20090240289Orthodontic Anchoring Screw - An orthodontic anchorage screw (09-24-2009
20090258327SURFACE AREA OF A CERAMIC BODY AND CERAMIC BODY - Disclosed is a dental implant with a post element that can be inserted into a jawbone and with a mounting element attached to the post element, to which mounting element and dental element can be affixed with the post element designed as a ceramic body of yttrium and/or aluminum oxide stabilized zirconium oxide. Said dental implant should have an even additionally improved ingrowth or integration behaviour during the osseous implant healing, compared with the mentioned known concepts. According to the invention, the surface of the dental implant is provided with at least one partial area that has nanoscopic pore or an otherwise executed nanoscopic structure that has a depletion zone with a reduced yttrium and/or aluminum oxide element, compared with the internal volume.10-15-2009

20100196853DENTAL IMPLANT AND METHOD FOR PROVIDING A MOUNTING PART - A dental implant with a post part which can be introduced into a jaw bone and with a mounting part assigned to this, on which a dental prosthesis piece can be mounted, is said to allow the dental technician to choose a particularly favourable orientation for further assembling of the components, and at the same time to make it possible for the person performing the treatment to make use of the advantages of an indexing without using auxiliary tools (e.g. individual keys). For this, according to the invention the mounting part is configured in a plurality of pieces and, in addition to a first mounting part piece which, viewed in the longitudinal direction of the post part, can be pushed into a receiving channel arranged in this, comprises a second mounting part piece which is envisaged for assembling the dental prosthesis piece and can be brought into positive locking contact with the first mounting part piece in a contact region with an essentially circular cross-section, wherein the internal contour of the receiving channel, like the external contour of the first mounting part piece tailored thereto, has a multi-membered symmetry in cross-section.08-05-2010
20100304337LABORATORY IMPLANT - A method for the production of a dental implant with a post part which can be introduced into a jawbone and with a mounting part assigned thereto, on which a dental prosthetic piece can be mounted, is to allow the dental technician to perform a simple indexing of the mounting part while drawing on current procedural steps. For this purpose, the apical end of the mounting part is shaped in order to adapt the external cross-section of the mounting part to the internal cross-section of the post part.12-02-2010
20110053109ORTHODONTIC ANCHORING SCREW - A fixing wire, in particular for applying treatment forces to a tooth, is intended to be protected in an extremely simple manner against translatory and rotational displacements and against being dislodged, with the mounting and dismantling time kept short. For this purpose, the fixing wire has a widened region produced by plastic deformation, for the longitudinal fixing thereof in a corresponding fixing recess of an orthodontic anchoring screw.03-03-2011
