Definitions
- An implant device is known from CH 684 384 A5, in which such a cylindrical, rotationally symmetrical body can be inserted as an implant into a jawbone.
- a threaded blind hole is provided in the end facing away from the jaw bone, the central axis of which coincides with the central axis of the implant shaft.
- a holding device can be screwed into the threaded blind hole, the central axis of which coincides with the central axis of the threaded blind hole.
- An artificial denture can be attached to the holding device, the crown axis of which should coincide with the central axis of the holding device and the threaded blind hole.
- the placement of the implant must be based on the available bone in the upper or lower jaw. Therefore, there are often divergences between the implant axis, the middle axis of the implant shaft and the prosthetically necessary crown axis. In the implant device known above, this axis divergence can be compensated for by individual additional parts applied to the straight implant shaft.
- the screwed-in insertion tool makes the angled implant device rotationally symmetrical and can also be inserted into narrow single tooth gaps without requiring additional space.
- the figure shows the implant device according to an embodiment of the present invention.
- the implant device 1 has an implant shaft 2, an insertion tool 3 and a screw 4.
- the implant shaft 2 which forms the actual implant in the state inserted in the jawbone (not shown), is provided with an external thread 5.
- the central axis 6 of the implant shaft 2 is concentric with the external thread 5
- the protrusion 7 protrudes from an upper surface 8 of the head.
- the projection 7 and the upper surface 8 form a shoulder.
- the axis perpendicular to the upper surface 8 is inclined relative to the central axis 6 of the implant shaft by a predetermined angle, for example by 20 °.
- the central axis of the projection 7 is also inclined by the predetermined angle with respect to the central axis 6 of the implant shaft 2.
- a threaded blind hole 9 is formed in the projection 7.
- the central axis 10 of the threaded blind hole 9 coincides with the central axis of the projection 7.
- the predetermined angle between the central axis 6 of the implant shaft 2 and the central axis 10 of the threaded blind hole 9 or the central axis of the projection 7 corresponds to the angle at which the implant can be inserted into the jawbone, so that the central axis 10 of the threaded blind hole 9 or the central axis of the projection 7 coincides with the crown axis of the dental prosthesis to be attached (not shown) despite insufficient bone supply.
- the insertion tool 3 of the implant device 1 has an essentially cylindrical shaft 11.
- the insertion tool 3 has at one end a recess 12 which has an internal octagon shape such that the recess 12 can be fitted onto the projection 7 in a snug fit.
- the central axis of the recess 12 is inclined relative to the central axis 13 of the cylindrical shaft of the insertion tool by the same angle as the central axis 10 of the blind hole 9 of the implant shaft 2.
- a first bore 12 extends from a circumference of the cylindrical shaft 11 to just before the recess 12.
- a central axis 15 of the first bore 14 is inclined by the same angle with respect to the central axis 13 of the cylindrical shaft 11 of the insertion tool 3 how the central axis 10 of the threaded pocket hole 9 of the implant shaft 2.
- a handle 16 is attached to the insert tool 3 at the end opposite the end with the recess 12.
- a second bore 14 is provided so that a hole 17 is formed, the diameter of which is smaller than the general diameter of the first bore 14.
- the screw 4 of the implant device 1 is dimensioned such that the screw 4 can be screwed into the threaded blind hole 9.
- the inside diameter of the hole 17 is dimensioned such that the threaded shaft of the screw 4 passes through the hole 17.
- the diameter of the head of the screw 4 is dimensioned such that it does not fit through the hole 17 of the first bore 14.
- the implant device is used as follows.
- a drill shaft is drilled in the jawbone at the point where the denture is to be attached.
- the direction of the shaft depends on the available bone in the upper or lower jaw.
- the diameter of the shaft is chosen to be somewhat smaller than the diameter of the implant shaft 2.
- An internal thread is cut into the shaft, which is selected to be somewhat smaller than the external thread 5 of the implant shaft 2.
- the depth of the shaft is chosen one thread stroke deeper than the length of the implant shaft 2.
- the insertion tool 3 is placed on the implant shaft 2 such that the central axis 6 of the implant shaft 2 coincides with the central axis 13 of the insertion tool 3.
- the central axis 10 of the threaded blind hole 9 and the central axis 15 of the first bore 14 coincide.
- the screw 4 is inserted through the first bore 14 into the insertion tool, inserted through the hole 17 and screwed into the threaded blind hole 9 such that the insertion tool 3 is firmly connected to the implant shaft 2.
- the implant shaft 2 is screwed into the shaft drilled in the jaw bone by turning the insertion tool 3.
- the final rotational position of the implant shaft 2 is chosen so that the orientation of the first bore 14, which is visible, points in the direction which coincides with the crown axis of the dental prosthesis to be applied. It is therefore important to prepare the drill shaft in the jawbone about 1 mm deeper than the implant shaft is long, so that if the thread pitch is 1 mm, any unsuitable rotational position can be corrected by turning it in deeper.
- the screw 4 is loosened so that the insertion tool 3 can be removed from the implant shaft 2.
- the crown axis lies in the desired direction, namely in the direction that the axis of the replaced tooth has.
- the implant shaft 2 is arranged in a direction in the jaw bone which is predetermined by the existing bone material.
- the central axis of the implant shaft 2 therefore does not necessarily lie in the extension of the crown axis.
