Abstract
A device for obtaining the fitting of a matrix to a tooth to be filled comprises matrix (5) and wedge (4) or its attachment part (7) made of resin 'with memory that is deformable by illumination'. The device is made such that when it is illuminated it deforms and pushes matrix (5) to precisely occupy the radicular recess of the tooth to be filled, while when it is not illuminated it again assumes its normal shape. Thus, one obtains a perfect filling that perfectly fits the shape of the tooth.
