A manufacturing system for dental products (P, P') operates with coordinating units (9) which receive and register orders from customers (1, 2 and 3). The coordinating units distribute the order to production units (11, 12 and 13). The various units include database whose contents are updated by data replications in conjunction with changes to system functions, system application, system structure, etc. The data contained in the databases of the production units are entered in memory elements which are arranged for accessing program contents when executing data replications via one or more interfaces via which the function for data replications in the system has access or is effected.
