Disclosed is an intraoral radiographic system includes an intraoral sensor including a sensing surface for receiving X-rays and a coupling protrusion, and a sensor indicator including a sensor coupler configured to fasten the coupling protrusion detachably, and a support body supporting the sensor coupler. The sensor coupler is configured to be engaged with the coupling protrusion by applying an elastic force, and has a stopper preventing from sliding of the intraoral sensor.

A multi-configurable dental radiograph sensor holder system includes a handle having a long portion and a short portion at right angle to each other. An aiming ring is coupled to the long portion and a sensor holder is coupled to the short portion by a sensor positioning ring that is coupled to the short portion of the handle through a hinge linkage. The hinge linkage is articulable in the plane of the aiming ring and allows the sensor to be moved into different positions relative to the aiming ring in order to collect anterior, posterior, and bite wing views of a patient's dentition.

A universal digital dental x-ray sensor holder with adjustable aiming apparatus is provided for holding a digital dental x-ray sensor in a desired location by an apparatus enabled by this disclosure. The universal digital dental x-ray sensor holder with adjustable aiming apparatus may include an aiming module, guide rail, slider, arm, sensor attachment module, compression accessory and sensors and interchangeability of same. A method for holding a digital dental x-ray sensor in a desired location by an apparatus enabled by this disclosure using the universal digital dental x-ray sensor holder with adjustable aiming apparatus is also provided.

An X-ray aiming ring apparatus includes an aiming ring defining an opening, and a connector including a first extremity defining an inlet, a second extremity defining an outlet, and an X-ray beam channel through the connector from the inlet to the outlet. The connector extends outward to the first extremity from the second extremity connected to the aiming ring, the X-ray beam channel is open to the opening by the outlet, and the first extremity is configured to connect mechanically to an X-ray machine position-indicating tube having an open discharge end and arranged about an X-ray beam centerline, to open the X-ray beam channel to the open discharge end by the inlet and axially align the open discharge end, the inlet, the X-ray beam channel, and the outlet along the X-ray beam centerline.
