  • Publication number: 20140162215
    Abstract: An abutment is provided which enables an associated anchoring part to be introduced into a bone without the anchoring part being damaged. A corresponding abutment includes: an abutment upper part disposed along a longitudinal axis and an abutment lower part. For form-fitting insertion of the abutment into an abutment receiving region of an anchoring part, the abutment lower part has a profile such that a torque applied to the abutment is transferable to the anchoring part. The abutment upper part includes a tool receiving portion for form-fittingly receiving a tool.

  • Patent number: 8740616
    Abstract: A dental implant system includes a base member that is adapted to be embedded within a patient's jawbone at a treatment site. The base member has a generally flat top defining an outer periphery, a buccal side, a lingual side, a bottom, and a central opening. The lingual side or the buccal side is longer than the other. The base member is configured to be positioned within a recess in the patient's jawbone. An implant screw includes a head and a threaded end. The threaded end is adapted to pass through the central opening of the base member and into the patient's jawbone, and the head is adapted to be seated within the central opening of the base member after the threaded end is screwed into the patient's jawbone. An abutment is configured to be placed onto the top of the base member.

  • Patent number: 8734889
    Abstract: The invention relates to a ceramic implant, especially a dental implant, comprising a structured or porous surface for at least partially inserting into a bone. An especially advantageous surface is obtained when it is at least partially modified by a salt melt. These excellent osteointegration properties can be obtained by a method whereby the surface is modified in a salt melt at least in the regions exposed to the bones and/or soft tissue, optionally following a previous modification of the surface whereby material has been removed.

The method comprises the act of roughening at least a portion of the implant surface to form a roughened surface. The method further comprises the act of, without forming an alkoxide on the roughened surface, depositing nanocrystals on the roughened surface. The nanocrystals comprise a material having a property that promotes osseointegration.

  • Publication number: 20130344458
    Abstract: The present invention concerns a method for inserting a dental implant into the jawbone as a replacement for a tooth, said jawbone comprising cortical bone matter surrounding a core of spongy bone, wherein a hole is excavated in the cortical bone of the upper surface of the jawbone using an excavation tool, said hole penetrating mainly the cortical bone matter of the jawbone. The excavation tool is then removed and a threaded implant is placed in the excavated hole of the upper surface of the jawbone; the threaded implant is forwarded into the spongy bone core of the jawbone without any prior drilling having been done into the spongy bone section of the jawbone; and the implant is left in the spongy bone core of the jawbone for promoting integration of the implant with the surrounding bone (Osteointegration).

  • Publication number: 20130344459
    Abstract: A modular implant includes a head, an intermediate part configured to engage bone, and an initially separate anchor configured to engage the head so that at least the head and the anchor cooperatively secure the intermediate part on the implant to form the modular implant. At least one of the head, the intermediate part, and the anchor has a plurality of forms, and each form is configured to be assembled on at least one form of the other two of the head, intermediate part, and anchor. The intermediate part may include a porous metal such as tantalum.

  • Publication number: 20130337408
    Abstract: The invention provides dental implants for fixed and removable prosthetic devices, and for other devices such as orthodontic devices, and has application to single tooth replacement, e.g., caps and crowns, and multiple tooth replacement using one or more implants, e.g., bridges, and multiple implants for full and partial prosthetic devices. Dental implants according to embodiments of the invention comprise a post or posts inserted into the jawbone and a base that is loaded, in the general area of the gum line, against the jawbone using the post or posts. According to some embodiments, the base is secured to each post, loaded against the jawbone, by a fastener system.

  • Publication number: 20130337410
    Abstract: The invention relates to an intra-osseous implant for placement in bone of a human or animal body comprising at least one intra-osseous part intended for placement in said bone tissue having an apical side and a cervical side and composed of a body friendly material, which part is provided on its circumferential surface with a thread running in the direction of the apical end; and a support part present at said cervical side of said at least one intra-osseous part intended for supporting a prosthetic element. The invention aims to provide a medical intra-osseous implant and especially a dental intra-osseous implant, which allows an accurate implant position at a desired depth into bone tissue, providing without losing a high degree of primary implant stability.

  • Patent number: 8608473
    Abstract: An immediate provisional implant is provided, and method of use therefor, that serves to protect permanent dental implant anchors and overlying tissue during the healing and osseointegration process. Potentially damaging forces resulting from patient use of a temporary prosthesis during the osseointegration period are carried by the immediate provisional implant, rather than impinging upon non-osseointegrated permanent implant anchors or overlying tissue. The immediate provisional implants are self-threading and are inserted in osteotomies located near permanent dental implant anchors. The temporary prosthesis is removed after a period allowed for osseointegration of the permanent implant anchors, and the provisional implants can also be removed at the same time. The immediate provisional implants are non-linearly tapered from a maximum thread diameter near the bone surface to a more narrow distal end, providing immediate stability without the benefit of osseointegration.

  • Patent number: 8602781
    Abstract: A dental implant device for insertion into bone includes an implant anchor having an interlocking thread helically defined around a longitudinal axis, the thread being adapted to couple to a female threaded portion in a bone. The interlocking thread has a first superior contact surface having a first angle relative to the longitudinal axis, a second superior contact surface extending radially outward from the first contact surface and having a second angle relative to the axis, and an inferior flank surface having a third angle relative to the axis. The first angle is larger than the second angle such that the first contact surface and the second contact surface form an approximate ā€œVā€ or chevron shape in a cross-sectional view. The first angle is larger than the third angle.

  • Patent number: RE44800
    Abstract: Dental implant (10) for rotation into the bone tissue of a jaw bone consisting of a body having an axis of rotation, a coronal end surface (5), an apical end surface (1) and a generally cylindrical section (7) which has a coronal edge coincident with, or in close proximity to, the coronal end surface and an outer peripheral surface which extends apically towards the apical end surface from the coronal edge. The outer peripheral surface is presented by a circumferentially-oriented roughness (19) comprising a series of circumferentially-oriented peaks which are axially spaced apart by troughs and oriented at an inclined angle to the axis of rotation. The height from the troughs to the peaks throughout the circumferentially-oriented roughness is greater than 0.2 mm.
