Screwing a head bolt for attaching an abutment for a dental restoration to an implant body

摘要

It is a screw device for a head screw (9) for fixing an abutment (8) for a tooth structure (15) on an implant body (7) having a female thread (11) for the abutment (8) passing through the head screw (9), described using a spanner (2), the a in a chuck (1) insertable shaft (3) and one in a plug receptacle (13) of the cap screw (9) insertable plug-in projection (4) on the shaft end. In order to create advantageous design conditions, it is proposed that the plug-in projection (4) is connected to the shaft (3) via a breaking at a predetermined load torque predetermined breaking point (5).
