The core (1) is made of a hard foam and has the same chemical composition as the basic body (6). To the core plastic foam is added an X=ray contrast medium. A nerve channel running through the bone is marked with an X=ray contrast medium. An X=ray opaque thread (22) represents a nerve (21) running in or on the bone. A cover of silicon at least partly encloses the basic body and represents a mucous membrane at least partly surrounding the bone. A rubber layer on an inner surface of a recess in the basic body represents a bone hollow mucous membrane, particularly a jaw hollow mucous membrane. |
