Two or more implants (8, 9, 10) are arranged in succession in the jaw bone (1) and bear or comprise growth-stimulating substances (25), here called GSS, which, as a function of secretion of body fluid at the implants, are intended to be released and form new bone (11-15) around the implants. The implants are designed to work with a release process for GSS, permitting a leveling-out effect along the extent of the jaw bone in the horizontal and/or vertical direction and/or a level-raising effect in the vertical direction. In this way it is possible to achieve optimum positions for the implants without the risk of reduced stability and/or compromised esthetics.
