Ways of carrying out the invention

In the following, objects, features and advantages of the present invention will become more apparent from the detailed description of embodiments and the accompanying drawings. However, the invention should not be limited to the description and the accompanying drawings.

According to the first preferred embodiment in FIG 1 and 2 The auxiliary device according to the invention, which cooperates with a guide model for tooth implantation, comprises a positioning element 10 , an anchor ring 20 and a pulling element 30 ,

As in 1 . 3 and 4 shown, includes the positioning element 10 a ring bearer part 11 and a positioning part 12 , wherein the ring carrier part 11 is provided with a center axis line C1, wherein the positioning part 12 and the ring bearer part 11 are firmly connected to each other, wherein on the outside of the positioning member 12 a first and a second positioning surface 121 . 122 are arranged, which are each formed as a vertical plane and respectively the central axis line C1 of the ring carrier part 11 comprising, wherein the first and the second positioning surface 121 . 122 perpendicular to each other.

Preferably, the ring carrier part comprises 11 on the positioning part 12 fixed base piece 111 and one at the base piece 111 attached pole 112 ; the base piece 111 is cylindrical in shape; the pole 112 is with a rotary section 1121 and an easily breakable section 1122 provided, wherein the rotary section 1121 at the base piece 111 is fixed and has a round cross-section; the easily breakable section 1122 is with the rotary section 1121 connected and the base piece 111 facing away, with the easily breakable section 1122 has a rectangular cross-section.

As in 2 . 5 and 6 shown, the anchor ring points 20 a leadership hole 21 that is through the anchor ring 20 passes through, with the anchor ring 20 with the leadership hole 21 on the rotary section 1121 of the ring bearer part 11 is placed, wherein the Mittelachslinien C2, C1 of the guide hole 21 and the ring bearer part 11 on the same straight line. The leadership hole 21 has a round cross-section. The anchor ring 20 is rotatable on the rotary section 1121 placed.

Preferably, on the outer peripheral surface of the anchor ring 20 a stamping surface 22 arranged; on the inner wall of the guide hole 21 is a plurality of spaced water drainage troughs 23 arranged parallel to the central axis line C2 of the guide hole 21 through the two opposite end faces of the guide hole 21 pass through, preferably three Wasserableitrinnen 23 are provided.

How out 4 and 5 can be seen, is the drawing element 30 separable on the easily breakable section 1122 fitted and with a receiving opening 31 and two drawing surfaces 32 provided, wherein the receiving opening 31 on the easily breakable section 1122 is attached and has a rectangular cross section, wherein the two drawing surfaces 32 each on two opposite sides of the outer peripheral surface of the drawing element 3 are located and each executed as a vertical plane.

For the implantation of a tooth, a tooth model T is first manufactured in accordance with the teeth of the patient, wherein at the location of the missing tooth, at which point a tooth is implanted, the tooth model T is cut vertically, so that a longitudinal section T1 results. 7 shows a side view of the cut-through tooth model T.

Subsequently, a positioning line L is drawn on the longitudinal section T1 with a pencil, which represents the point at which the tooth is implanted.

Thereafter, the first positioning surface 121 Adhesive applied and then adhered to the longitudinal section T1. The auxiliary device becomes the left side of the 7 moved until the second positioning surface 122 aligned with the positioning line L.

Once the auxiliary device according to the invention is stably glued to the longitudinal section T1, the position of the anchor ring 20 fixes which position represents the location of the tooth to be implanted. Here is the X-coordinate of the anchor ring 20 when applying the first positioning surface to the longitudinal section T1 and the Y-coordinate of the anchor ring 20 when aligning the second positioning surface 122 having already been positioned with the positioning line L, the X and Y coordinates both being adjustable by the dentist himself; For example, the location for cutting the tooth model T and the location of the positioning line L can be changed.

As in 8th 2, the gelatinous guide model for the operation Q is applied to the tooth model T and the auxiliary device according to the invention. Once the leadership model for Operation Q becomes hard and solid, the anchor ring is 20 with the leadership model for the operation Q firmly connected. 8th shows a side view of the auxiliary device according to the invention, which is glued to the guide model for the operation Q. The anchor ring 20 attached embossing surface 22 ensures a greater frictional force between the anchor ring 20 and the guide model for the operation Q, to release the anchor ring 20 from the leadership model for Operation Q.

As in 9 shown, the dentist puts his finger on the drawing surface 32 and pulls the pulling element 30 such that the easily breakable section 1122 is canceled; after that, the positioning element 10 away; This will be an in 10 shown leadership model for the operation Q with an associated anchor ring 20 receive. Because the receiving opening 31 and the easily breakable section 1122 are rectangular in cross-section, they do not rotate relative to each other, which is the positioning of the drawing element 30 facilitates and canceling the easily breakable section 1122 of the pulling element 30 favored.

When performing a dental implantation, the manufactured guide model for surgery Q is placed on the teeth, now the location of the anchor ring 20 represents the location of the tooth to be implanted. Subsequently, the dentist performs a drill bit specific for tooth implantation through the guide hole 21 of the anchor ring 20 through to carry out the further steps of tooth implantation. Because the anchor ring 20 can be accurately positioned after the intended implantation site, the dentist can avoid mistakes during dental implantation.

When drilling in alveolar bone during dental implantation, a high temperature is produced by which cells will die; To reduce the temperature, a large amount of water is introduced, with the anchor ring 20 arranged Wasserableitrinnen 23 serve to drain the water.

As in 11 2, the preferred second embodiment is substantially identical to the first, but differs from the first in that additionally an auxiliary mount 40A is provided, which with a contact surface 41A and a socket 42A is provided, wherein the contact surface 41A as one on the outside of the auxiliary mount 40A vertical level is executed and on the upper side with the first positioning surface 121A Aligns with the socket 42A at the contact surface 41A located and profile with the positioning part 12A matches, with the positioning part 12A separable in the socket 42A is arranged sticking.

For the handling of the second preferred embodiment is on 12 directed. The auxiliary device is glued to the longitudinal section T1 and then moved, the anchor ring 20A and the auxiliary bracket 40A Finally, both are glued to the longitudinal section T1. The following steps are substantially identical to those of the first preferred embodiment, the difference being that the auxiliary mount 40A adhered to the longitudinal section T1 and is not removed. This has the advantage that when needed to manufacture a new leadership model for the operation Q with leadership hole 21 another dimension only a new positioning element 10A , an anchor ring 20A another dimension and a drawing element 30A on the auxiliary bracket 40A need to be mounted, whereby the guide model for the operation Q can be made quickly.

Because the auxiliary bracket 40A previously adhered and positioned at the site for the dental implantation, the dentist merely needs the new positioning element 10A in the auxiliary bracket 40A plug in, without the positioning element 10A to postpone for the purpose of positioning again, whereby the amount of time can be significantly reduced and the work is facilitated.

It has to be explained that in dental implants, drill bits of various sizes can be required, due to which anchor rings 20A with leadership hole 21 different dimensions may be required. Therefore, if necessary, a new leadership model for the operation Q with leadership hole 21 different sizes are manufactured.
