Summary
Measuring the accuracy of a new technique by which root positions can be predicted at the pre-finishing stage of the comprehensive orthoodntic treatment
Detailed description
A CBCT is taken Pre-Treatment Segmentation of teeth is done from the CBCT exported as STL files and kept aside. Routine comprehensive orthodontic treatment is done till pre-finishing stage. Impression for teeth is taken at this timepoint. A cast is poured and laser scanned. Now the investigators have segmented teeth and a cast with new crown positions The investigators will superimpose the teeth on the crowns of the digital cast to obtain the " Predicted Root Position" (PRP) To check accuracy of this Prediction a CBCT is taken and compared to the prediction to check its accuracy.
