Abstract

The invention discloses a bite-type oral periapical film projection positioning frame which comprises a functional end and a hand-held end for fixing an image plate. The functional end and the hand-held end are connected by a bending part, when front teeth are shoot, the bending part is used to be bite by the teeth for positioning. The bite-type oral periapical film projection positioning frame can be used to shoot the projection images of the front teeth as well as the projection images of back teeth. During the shooting process, the image plate is inserted into the inner side of the to-be-shoot teeth of a patient through the hand-held end, the angle of the image plate is adjusted, then the front teeth of the patient bite the positioning frame, and the image plate is fixed through bitingof the front teeth. Hands of the patient can be completely liberated, the hospital infection problem of touching the perioral tissues at the time of holding by the patient is effectively solved, the problem of floating of the image plate caused by the instability of hand-holding is solved, the inaccurate angle and motion artifacts caused by tooth and tooth tip interference and moving are removed,the fixation through the bite is more stable, and the shooting quality is further improved accordingly.

Description

technical field [0001] The invention relates to oral and maxillofacial imaging technology, in particular to an occlusal oral apical film projection positioning frame. Background technique [0002] In recent years, the radiology departments of national stomatological hospitals have gradually started to use various types of positioning frames / holding frames (clips) in the daily oral periapical film shooting process. Generally, a straight rod type is used, and the long axis or short axis direction of the image imaging plate at the functional end is usually placed in the same or parallel direction as the long axis of the straight rod, such as a clip type or an insert type. That is, one end of the positioning frame adopts a slot type, a clip type, etc. to fix the image imaging plate used to receive the image information generated by X-ray projections on the teeth, and the X-ray exposure is to project the image of the teeth after projection on the image plate. The other end of th...
