Tooth movement tracking system
Systems and methods are disclosed for determining movement of a tooth model from a first position to a second position by identifying one or more common features on the tooth model; detecting the position of the common features on the tooth model at the first position; detecting the position of the common features on the tooth model at the second position; and determining a difference between the position of each common feature at the first and second positions.
1 . A method for determining movement of a tooth model from a first position to a: second position, comprising:
identifying one or more common features on the tooth model;
detecting the position of the common features on the tooth model at the first position;
detecting the position of the common features on the tooth model at the second position; and
determining a difference between the position of each common feature at the first and second positions.
2 . The method of claim 1 , comprising:
forming the model of the tooth at the first position; and
forming the model of the tooth at the second position.
3 . The method of claim 1 , wherein the position detecting comprises mechanically sensing the position.
4 . The method of claim 3 , comprising using handheld 3D digitizers.
5 . The method of claim 1 , wherein the position detecting comprises chamfer matching.
6 . The method of claim 1 , wherein the position detecting comprises sparkling.
7 . The method of claim 1 , wherein the position detecting comprises laser marking a tooth model.
8 . The method of claim 1 , wherein the position detecting comprises marking an FACC line.
9 . The method of claim 1 , wherein the position detecting comprises manually measuring the difference between first and second positions.
10 . The method of claim 1 , wherein the position detecting comprises setting up a wax model.
11 . A system for determining movement of a tooth model from a first position to a second position, comprising:
means for identifying one or more common features on the tooth model;
means for detecting the position of the common features on the tooth model at the first position;
means for detecting the position of the common features on the tooth model at the second position; and
means for determining a difference between the position of each common feature at the first and second positions.
12 . The system of claim 11 , comprising:
means for forming the model of the tooth at the first position; and
means for forming the model of the tooth at the second position.
13 . The system of claim 11 , wherein the position detecting comprises mechanically sensing the position.
14 . The system of claim 13 , comprising using handheld 3D digitizers.
15 . The system of claim 11 , wherein the position detecting means comprises chamfer matching means.
16 . The system of claim 11 , wherein the position detecting means comprises sparkling means.
17 . The system of claim 11 , wherein the position detecting means comprises means for laser marking a tooth model.
18 . The system of claim 11 , wherein the position detecting means comprises means for marking an FACC line.
19 . The system of claim 11 , wherein the position detecting means comprises means for manually measuring the difference between first and second positions.
20 . The system of claim 11 , wherein the position detecting means comprises a jig for wax model set-up.
