The implant (1) has a distal portion (3) dimensioned for completely accommodating in a soft palate (32), where the implant is in an inserted form, brought into an inserted form, or made of a shape memory material. A proximal portion (2) is dimensioned for fixing to a hard palate (31) and a middle portion (4) extending between the proximal portion and the distal portion. The distal portion is arranged at an angle in relation to the proximal portion, and in a sectional plane extending through the proximal portion and the distal portion. An independent claim is also included for a selection process for selecting an implant from a set of implants.
