TREATMENT PLANNING WITH DIGITAL ORTHODONTIC MODELS Jean-Marc Retrouvey, Liliya Nicholcheva, Nathan Light INTRODUCTION Digital orthodontic models are an accurate and reliable record of the patient’s occlusion. In addition, new software allows sectioning and alignment of teeth on the model to simulate or predict the result of orthodontic treatment. Recent studies have shown that these digital predictions of treatment outcomes are comparable with actual post-orthodontic treatment outcomes OBJECTIVE AND HYPOTHESIS The purpose of this project is to assess the proficiency of digital orthodontic models in predicting the outcomes of several possible orthodontic treatment plans. MATERIALS AND METHODS Case 1 – Severe Class II Div I malocclusion  Slight maxillary prognathism  Severely proclined maxillary incisors  Slight mandibular retrognathism  Slight proclined mandibular incisors
