Abstract

Abstract A method for applying a direction-adjusting extension piece in a dental implant includes the steps of screwing an orientation axle, provided with marks, in an implant; determining the required axis adjustment; screwing the orientation axle out of the implant, and screwing in an appropriate extension piece, with the determined necessary axis correction. The invention is also directed to the various components used in this method.

Claims Analysis

Total Claims: 20
Claim 1
Independent Claim 117 words
An arrangement for correcting an orientation axis associated with a dental implant comprising: an orientation axle including a screw thread part and a body, said body being provided, at least at an upper extension portion thereof, with a plurality of circumferentially spaced marks; and a series of extension pieces each of which has an associated direction-adjusting element that defines a predetermined mounting axis corresponding to a respective one of said plurality of marks, whereby said orientation axle may be placed within a dental implant to determine a required adjustment of an orientation axis associated with the implant and a respective one of said extension pieces can be selected based on the presence of said plurality of marks.
Claim 2
Dependent Claim 117 words
An arrangement for correcting an orientation axis associated with a dental implant comprising: an orientation axle including a screw thread part and a body, said body being provided, at least at an upper extension portion thereof, with a plurality of circumferentially spaced marks; and a series of extension pieces each of which has an associated direction-adjusting element that defines a predetermined mounting axis corresponding to a respective one of said plurality of marks, whereby said orientation axle may be placed within a dental implant to determine a required adjustment of an orientation axis associated with the implant and a respective one of said extension pieces can be selected based on the presence of said plurality of marks.
Claim 3
Dependent Claim 25 words
An arrangement according to claim 1, wherein said screw thread part is adapted to be threadably received within an internal screw thread of an implant.
Claim 4
Dependent Claim 16 words
An arrangement according to claim 1, wherein the marks continue about the circumference of the body.
Claim 5
Dependent Claim 14 words
An arrangement according to claim 1, wherein each mark is formed by a stripe.
Claim 6
Dependent Claim 14 words
An arrangement according to claim 1, wherein each mark has an associated identification element.
Claim 7
Dependent Claim 33 words
An arrangement according to claim 1, wherein each of said direction-adjusting extension pieces comprises a head, which forms an extension of a screw thread part, and a direction-adjusting part connected to said head.
Claim 8
Dependent Claim 33 words
An arrangement according to claim 6, wherein said direction-adjusting part is provided with a screw thread hole which is placed at an angle in relation to a longitudinal axis of the extension piece.
Claim 9
Dependent Claim 20 words
An arrangement according to claim 7, wherein the direction-adjusting part is connected to the head thereof by means of gluing.
Claim 10
Dependent Claim 22 words
An arrangement according to claim 7, wherein the direction-adjusting part is connected to the head thereof by means of soldering or welding.
Claim 11
Dependent Claim 66 words
An arrangement according to claim 7, further comprising a tooth, which is to be connected to the extension piece, mounted on a hollow support in which, after mounting, a filling is applied, said hollow support having an aslant bottom, whereby through the hollow support, a screw can be applied for mounting the tooth to the extension piece by threading the screw into said screw thread hole.
Claim 12
Dependent Claim 80 words
An arrangement according to claim 7, further comprising a tooth, which is to be connected to the extension piece, mounted on a hollow support in which, after mounting, a filling is applied, said hollow support having a bottom that is at a right angle to a longitudinal axis of said hollow support, whereby through the hollow support, a screw can be applied for mounting the tooth to the extension piece by threading the screw into said screw thread hole thereof.
Claim 13
Dependent Claim 62 words
An arrangement according to claim 6, wherein said direction-adjusting part is provided with a screw thread hole which is placed at an angle in relation to a longitudinal axis associated with the extension piece, whereby an upper wall of the direction-adjusting part defines a plane which is aslant and whereby this plane is directed at right angles to the screw thread hole.
Claim 14
Dependent Claim 26 words
An arrangement according to claim 6, wherein an upper wall and the direction-adjusting part is at right angles to a longitudinal axis of the extension piece.
Claim 15
Dependent Claim 32 words
An arrangement according to claim 6, wherein said direction-adjusting part is formed by a conical axle which is placed at an angle in relation to a longitudinal axis of the extension piece.
Claim 16
Dependent Claim 73 words
An arrangement according to claim 1, further comprising a tooth which is adapted to be connected to the extension piece, said tooth being mounted on a hollow support in which, at a top thereof, a filling is applied, whereby said hollow support has an aslant bottom and is provided with a conical hole that is adapted to be clenched onto a conical axle in order to connect the tooth to the extension piece.
Claim 17
Dependent Claim 59 words
An arrangement according to claim 1, further comprising a tooth which is adapted to be connected to the extension piece, said tooth being mounted on a hollow support in which, at a top thereof, a filling is applied, whereby said hollow support terminates, at a onto a conical axis in order to connect the tooth to the extension piece.
Claim 18
Independent Claim 91 words
A method for applying a direction-adjusting extension piece in a dental implant in order to correct an orientation axis associated with the implant comprising: screwing an orientation axle, provided with various circumferentially spaced marks, in an implant having an associate axis oriented in a certain manner; determining a required axis adjustment corresponding to one of said marks; screwing said orientation axle out of the implant; and screwing in one of a series of extension pieces which correspond to said one of said marks so as to provide the necessary axis correction.
Claim 19
Independent Claim 91 words
A method for applying a direction-adjusting extension piece in a dental implant in order to correct an orientation axis associated with the implant comprising: screwing an orientation axle, provided with various circumferentially spaced marks, in an implant having an associate axis oriented in a certain manner; determining a required axis adjustment corresponding to one of said marks; screwing said orientation axle out of the implant; and screwing in one of a series of extension pieces which correspond to said one of said marks so as to provide the necessary axis correction.
Claim 20
Dependent Claim 131 words
A method according to claim 17, further comprising constructing each of said extension pieces by starting from an orientation axle which is screwed completely in a screw thread hole of a mother matrix; transferring marks provided on this mother matrix to this orientation axle; screwing the thus completed orientation axle out; screwing a head portion of a direction-adjusting extension piece completely in the same screw thread hole of the same mother matrix; connecting a direction-adjusting part of the extension piece to said head in such a way that a mark on the direction-adjusting part is placed opposite to a corresponding mark of the mother matrix; and repeating this process to form the series of extension pieces such that for each mark of the orientation axle, a different extension piece is obtained.
