Abstract

Claims (25)

1 . A maxilla repositioning implant for three-dimensional precise orienting of a maxilla displacing portion relative to a remaining maxilla portion fixed to the skull, wherein the maxilla repositioning implant comprises:

a base having at least one base plate in which base plate screw holes are provided, wherein each base plate screw hole is defined by a base plate screw hole rim formed from a portion of the material of the base plate and configured for receiving an external bone screw that fastens the base to a remaining maxilla portion fixed to a skull, the at least one base plate including a first base plate; and

a connection portion spaced from the base via connecting bridges including a first connecting bridge and a second connecting bridge, wherein the connection portion has at least one connection plate in which connection plate screw holes are provided, and wherein each connection plate screw hole is defined by a connection plate screw hole rim formed from a portion of the material of the connection plate and configured for receiving an external bone screw that fastens the connection portion to a maxilla displacing portion, the at least one connection plate including a first connection plate;

wherein the first base plate and the first connecting plate are coupled by the first and second connecting bridges that extend from the first connection plate towards the base plate screw hole rim of the first base plate;

wherein the first base plate, the first and second connecting bridges and the first connecting plate are components of a stable three-dimensional structure in which the first base plate is not coplanar with the first connecting plate; and

wherein the maxilla repositioning implant is suitable for providing precise three-dimensional orientation of the maxilla displacing portion relative to the remaining maxilla portion.

2 . The maxilla repositioning implant according to claim 1 , wherein the connecting bridges have an elliptical cross-section.

3 . The maxilla repositioning implant according to claim 2 , wherein the elliptical cross-section assumes the specific shape of a circle.

4 . The maxilla repositioning implant according to claim 1 , wherein at least one of the plate of the base and the plate of the connection portion has at least one point which has a greater thickness than the connecting bridges.

5 . The maxilla repositioning implant according to claim 1 , wherein each plate of the base and each plate of the connection portion are connected to each other via two connecting bridges.

6 . The maxilla repositioning implant according to claim 1 , wherein the connecting bridges run parallel to each other over a majority of their respective lengths.

7 . The maxilla repositioning implant according to claim 1 , wherein each connecting bridge has a first end and a second end, wherein the first end transitions as a single piece of material into the base plate screw hole rim and the second end transitions as a single piece of material into the connection plate screw hole rim.

8 . The maxilla repositioning implant according to claim 1 , wherein the first connecting bridge and the second connecting bridge engage with their first ends on the base plate screw hole rim and a) either engage with their second ends together at the connection plate screw hole rim, or b) the first connecting bridge engages with its second end at a first base plate screw hole rim of the connection portion and the second connecting bridge engages at a second base plate screw hole rim of the connection portion.

9 . The maxilla repositioning implant according to claim 8 , wherein the second connecting bridge progressively increases in distance away from the first connecting bridge over the length as seen from the base plate.

10 . The maxilla repositioning implant according to claim 1 , wherein each of the at least one base plate and the at least one connection plate has two or more screw holes.

11 . The maxilla repositioning implant according to claim 1 , wherein the maxilla repositioning implant is formed as the stable three-dimensional structure during manufacturing to conform to a patient-specific surface contour of a patient's maxilla.

12 . The maxilla repositioning implant according to claim 1 wherein a sintering process is used to form the maxilla repositioning implant as the stable three-dimensional structure.

13 . The maxilla repositioning implant according to claim 1 , wherein the first and second connecting bridges each include a straight portion and at least one arced portion that cooperate to hold the first connecting plate in the non-coplanar orientation relative to the base plate.

14 . The maxilla repositioning implant according to claim 1 , wherein the connecting bridges define a planar offset between the base and the connection portion.

15 . A maxilla repositioning implant for three-dimensional precise orienting of a maxilla displacing portion relative to a remaining maxilla portion fixed to the skull, the maxilla repositioning implant comprising:

a base having at least one base plate in which base plate screw holes are provided, wherein each base plate screw hole is defined by a base plate screw hole rim formed from a portion of the material of the base plate and configured for receiving an external bone screw that fastens the base to the remaining maxilla portion fixed to the skull, the at least one base plate including a first base plate; and

a connection portion spaced from the base via rigid connecting bridges including a first connecting bridge and a second connecting bridge, wherein the connection portion has at least one connection plate in which connection plate screw holes are provided, and wherein each connection plate screw hole is defined by a connection plate screw hole rim formed from a portion of the material of the connection plate and configured for receiving an external bone screw that fastens the connection portion to the maxilla displacing portion, the at least one connection plate including a first connection plate;

wherein the rigid connecting bridges extend from the at least one connection plate towards the base plate screw hole rim of the at least one base plate and maintain a three-dimensional relationship between the connection portion and the base;

wherein the first base plate, the first and second connecting bridges and the first connecting plate are components of a stable three-dimensional structure in which the first base plate is not coplanar with the first connecting plate; and

wherein the maxilla repositioning implant is suitable for providing precise three-dimensional orientation of the maxilla displacing portion relative to the remaining maxilla portion.
