Accuracy of Digital Imaging Software to Predict Soft Tissue Changes during Orthodontic Treatment

Area of Science:

• Orthodontics and Dental Imaging

Background:

• Accurate prediction of soft tissue changes is crucial for orthodontic treatment planning.
• Digital Imaging software is increasingly used to simulate treatment outcomes.

Purpose of the Study:

• To evaluate the accuracy of Dolphin Imaging software in predicting soft tissue alterations.
• To compare prediction accuracy across non-extraction, extraction, and orthognathic surgery interventions.

Main Methods:

• Cephalometric analysis of 96 patients undergoing three orthodontic interventions.
• Comparison of predicted versus actual post-treatment soft tissue changes using Dolphin Imaging software (v11.9).
• Paired t-tests were used to determine statistical significance (p < 0.05).

Main Results:

• Prediction errors ranged from 0.3-1.0 mm in specific parameters across all groups.
• Non-extraction group: errors in lower lip parameters.
• Extraction group: errors in upper and lower lip parameters.
• Orthognathic surgery group: errors in chin thickness, facial contour angle, and lip parameters.

Conclusions:

• Dolphin Imaging software demonstrates inaccuracies in predicting soft tissue changes for orthodontic treatments.
• These prediction errors necessitate careful consideration during orthodontic treatment planning.
• The software's accuracy varies depending on the type of orthodontic intervention.
