluate the new film-holders. Pairs of radiographs were taken in all 3rd-molar-areas, one radiograph with the straight film-holder, one with the angled device. Difference in horizontal film-position was measured. The results showed that in 93% the most posterior film-position was obtained with the angled film-holder.
