Multiply the number of pixels by the conversion factor. In this case, 170 x 1.29 = 219 pixels; 219 pixels is digitally equivalent to 11 mm (Fig. 25). Deter- mine the digital tooth width using the same for- mula. _Createanewlayer,leaveittransparent,andmark the measurement with the pencil tool (Fig. 26).

To enlarge or shrink the tooth grid created (with the layer activated), press command (or control) and “t” to bring up the free transform function. While holding the shift key (holding the shift key allows you to transform the object propor- tionally), click and drag a corner left or right to expand or contract the custom tooth grid. _Adjust the size of the grid so that the outlines of the central incisors have the new proposed length. Move the grid as necessary using the move tool so that the incisal edge of the tooth grid lines up with the new proposed length (Fig. 28). _Areas of the grid can be individually altered us- ing the liquify tool (Fig. 29).
