Dental bridge composed of two bridge parts (1, 2) in which one, stationary bridge part (1) is built up of a metal core (11) having recesses (12) which correspond to tooth pins, of a ceramic material (13) as veneer for the metal core (11), and of a conical connection member (14) laterally projecting from this stationary bridge part (1), which corresponds to a recess (22), adapted to this connection member (14), in the metal core (21) of the second, detachable bridge part (2). The connection member (14) can be fixed in the recess (22) by means of a bar (3) tangentially penetrating the connection member (14). Mutually corresponding grooves (33, 34) are present in the bar (3) and in the metal core (21), and in these grooves a securing pin (4) which is shorter than the groove (32) terminating in front of the inner front surface (32) of the bar (3) is arranged. The free length of the groove (33) corresponds, for example, to the offset of a hollowing (35) in the bar (3), so that the hollowing (35) releases the connection member (14) on displacement of the bar (3) up to the front stop and the bridge part (2) can be detached. <IMAGE>
