Abstract

Synthetic polymerizable materials, such as methyl methacrylate and mixtures thereof with polymethyl methacrylate, are polymerized in contact with a surface with which the polymerized material should exactly conform by coating the surface with a polymerization catalyst, and then applying the polymerizable material to the catalyst layer whereby polymerization proceeds in a direction away from the surface to be reproduced. Suitable surface catalysts are tertiary amines, such as dimethylaniline and sulphines, which may be applied in a varnish containing, e.g. nitrocellulose, mastic, or tricresyl phosphate dissolved in butyl alcohol, ethyl acetate, ethyl lactate, or ethyl ether. The polymerizable material may also contain a catalyst such as benzoyl peroxide or a mixture thereof with dimethyl aniline. The process may be employed in making dental and anatomical prostheses, artificial teeth, tooth fillings, and in moulding clasps and needles into polymerized material.
