  • Patent number: 11723756
    Abstract: A receptacle for a dental implant includes a cover with a first end section which is open to the outside and a second end section which is closed to the outside. The cover surrounds an interior space which is open to the first end section and in which a holder is arranged. The holder has a channel that is open to the outside and is formed to hold an implant extension during transport. The receptacle has a tubular bottom receptacle including an outer third end section and an opposing fourth end section. Three spring arms are arranged in the cover at an outer first end. The spring arms are so designed that the nubs thereof are pushed away during insertion of the implant extension and, in the final position, push into the groove with a tensioning force.
