The Accuracy of Computer Software Prediction of Soft Tissue Profile for Patients Undergoing Fixed Orthodontic Treatment

Al-Azhar University30 enrolled

Overview

A clinical study to evaluate the accuracy of computer software in predicting soft tissue profile changes in patients undergoing fixed orthodontic treatment

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

Study Type

Conditions

Dental Malocclusion

Interventions

Accuracy of computer software in predicting soft tissue profile changesOTHER

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.

The inclusion criteria included: * Patient undergo fixed orthodontic treatment with the edgewise technique. * Skeletal class I. * Dental class I or II or III. * Final class I occlusion without spacing or crowding, with normal overjet and overbite (2-4 mm) * Availability of full diagnostic and therapeutic records before to and following orthodontic treatment, including medical and dental history, dental casts, panoramic and cephalometric x-rays, and photographic photographs. The exclusion criteria included: * Missing tooth or significant Bolton discrepancies (more than 3 mm). * Craniofacial syndromes or skeletal abnormalities. * Failed orthodontic treatment in the past. * Cosmetic or reconstructive facial surgery during orthodontic treatment, or up to a year beforehand. * Using drugs that could reduce the volume of soft tissues.

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 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.
