Tooth separation systems and methods

A tooth separation system comprising:

• a loading unit is configured to load an intraoral scan data;
• a display unit is configured to display the intraoral scan data loaded by the loading unit, in which the intraoral scan data includes a tooth as well as gums;
• an input unit is configured to make a tooth border mark onto the tooth shown on the display unit;
• and
• a calculation unit is configured to perform necessary calculations to separate the tooth from the gums based on the tooth border mark, wherein:
• the tooth border mark comprises a larger shape and a smaller shape fit inside the larger shape;
• each of the larger shape and the smaller shape is a closed curve;
• a plurality of points is automatically plotted within the larger shape and the smaller shape;
• and
• the calculation unit is configured to separate the tooth from the gums based on the plurality of points plotted within the smaller shape and the plurality of points plotted between the smaller shape and the larger shape.
