  • Dental x-ray aiming device with marginal ridge indexing
    Patent number: 9095289
    Abstract: The present invention is a device for aiming a dental x-ray beam to be centered parallel to the area of contact between two adjacent teeth so that the resultant bite wing radiographic image is one that shows at least those two teeth as distinct and not superimposed images. The device, comprising a marginal ridge angulation locator that indexes into the substantially v-shaped groove on the biting surfaces between two adjacent teeth, locates and indicates an aiming vector centered over and parallel to the area of contact between those two teeth for the purpose of aiming an x-ray beam then exposing the radiographic image desired.
