A method and apparatus for treating snoring include selecting an implant formed of a bio-compatible material having dimensions including a longitudinal length, a thickness and a width. The material is sized to be inserted into the soft palate with the longitudinal length extending aligned with an anterior-posterior axis of the palate and with the thickness contained within a thickness of the soft palate. The implant includes a tissue growth-inducing material having a plurality of spaces for accepting tissue growth from the soft palate into the spaces. The material is contractible in at least one of the dimensions in response to implantation of the implant in a body tissue.
