A sensor positioner for use with a dental digital radiography system includes an x-ray source which transmits through an x-ray cone an x-ray stream which has a generally circular cross-section and an intraoral sensor which is aligned with the x-ray source. The sensor positioner includes an aiming ring and a sensor carrier. The aiming ring includes a receptacle which is a single hole having a predefined cross-sectional shape with two axes of symmetry wherein the aiming ring is capable to being disposed adjacent to and visually aligned with to the x-ray source through the x-ray cone. The sensor carrier includes an attachment rod which has a first end and a second end and which has the same shape as the receptacle of the aiming ring so that the receptacle receives the attachment rod at the first end in one of two ways. The sensor holder is coupled to the second end of the attachment rod to integrally form the sensor carrier. The sensor holder has a surface on which the intraoral sensor is placed which visually aligns the intraoral sensor and a clip which secures the dental sensor to the surface so that the intraoral sensor does not slide relative to the center of the aiming ring.
