Measuring a Sample of Orthodontic Models/Panographs at LLUSD Using the CR-Eval
<p>Introduction: An index must be used to quantify the improvement in the position of teeth treated by orthodontics. The Cast-Radiograph Evaluation is the index used by the American Board of Orthodontics. The purpose of this study is to use this index to evaluate treatment outcomes in the graduate …

CBCT Evaluation of Morphological Changes to Alveolar Bone Due to Orthodontic Tooth Movement
<p>Introduction: The mandibular process is the anatomic factor that limits the orthodontic movement of the mandibular incisors, and awareness of this structural limitation may reduce the risk of potential damage to tooth roots and alveolar bone. A decision regarding the correct placement of the …
