Publication number: 20130344458Abstract: 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).Type: ApplicationFiled: May 9, 2011Publication date: December 26, 2013Inventor: Mohamad Saeed Taha

Publication number: 20130344459Abstract: 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.Type: ApplicationFiled: August 27, 2013Publication date: December 26, 2013Applicant: Zimmer Dental, Inc.Inventors: Michael Scott Collins, Harold C.

Publication number: 20130337408Abstract: 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.Type: ApplicationFiled: May 17, 2013Publication date: December 19, 2013Applicant: CH Scientific, LLCInventor: Curtis W. Adams

Publication number: 20130337410Abstract: 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.Type: ApplicationFiled: June 27, 2013Publication date: December 19, 2013Applicant: Ten Bruggenkate Kaakchirugie B.V.Inventor: Christiaan Michiel TEN BRUGGENKATE

Publication number: 20130337409Abstract: The present disclopsure relates to an implant, such as a dental implant, having a base member and a thread arranged at an outer end of the base member. The dental implant can be easily inserted and good footing of the implant in the bone can be achieved. Annular ridges and/or recesses can be formed in a section of the base member having no thread.Type: ApplicationFiled: June 12, 2013Publication date: December 19, 2013Inventor: Thorsten BUURLAGE

Patent number: 8608473Abstract: 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.Type: GrantFiled: October 22, 2003Date of Patent: December 17, 2013Assignee: Nobel Biocare USA, Inc.Inventor: Don Kennard

Patent number: 8602782Abstract: An implant device has an exterior portion forming an exterior surface of the implant. The exterior portion is made of a porous material defining passages through the exterior portion. An inner portion has an outer surface with a treated area that is accessible from the exterior surface through the passages. The treated area has a treatment for direct attachment to bone or soft tissue.Type: GrantFiled: November 24, 2009Date of Patent: December 10, 2013Assignee: Zimmer Dental, Inc.Inventor: Matthew Lomicka

Patent number: RE44800Abstract: 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.Type: GrantFiled: April 24, 2003Date of Patent: March 11, 2014Assignee: Astrazeneca ABInventor: Stig Hansson
