Abstract
A method for manufacturing a fiber rein-forced composite dental restoration comprising the steps of (i) preparing a mould; (ii) filling the cavity of the mould with a fiber-reinforced polymerizable material comprising an organic matrix and a fiber component embedded within the matrix; (iii) applying pressure to the fiber-reinforced polymerizable material; and (iv) curing the fiber-reinforced polymerizable material. The method is characterized in that the mould is designed in a way which allows excess organic matrix material to escape form the cavity during pressing.
