<p>Conventionally, matrix use is required for Class 2 cavity fillings. However, it entails a number of problems, including the fact that there are many circumstances under which matrix placement itself is difficult, as well as the difficulties of achieving a fit that can be described as perfect under microscope observation and of reproducing proximal surface morphology that comprises anything but a single contour. Filling methods using flow control have recently been described for use in cavities that occupy a relatively restricted area, but this method is more difficult to achieve when extensive filling is required. I have devised a novel technique that enables the filling of extensive Class 2 cavities without the use of a matrix. This method uses microscope illumination to start the gradual hardening of flow resin while reproducing the proximal surface morphology by building up layers of resin in three dimensions in the same way as a material-jetting 3D printer. The use of this method enables the recreation of the shape of the proximal surface and the contact point for even comparatively large proximal surface cavities without the use of a matrix.</p>
