Abstract

The invention relates to an implant for a palate, in particular a human palate. The implant comprises a proximal portion, a distal portion and a middle portion. The proximal portion is dimensioned in such a way that it can be fixed to a hard palate. The distal portion is arranged at an angle in relation to the proximal portion and is dimensioned in such a way that it can be accommodated completely in a soft palate. The middle portion extends between the proximal portion and the distal portion. In a sectional plane extending through the proximal portion and the distal portion, the curvature of the middle portion at each of its points is greater than the curvature of the proximal portion at each of its points and greater than the curvature of the distal portion at each of its points.

Claims

1. An implant adapted for use in a palate, in particular a human palate, said implant comprising

a distal portion dimensioned so as to be completely accommodated in a soft palate, and

a proximal portion dimensioned so as to be fixed to a hard palate, and

a middle portion extending between the proximal portion and the distal portion,

wherein the implant is elastic in the middle portion in such a way that the distal portion is resilient in relation to the proximal portion, and

the proximal portion extends at an angle of between 15°

and 75°

in relation to the distal portion.

2. The implant as claimed in claim 1, wherein the middle portion has an intended deformation region, at which the middle portion can be deformed.

3. The implant as claimed in claim 1, wherein at least part of the implant has an ingrowth structure for the growing in of body tissue.

4. The implant as claimed in claim 1, wherein the implant comprises a shape memory material or consists thereof, and at an inserted temperature of between 35°

C. and 40°

C. is in the inserted form.

5. The implant as claimed in claim 1, further comprising means for connecting the implant to the hard palate.

6. The implant as claimed in claim 1, wherein the implant comprises or consists of plastic.

7. The implant as claimed in claim 1, wherein the implant is substantially in the form of a strip.

8. The implant as claimed in claim 1, wherein the proximal portion has a length (l₁) of 15 mm to 30 mm.

9. The implant as claimed in claim 1, wherein the distal portion has a length (l₂) of 15 mm to 25 mm.

10. A set of implants comprising at least two implants, wherein a first implant of said implants and a second implant of said implants are each according to claim 1, the second implant being different from the first implant.

11. A set of implants including at least two implants, wherein at least one implant of said implants is according to claim 1, as well as at least one insertion device for inserting the implant.

12. A set of implants including at least two implants, wherein at least one implant of said implants is according to claim 1, as well as at least one sizer for estimating the size of an implant to be inserted.

13. The implant as claimed in claim 1, wherein the implant comprises a metal.

14. The implant as claimed in claim 1, wherein the implant has an inner metal core and an outer plastic shell.

15. A method for selecting, from a set of different implants, an implant adapted for use in a palate, in particular a human palate, each said implant comprising

a distal portion dimensioned so as to be completely accommodated in a soft palate, and

a proximal portion, dimensioned so as to be fixed to a hard palate, and

a middle portion extending between the proximal portion and the distal portion,

wherein the implant is elastic in the middle portion in such a way that the distal portion is resilient in relation to the proximal portion,

which method comprises the following steps:

a) establishing the condition of the hard palate and the soft palate of a patient; and

b) selecting an implant in dependence on the finding established in step a).
