About bite block positioners
An x-ray bite block is the part the patient closes on; it falls under the FDA section for devices that position and hold x-ray film inside the mouth. Covers go over a block that is reused: the guidance names heat-sterilizable or disposable receptor-holding devices for infection control. The same guidance states that dental professionals should not hold the receptor holder during exposure.
A holder is what keeps the image receptor still in the mouth: the FDA calls it a dental x-ray film holder, a device intended to position and to hold x-ray film inside the mouth, and lists it as Class I (21 CFR 872.1905). A second section covers the dental x-ray exposure alignment device, intended to position x-ray film and to align the examination site with the x-ray beam. The aiming part at the tube end is a position indicating device — a collimator, cone or aperture that aligns the examination site with the beam and restricts the dimensions of the x-ray field by limiting the size of the primary beam.
FDA and ADA guidance names holders that align the receptor precisely with the collimated beam for periapical and bitewing radiographs, and heat-sterilizable or disposable receptor-holding devices for infection control. Using a receptor-holding device reduces the risk of cone-cutting, where part of the receptor is not exposed because the beam is out of line. Published work describes the paralleling technique as producing the most accurate periapical radiographs for endodontic purposes, and notes that a film-holding device used with it standardises the images.
How positioners and bite blocks differ
- Positioners & Aiming Devices — The arm and ring that aim the beam, which is what makes the paralleling technique repeatable. In one comparison an angulation-adjustable holder produced no cone-cutting error in the horizontal tube-shift technique and cut the time spent aligning the cone, where a fixed right-angle paralleling holder did not.
- Bite Block Positioners — Held in place by the bite, with no aiming arm or ring of its own.
What to look at when choosing a positioner
Receptor size: standard receptor dimensions are 22 by 35 mm for size 0, 24 by 40 mm for size 1, 31 by 41 mm for size 2, 27 by 54 mm for size 3 and 57 by 75 mm for size 4.
Projection: the guidance names holders for periapical and bitewing radiographs, and a holder is matched to the view it is used for.
Collimator shape: a clinical audit reported that rectangular collimation reduces the patient dose on intraoral radiographs by 40 to 92 percent against round collimation, and that no cone-cuts occurred when it was used. For adult intraoral imaging the beam at the end of a rectangular collimator is described as ideally limited to no more than 35 by 45 mm.
Reprocessing: a holder is either heat-sterilizable or disposable.
The cone it works with: guidance states the position indicating device should be open ended and have a metallic lining, to restrict the primary beam and reduce the tissue volume exposed to radiation. A lead-lined position indicator is its own Class I device: a cone-shaped device lined with lead, attached to the tube, that absorbs divergent radiation and prevents leakage.
