Radiopaque dental compositions, radiopaque dental markers, and methods for making such markers are described, as well as kits containing combinations of, inter alia, the markers, molds for making the markers, and materials for sculpting the markers. The compositions contain a radiopaque material, for example diatrizoate sodium, in a polymeric binder. The markers may be in the shape of teeth, and can be sculpted or ground to conform to a patient's gingival surface and to occlude with an opposing tooth. The marker can then be placed in a stent for purposes of making radiographs of a patient's mouth from which an oral surgeon can determine the optimal placement of a permanent dental implant. |
