Patent ID: 8777613

Claim:
An implant arrangement for inserting in a jaw a dental implant having a given diameter, comprising a splint having a bore therethrough and being shaped to be received over at least a portion of the jaw with the bore substantially axially aligned with a site on the jaw into which said implant is to be inserted, a guide sleeve arranged within the bore, an annular guide surface formed within a placement sleeve received in the guide sleeve, the guide surface being of greater diameter than a maximum diameter of said implant, an insertion tool for screwing in the implant into the jaw and having a head for connection to said implant so as to connect the insertion tool and implant together, the head having an annular exterior surface of smaller diameter than said guide surface for sliding engagement with the guide surface, the insertion tool having a first stop surface being formed by a surface of the head of the insertion tool, a second stop surface being formed within the placement sleeve received in the bore in a plane substantially orthogonal to an axis of the bore, the first and second stop surfaces being located so as to abut against each other when said implant has been inserted by the insertion tool to a predetermined depth in the jaw so that said abutment defines an insertion depth of the implant, and in which a bore sleeve is received in the bore for guiding a drill and a drill bit to a predetermined bore depth as the drill bit drills the jaw in preparation for insertion of said implant, the bore sleeve being received in the guide sleeve and the bore sleeve and the guide sleeve comprising respectively corresponding radially disposed exterior and interior stepped positioning elements formed thereon that engage with each other to alignably position the bore sleeve in the guide sleeve and in the bore in an axial direction of the bore along a longitudinal axis of the bore, the bore sleeve comprising a drill positioning stop surface distal an outermost top peripheral surface of the splint and against which a surface of the drill abuts prior to the bore sleeve being removed from the guide sleeve upon completion of drilling of the jaw, and in which upon removal of the bore sleeve, a stepped positioning element of the placement sleeve corresponding to said stepped positioning element of the guide sleeve engage with each other so as to axially align and seat said second stop surface of the placement sleeve during insertion of the implant, and each of the above stepped positioning elements comprising, when viewed in cross-section, a laterally and vertically extending portion relative to the longitudinal axis of the bore that engage each other upon engagement of the bore sleeve and the placement sleeve with the guide sleeve, said engagement of the respective sleeves at the respective laterally and vertically extending portions comprising one or more points of engagement located substantially beneath an outermost top peripheral surface of each of the respective sleeves and the outermost top peripheral surface of the splint.
