摘要： A process for manufacturing a head piece (1) of a tooth implant from an individually produced positive model (27). The head piece (1) is fitted with a plug-in type connection shaped with form-closure (7) as an anti-twist feature and can be inserted into the base (3) which in turn can be embedded in the jawbone. On either head piece or base there is a lug (5) which fits snugly into a socket on the other part. The process calls for copy-milling (V) in which the outer surface of the positive model (27) is three-dimensionally scanned. The data from the scan are used to guide a milling machine which creates the head piece (1) from a ceramic blank (29). In accordance with the invention, before the copy-milling (V) of the blank (29), a preparatory step (I) in the production process is conducted. When the blank is yet in its raw form, the insertion connector with the form-closure (7) connection is shaped ahead of by attaching a scanning insert on the positive model (27) at a point matching the position of the insertion connector on the blank, which enlarges the positive model by at least as much space (a) as that to be occupied by the insertion connector.
