Reliability of Software Prediction of Post Orthodontic Treatment Changes

Aim The aim of this study was to assess the accuracy Dolphin VTO prediction in patients requiring extraction treatment by comparing VTO-predicted values and post-treatment values. Method Digital pre lateral cephalograms 52 having Class I bimaxillary protrusion were taken transferred Imaging software for analysis prediction. A composite made containing 17 dental soft tissue parameters (Holdaway, Mc Namara, Rakosi, Steiners, Tweed analysis). Results comparison between showed that able predict changes accurately regions such as nose, inferior sulcus depth, chin region ( p > .05). In changes, inclination upper incisors Sn palatal plane correctly Parameters other areas lower lip, position incisor show significant difference their < .05) showing inaccuracy software. Conclusion significantly different from superior lip h line, subnasal thickness, strain, nasolabial angle, interincisal Ui-NA, Li-NB, IMPA. For nasal prominence, UI-SN, UI-PP, there no seen. Since, most parameters, a found predicted values, so it inferred software-based could not be fully relied any planning.
