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

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

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

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.
