Intra-Oral X-ray This idea is also about a tray that can be used to take x-rays. It is quite similar to EIT trays.
These X-ray trays do not have posterior wall (Vibratory Line) or walls covering the retromolar pad, just like the regular impression trays. The remaining walls are little thicker to provide space or distance for the exposure. The external portion of the walls is connected to the small cords. These cords are attached to tiny little boxes which produces x-ray beams. These boxes are attached to the trays and are very close to the subject (the tooth).
Electrical currents are made to travel through the cords directing towards the boxes where the x-ray beams are produced. These boxes are in close approximation to the tooth. As soon as the beams are produced, it is directed towards the tooth. This will allow less scattering of the beams. One cord will represent one box for one tooth or two tooth areas.
The palatal portion of the X-ray tray would be provided with flexible rubber material that holds the x-ray sensors firmly against the palate. For this tray there can be made a special sensor which is long and adapted to these x-ray trays or we can simply make use of current periapical digital sensors.
Each cord will be connected to a controller and each cord will be named according to the tooth or the tooth area. For example, the cord that will expose right upper central incisor area will be named as CORD # 11.
We can make use of new long x-ray sensor adapted to the x-ray tray to expose all the teeth simultaneously or we can expose only few teeth through the controller. On the controller, the cords representing the teeth to be exposed will be activated while all the rest of the cords will be deactivated.
The x-ray trays are large enough to rotate within the oral cavity to be able to expose the tooth for Buccal Object Rule (BOR).
A lead mask is provided that covers the mouth and neck all around. This helps the rays to be limited within the oral cavity.
No angulations problem.
The size of the image will be close to the size of the exact tooth because the rays are in close proximity to the tooth.
X-ray hazards which diverge from the current PID can be limited.
