Objective The aim of this study was to present a computer aided orthodontic bracket positioning system,which was based on 3D scanning,3D printing and orthodontic computer aided design (Ortho CAD).Methods Digital dental model was obtained by 3D scanning.By the aid of Ortho CAD,digital teeth were separated from virtual model and realigned based on the rule of Andrew's Six Keys.The positions of orthodontic brackets were calculated on individual digital tooth in the center of clinical crown with the diriction according to slot straighthening principle.The virtual teeth were then aligned back to their original position,and created a new dental model with bracket positioning marker by 3D printer.Based on the new dental model,an individual stent was produced for indirect bonding.To test the accuracy of the system,a simulated orthodontic treatment was performed through Typodont procedures.Results the Computer Aided Bracket Positioning System (CABPS) was established based on Ortho CAD,3D scanning and 3D printing.Conclusions CABPS could increase the accuracy of bracket placement and predictability of orthodontic treatment.
