Abstract
An intra-oral dental radiological image sensor is mechanically reinforced by two front RA and rear RB mechanical reinforcing plates each inserted between a respective face of an image capture module and a respective front 20A and rear 20B shell bottom of a casing. The front reinforcing plate is a solid plate, made of material transparent to X rays, covering the photosensitive front face (scintillator) of the module, and harder than the front shell. The rear plate, less thick than the front plate, is harder than the rear shell and comprises an opening O provided to surround, without covering them, components present on the rear face of the module, under a rear shell dome.
