  • the screw connection may at some time be released at least to the extent that a possible rotation of the implant about the screw-in axis can not be permanently prevented.
  • the position of the attachment (the screw) is already defined by the given geometry of the implant. This has the consequence that the implant can not be used if necessary, because in the region of the attachment nerves and / or existing teeth are present, which by attaching the
  • Implant damage by means of the screw In the event that existing, intact teeth hinder attachment of the implant, they must also be removed and replaced with artificial teeth.
  • Bone structure be reconstructed in advance, for example, by replacing the missing structures with bone from the iliac crest or from the patient's fibula. This requires hospitalization of the patient.
  • the implant has structures, such as. Holes with internal thread, which are prepared to receive one (or more) so-called abutment base. These are usually screwed into the structures provided.
  • Abutmentsockel is in turn prepared for receiving a so-called abutment, which serves to receive an artificial denture. This means that the denture is connected to the implant via abutment base and abutments.
