A method for producing a holding apparatus for an x-ray film for teeth of a patient. The method includes performing an image registration of a first two-dimensional x-ray image of a tooth of an upper or lower jaw in a three-dimensional volume-tomographic data record of a jaw with a computer, determining a relative position of the first two-dimensional x-ray image within the three-dimensional volume-tomographic data record, preparing a virtual model for a holding apparatus that is attachable to the teeth of the upper or lower jaw in an interlocking fashion on the basis of the three-dimensional volume-tomographic data record, and producing the holding apparatus based on the virtual model. The holding apparatus includes a holding element which holds the x-ray film in a defined position. The defined position is established by the relative position of the first two-dimensional x-ray image in the three-dimensional volume-tomographic data record.
