A unit forms part of a dental bridge construction or template therefor. The unit comprises a shell formed by a latex tube and, arranged in the latter, a carbon fiber arrangement wetted with matrix material. The unit forms a unit which can be delivered from a factory and in which the carbon fiber arrangement is optimally wetted with matrix material comprising a one-component material without an excess of base or hardener. The unit is designed to be able to assume a state in which the matrix material is only partially polymerized. In this state of the matrix material, the unit can be stored at a temperature which delays the polymerization of the matrix material in order to permit deferred use in connection with the dental bridge construction or the template. The unit is designed so that, at the time of said use, it can be exposed to a polymerization temperature which, after the desired shaping of the unit, causes substantially accelerated solidifying of the unit in its final shape.
