  • Patent number: 12193909
    Abstract: A dental implant with an implant extension that are formed along a longitudinal axis. The dental implant has apical and coronal ends and a section for receiving and securing an abutment. The implant extension is formed in one piece with the implant and extends away from an end face of the apical end along the longitudinal axis. The implant extension has a first section along the longitudinal axis with an annular constriction directly connected to the apical end face of the implant. The implant breaks off from the implant extension at the constriction. The second section and splined shaft section are arranged along the longitudinal axis following the first section so as to be further away from the implant than the first section. The second section includes an outer annular groove that is designed to be clamped in the direction of the longitudinal axis to hold the implant extension.

  • 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.

  • Patent number: 10634485
    Abstract: A device for contactless optical distance measurement includes a polychromatic light source, a light analysis unit and a measurement head. The measurement head has an aperture opening and an optical lens system, which has a chromatic longitudinal aberration. The optical lens system includes a first refractive lens element and a second refractive lens element. At least one of the refractive lens elements has at least one aspherical lens surface, and the first refractive lens element and/or the second refractive lens element has an optical material with an Abbe number 20<=Vd<=41. The optical lens system has such a chromatic longitudinal aberration that a measurement region, which equals an axial focal shift of the optical lens system between the wavelengths of 450 nm and 700 nm, is between 0.2 mm inclusive and 10 mm inclusive.
