An intermediate cement 3 is set between a component to be fixed 2 and its support 1 with the help of an electric current of suitable sign, which can in particular cause a polymerisation reaction, separation of the luted (sealed) component remaining possible by application of a current of opposite sign. This process applies to luting (sealing) of crowns in dentistry, and it also allows obturations to be made. <IMAGE> |
