The cavity can be filled for example with epoxy resin and can be removed as split cast base (1) via the mould parting line (12) after splitting of the mould (11). Alternatively, there is proposed a mould block (15) which contains exchangeable moulds (18) which can be formed in the plastic phase of an impression material (14) with the negative of the parent plate to give a mould unit (18) with mould cavity (16). The preferred impression material (14) is silicone of optimum viscosity and having a retention element (not shown) and, where appropriate, a magnet for placement of the retention plate (3). In the plastic phase of the base material it is reasonable also to integrate additional retention elements (4). <IMAGE>
