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.

A custom tool for forming a dental restoration in a mouth of a patient includes a custom tool for forming a dental restoration in a mouth of a patient comprising: a mold body for a patient-specific, customized fit with the facial side and the lingual side of at least two adjacent teeth of the patient, and a flexible film, wherein the mold body is configured to combine with the flexible film to form a mold cavity encompassing missing tooth structure of at least one tooth to be restored.

A dental separator device includes an elastic body having a first end and a second end. A first surface engager is connected to the first end of the body. The first surface engager includes a first distal section and a first mesial section and a notch between the first distal section and the first mesial section. The first distal section and the first mesial section each include a pair of spaced apart hands. A second surface engager is connected to the second end of the body. The second surface engager includes a second distal section and a second mesial section, and a notch between the second distal section and the second mesial section. The second distal section and the second mesial section each include a pair of spaced apart hands. The hands are for engaging teeth and/or for creating adaptation pressure on a dental matrix stabilizer and/or dental matrix.

A dental stent for tooth restoration, includes an acrylic outer shell and a set of metal matrix separator strips partially embedded into an inner silicon bed. A method of manufacturing a dental stent includes 3D printing of a model wherein tooth forms of teeth to be restored are individually removable from a remainder of the model. A method of tooth restoration uses a dental stent, and a kit of parts including a dental stent and a composite resin, and optionally a heater, a light cure unit, and a finishing tool kit.
