  • Publication number: 20150044636
    Abstract: Biocompatible material bars adapted to prevent the interdental bone peak resorption following dental procedures and/or periodontal diseases are described. The biocompatible material bars have different shapes, are made out of biocompatible material and have different surface treatments, which avoid the interdental bone peaks resportion following dental procedures and/or periodontal diseases. The bars of biocompatible material are thin and likewise small-sized in length and width in order to fit the interdental bone size. The bars may have different shapes which make them suitable to be completely inserted into the interdental home, thus matching its shape and size without portions external to the bone. The bars may have surface treatments which favour their implantation and osseointegration.

  • Patent number: 8951043
    Abstract: The invention provides a method for inserting an insertion part of a two-part zirconium-like implant into the jawbone at high force without breaking in order in this way to increase the primary stability of the implant in the jawbone. This is made possible by providing an insertion part at the outside of two or more protrusions at the level of the jawbone line over which an insertion instrument with recesses fits which engages these protrusions in order to subsequently insert the insertion part into the jawbone. The sleeve-shaped insertion instrument with the recesses and the neck of the insertion part with the two or more protrusions can be shaped in such a way that they fit precisely together or that a connection resembling a cardan coupling is produced, so that the implantologist can hold the insertion instrument in various positions above the insertion part while the desired direction of insertion is still maintained.

  • Publication number: 20150037756
    Abstract: The invention relates to manufacturing a surgical guide to be placed in a patient's mouth. The patient's mouth is scanned to obtain surgical-region scan data at a region where an implant is to be located. The patient's mouth is also scanned in the opened position to acquire dental conditions opposite from the surgical region so as to obtain opposing-condition scan data. A virtual model is developed using the surgical-region scan data and the opposing-condition scan data. Using the virtual model, a surgical plan is developed that includes the location of the implant to be installed in the patient. A virtual surgical guide is also developed based on the surgical plan. The dimensions of instrumentation to be used with the surgical guide are checked to ensure they will fit within the mouth by use of the opposing-condition scan data. After checking, final surgical-guide manufacturing information is obtained for manufacturing the surgical guide.

  • Patent number: 8944817
    Abstract: A connection device includes a holding shell and a retention insert. The retention insert has an end side and a substantially ring-shaped retention rim projecting therefrom. The holding shell has an end side and a substantially ring-shaped holding rim projecting therefrom. An outer surface of the retention rim is at least partly spaced from and adjacent to an inner surface of the holding rim when the retention insert is arranged in the holding shell and when essentially no radial forces are acting on the holding rim and on the retention rim. In that the outer surface of the retention rim and inner surface of the holding rim are at least partly not contacting each other when essentially no radial forces are acting, it can be achieved that the retention insert is connected relatively loosely with the holding shell when the connection device has not yet been placed on the implant structure.

  • Patent number: 8939764
    Abstract: A porous metal augment is sized for use in mandibular or maxillar bone. The porous metal material of the augment facilitates and promotes ingrowth of the surrounding bone into the porous metal structure, thereby rebuilding a suitable foundation for affixation of dental implants. A non-porous core or insert can be embedded within the porous metal body of the augment, and can be made of a material suitable for firm threaded fixation of dental implants thereto. For example, the metal core can be formed of a titanium structure that has sufficient strength and resiliency to form a firm and long lasting threaded connection with a threaded stem of a dental implant.

  • Patent number: 8936467
    Abstract: Method for extracting an implant installed in a bone, which comprises the application of a torque on an extraction tool in order to thread it in the interior of the implant until the implant-bone connection is broken, with the specific feature that the torque is applied in phases. In each phase a torque that is increasingly greater than in the previous phase is applied and the application of torque is then eased. This method brings about a gradual and controlled deformation of the head of the implant, with the result that the extraction tool is inserted more deeply into the implant. As a result, higher breakage torques may be applied without damage being caused to the extraction tool.
