Definition:
the only x-ray that is taken without a precision(tm) x-ray holder. The x-ray film for this procedure is shaped like a large oatmeal cookie. You are asked to bite on the x-ray film and the top of the x-ray machine is positioned over your nose for a maxillary occlusal x-ray or under your chin for a mandibular occlusal film. The x- ray shows the whole arch.
