Abstract

Abstract The invention relates to an image plate (1) for intraoral dental radiography which can be closed within a cover through which X-rays can pass, where the plate is retained during the X-raying and from where the plate can be removed after the X-raying in order to read the picture. According to the invention the edges of the image plate (1) are equipped with a protective frame (2) projecting from the plane of the plate surface at least on the image side of the plate. The frame may be formed as a continuous cover frame (2) surrounding the edges of the frame, consisting of two opposite frame-like portions (7) pressed together and optionally identical. The purpose of the frame (2) is to protect the image plate (1) against scratches or similar damages as the plate is being handled and read.
