The present invention provides a laterally movable lifting arm and follower which may be mounted adjacent a mold. In one embodiment, the structural filler has a refractive index substantially similar to that of the polymerizable resin, a coarse particle fraction, and a fine particle fraction having a mean particle size greater than 0. The sequence of user actions is based at least in part on the graphically illustrated actions populated into the template. Each clamping jaw has a bore aligned with one another to receive a screw, wherein a pivot bearing is arranged opposite said cavity allowing the two opposing clamping jaws to come in contact to one another.
