  • Method for adapting and implanting a dental porcelain chip, and the chip
    Patent number: 5358406
    Abstract: A method is disclosed for adapting and implanting at least one dental porcelain chip (9) in a cavity (2, 3, 4). The cavity and each porcelain chip (9) are subjected to necessary etching, silanization, and application of a binder before implantation occurs. At first, a moulding (10a) is made of the cavity (2, 3, 4), whereupon the moulding (10a) is fastened to the porcelain chip (9). Then the porcelain chip is contour worked to substantially the same shape as the moulding (10a), and the formed chip (9c) is placed in the cavity and fastened by means of a binder to the original tooth (1).
