Accuracy of Digital Three-Dimensional Root Position Prediction Via Digitized Models

Accuracy of Digital Three-Dimensional Root Position Prediction Via Digitized Models

Measuring the accuracy of a new technique by which root positions can be predicted at the pre-finishing stage of the comprehensive orthoodntic treatment

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.

Inclusion Criteria:

• Patients requiring orthodontic treatment
• Adult set of permanent dentition
