Abstract: A bridge for an artificial dental structure is made of titanium. The bridge is constructed from modular elements which are adapted one to the other and are treated for joining together, for example by means of laser welding. In a first treatment unit one or more first treatment stages are performed for the construction of the bridge. Identification data introduced or utilized in this or these stages relating to the individual different heights of the anchorage elements above the dentine and their different relative inclinations, and the positions and directions of the modular elements in relation to one another and to the anchorage elements are obtained and stored.
