Two software programs for predicting orthognathic surgery outcomes showed similar overall accuracy. Dolphin Imaging excelled at chin and submandibular predictions, while Dentofacial Planner Plus was better for lip and nasolabial angle predictions.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Medical Imaging and Simulation
Background:
- Computer software aids in predicting orthognathic surgery results.
- Evaluating the subjective accuracy of soft-tissue surgical simulations is crucial for treatment planning.
Purpose of the Study:
- To subjectively compare the soft-tissue surgical simulation accuracy of two distinct software programs.
- Assess the clinical utility of predictive software in orthognathic surgery planning.
Main Methods:
- Ten patients with Class III malocclusion underwent double-jaw orthognathic surgery.
- Dentofacial Planner Plus and Dolphin Imaging software predicted post-surgical profiles from standardized photographs.
- 101 dental professionals evaluated predictive images against actual outcomes.
Main Results:
- Dolphin Imaging demonstrated superior prediction for the nasal tip, chin, and submandibular region.
- Dentofacial Planner Plus showed better accuracy in predicting the nasolabial angle and lip positions.
- No statistically significant difference was found between the two software programs in overall profile prediction.
Conclusions:
- Both software programs are comparable for generating 2D predictive profile images in orthognathic surgery for Class III malocclusion.
- The choice of software may depend on specific facial areas of interest for prediction.
