Detailed Description
The computer software programs exhibit certain soft tissue simulation . The purpose of the study to assess the accuracy of computer software in predicting profile changes in patients undergoing fixed orthodontic treatment

| A real photoes (after treatment) |
Other: Accuracy of computer software in predicting soft tissue profile changes
Separate analyses will be performed on the initial and final cephalograms.
All of the cephalometric analyses will be done via computer software,the linear and angular measurements will be done via the software.
Through the use of software, the initial cephalogram and the initial photograph will be linked.
Then, the final values of some angles will be tracted from the post-treatment cephalogram.
These values will be inserted in the "treatment simulation"section of the software.
A post-treatment projected image of the patient will be simulated by the software.
Then the actual post-treatment photograph will be placed on the simulated image in transparent form.
From the pupil , real horizontal and vertical reference lines will be drawn.
Then certain measurements will be taken from referance lines to fixed points on the soft tissue to determine the discrepancies between the real and simulated images.

Outcome Measures
Primary Outcome Measures
- accuracy of computer software in predicting soft tissue profile changes [through study completion, an average of 1 year]
Separate analyses will be performed on the initial and final cephalograms. All of the cephalometric analyses will be done via computer software; the linear and angular measurements will be done via the software. Through the use of software, the initial cephalogram and the initial photograph will be linked. Then, the final values of some angles will be extracted from the post-treatment cephalogram. These values will be inserted in the "treatment simulation" section of the software. A post-treatment projected image of the patient will be simulated by the software. Then the actual post-treatment photograph will be placed on the simulated image in transparent form. From the pupil , real horizontal and vertical reference lines will be drawn. Then certain measurements will be taken from reference lines to fixed points on the soft tissue to determine the discrepancies between the real and simulated images.
