The implant (5) has an anchoring part (10) for anchorage in bone, and a structural component (15) for receiving a to-be-applied element e.g. abutment. The structural component has a core and a covering layer that are visually and/or acoustically different from each other. The implant is formed as a one-piece part. An intermediate layer is arranged between the core and the covering layer, and is visually and/or acoustically different from the core and the covering layer. The core contains a dye comprising metallic copper nanoparticles. An independent claim is also included for a method for manufacturing a one-piece dental implant.
