  • EP 1 529 498 A1 comprises an implant screw which has an internal hexagon, in which a corresponding external hexagon engages the implant structure, so that the implant structure in the implant screw is held against rotation and in a predetermined angular position.
  • EP 1 269 932 A1 discloses a dental implant assembly with an implant screw made of metal, namely titanium, and an implant structure made of ceramic. The implant screw and the implant abutment are connected by a metallic connector.
  • WO 2009/009909 A1 discloses a dental implant with an implant screw and an implant abutment, which are screwed together and additionally glued together. This bonding leads to considerable deficiencies both in clinical use and in the long-term prognosis of the entire system. On the one hand, it is extremely difficult, if not impossible, to reliably remove the exiting adhesive surpluses after bonding. These adhesive surpluses can lead to inflammation at the implant bed and consequently to implant loss. On the other hand, it is sometimes necessary to separate the connection between the implant screw and the implant abutment even after the restoration has been inserted, which is difficult or impossible after the bonding of both components. In addition, in the milieu of the oral cavity, the durability of an adhesive is difficult to predict. Temperature changes, fluctuations in the pH value, mechanical loads and moisture, in particular formerly plastic materials, can age rapidly.
  • the design of the implant screw and / or the implant structure may entail that in certain materials, especially in ceramics or a ceramic-like material or a material containing ceramic or a ceramic-like material, but also in materials containing plastic in different Areas of these components different levels of material collections are available. Due to these different material volumes, it may happen that the finished component is not sufficiently dimensionally stable is. This danger exists in particular if the production process involves a shrinking process, as is the case in particular when sintering ceramics or ceramic-containing materials, but possibly also for materials containing plastic. In general, the shrinkage process is not linear, in particular during sintering. The material of the implant screw and / or the implant structure can thus shrink in different areas of these parts according to the different volumes of material in a different extent.
