ABSTRACT:
The invention relates to a dental instrument for optimal positioning of an X-ray film support in the X-raying of teeth, especially front teeth, or adjacent tissues. The instrument comprises a bridge having at its one end which is located in the patient's oral cavity inside the subject to be X-rayed a holder keeping the film positioned perpendicularly to the longitudinal axis of the bridge and means receiving an alignment rod which is parallel to the longitudinal axis of the bridge and which projects outside the oral cavity whereby the optical axis of the X-ray camera can be positioned relatively the rod and hence relatively the film. The instrument is improved by means of a transverse support arm connected to the bridge and adapted to be held pressed between the teeth in the upper and lower jaws permitting rotation of the film holder around the geometric longitudinal axis of the support arm. The end portions of the arm are connectable to bite block means permitting rotation of the device around the longitudinal axis of the arm.
