  • Publication number: 20100285428
    Abstract: This describes an implant design that increases the amount of bone around the implant by increasing its length in order to place a longer implant without the need for a sinus elevation surgery in the posterior maxillary region where bone stock is not sufficient by employing the principles of displacement procedures in implantology which rely on regeneration of patient's own bone and have been used for years in the dentistry for orthodontic procedures. The implant system we have designed has a pressure adaptor (4) that protrudes and advances through the apical part of the implant. Pressure adaptor (4) is advanced within the bone until desired length of implant and bone is achieved. This procedure forms significant amount of bone around the implant within the floor of maxillary sinus. Floor of maxillary sinus is elevated. New bone is formed without the need for an additional surgery.

  • Patent number: 7780447
    Abstract: A dental implant assembly for supporting a dental prosthesis. The assembly comprises a dental implant and an abutment. The dental implant comprises a body portion, a collar portion and a central bore. The body portion is located at a distal end of the dental implant and is configured to lie at least substantially below a crest of a patient's jawbone. The collar portion is located at a proximal end of the dental implant and forms an abutment mating surface which defines an outer edge that has a generally scalloped shape. The central bore extends through the collar portion and into the implant body portion. The central bore includes a threaded portion and a post portion. The abutment comprises a post configured to fit within the post portion of the central bore and an implant mating surface that is configured to mate with the abutment mating surface of the dental implant.

  • Publication number: 20100209874
    Abstract: The arrangement for forming a bar construction, to which a prosthesis can be fastened, may comprise: a first connecting element with a first end which has a through-opening through which an end of a fixation screw can be passed in order to fasten the first connecting element in a specific angular position in relation to an implant, and a second end which is connectable with a bar, and a second connecting element, which is connectable by a releasable connection to the first connecting element, and securing means for counteracting a separation of the two connecting elements from each other when these are connected and moved. The two connecting elements may each comprise an end that has a substantially spherical inner face and a substantially spherical outer face. The head of a fixation screw may have a first substantially spherical outer face and a second substantially conical outer face.

  • Publication number: 20100167242
    Abstract: A dental implant has a plurality of tiers each having a non-circular outline. Each tier has maximum dimensions of its respective outline along two transverse axes. The maximum dimensions of a given tier are smaller than the maximum dimensions of an adjacent tier. Accordingly, the tiers taper generally from a larger outline to a smaller outline in a vertical direction from a top well to an opposing bottom of the implant. An abutment may be received on the implant.

  • Publication number: 20100167241
    Abstract: A dental implant assembly comprises an implant, a driver/abutment device, and a spacer. The device includes a bottom portion having a protrusion comprising an inferior aspect and a superior aspect. The spacer prevents the oversized, superior aspect of the device from engaging an interior cavity of the implant so that the driver is easily removable after insertion of the implant in the jaw of a patient. Removing the spacer permits the superior aspect to engage the interior cavity, thereby permanently fixing the driver to the implant.
