  • Patent number: 11058522
    Abstract: The present invention discloses a dental implant (30; 130; 230; 330; 430) for preserving soft tissue and promoting bone growth, including an elongated implant body having a coronal end portion (31; 131; 431) and an apical end portion (32; 132; 332; 432); an external thread (40; 140; 240; 440); a flute arrangement (50; 150; 350; 450) having at least one helical flute having a depth; in which the apical end portion forms a blunt tip (39; 139; 339), and in which the helical flute spirals in opposite direction to the external thread, and the flute exits on the face of the blunt tip.

  • Patent number: 10603140
    Abstract: It is disclosed a dental implant (130; 230; 330) for promoting hone growth. The dental implant includes an elongated implant body having a coronal end portion (131; 231; 331) and an apical end portion (132; 232; 332), at least one external thread (140; 240; 340) and a flute arrangement having a depth. The flute arrangement has at least two helical flutes (150; 250; 350) that spiral in the general direction of said at least one external thread (140; 240; 340). The flutes (150; 250; 350) propagate with a greater lead than said at least one thread (140; 240 340). The flute arrangement is capable of scraping off and transferring bone debris in the coronal direction of the implant during insertion. It is also disclosed a method of using the dental implant and an implant system according to the present invention.

  • Patent number: 7491058
    Abstract: A spacer (3) with associated adapter (4) is designed to be fitted on an implant (1). The adapter comprises first and second portions (4b, 4c) designed to cooperate with the spacer and the implant, respectively, for securing the spacer on the implant. The adapter is completely enclosed by the spacer and the implant, and the first portion of the adapter can be designed with slits for forming resilient elements on said portion and/or with penetrating parts which, when the adapter and the spacer are joined together, are deformed as it penetrates into opposite parts in the spacer material. The spacer and the adapter can in this way be easily held together upon application to the implant and can be taken apart when completion work is performed on the spacer.
