Title (EN) METHOD FOR THE PREPARATION OF DENTAL PROTHESES BY PHOTOPOLYMERIZATION OF A PLASTIC MASS
(FR) PROCEDE POUR LA PREPARATION DE PROTHESES DENTAIRES PAR PHOTOPOLYMERISATION D"UNE MASSE PLASTIQUE
Abstract: front page image
(EN)Dental protheses of stable colour, having good mechanical properties may be obtained by photopolymerization of stable preparations with a component based on ethylenically unsaturated monomers as well as excipients and colorants when, in order to obtain good rates of polymerization, there are added bicyclo-(2.2.1)-heptane-dione 2,3 compounds mixed optionally with amines as photoinitiators, their proper yellow coloration being durably bleached after a short primary exposure to visible light in order to fix it thereafter by intensive exposure to visible light.
(FR)Des protheses dentaires de couleur stable, ayant de bonnes proprietes mecaniques peuvent etre obtenues par photopolymerisation de preparations stables a un composant a base de monomeres non satures ethyleniques ainsi que d"excipients et colorants lorsque en vue d"obtenir de bons degres de polymerisation, on ajoute des composes bicyclo - (2.2.1) -heptane-dione 2, 3 melanges le cas echeant a des amines comme photoinitiateurs et qu"on blanchit durablement leur propre coloration jaune apres une courte exposition primaire a la lumiere visible pour la fixer ensuite par une exposition intensive a la lumiere visible.
