How to study and rapidly correct the shape of teeth

To adapt the shape of teeth accurately, it is essential to outline their contours and transition points with a pencil.

Whereas a color will be used to underline the transition angles and the convexitites in the work model, the opposite color will be used to outline the outer contour of the teeth. The tip of the pencil will be used to draw the desired ideal angles. The corrections will be drawn with the opposite color.

Wherever the blue is superimposed on the red, this means that the transition angle is correctly positioned, when the blue is shifted, this indicates that a correction is required.

Working this way, we gain a considerable time, and our work is much more accurate. This method is very effective Another quality of this pencil is its complete calcination.
