ABSTRACT:
The anchorage equipment for an artificial tooth comprises a cap made of a gold alloy which is adapted to be stuck onto the head of the root canal anchorage post. The porcelain build-up can be applied to this cap directly by molding. The head of the root canal anchorage post comprises a pin haaving a laterally flattened portion, and the plug-on cap has a corresponding bore provided with a flattened portion for the purpose of mutual alignment. The equipment further includes a transfer cap and a transfer pin having the same alignment feature as the above-mentioned pin and cap. For the production of an artificial tooth, first an impression is taken with the transfer cap plugged on, then a gypsum impression is prepared with the transfer pin inserted into the transfer cap, whereupon the dental technician can proceed to stick the cap onto the projecting transfer pin in order to form the porcelain crown directly on the cap. Finally, the dentist cements the finished artificial tooth including the cap to the root canal anchorage post. Such an equipment greatly facilitates and simplifies the production of an artificial tooth, and not only a shorter and substantially more acceptable procedure for the patient results, but also a reduction of expenses.
