Method and apparatus for polymerising light-hardening dental fillings of class II type composite material

摘要

In a method of preparing a class II dental filling of a light- hardening filling material in a drilled-out tooth surrounded by a matrix band, the drilled-out tooth is filled with a light-hardening filling material in which the lower part of a light-transmitting adapter having a recess and attached to a light conductor, is pushed down into a filling material so that light is spread in the deeper parts of the filling, while at the same time the lower part of the adapter is pressed against the point of contact of the adjacent tooth while the filling is hardened so that satisfactory approximal contact is obtained.PPA light-transmitting adapter comprises an upper part having a recess for receiving a light conductor and a conical lower part adapted to conduct light-hardening filling material down into a drilled-out tooth. The lower part of the adapter is pressed against a matrix band surrounding the tooth so that satisfactory approximal contact with the adjacent tooth is obtained, while at the same time the deeper parts of the filling are made accessible to light from the light conductor.
