Accuracy and reliability of the expected root position setup methodology to evaluate root position during orthodontic treatment
Introduction Current methods to evaluate root position either are inaccurate (panoramic radiograph) or expose patients to relatively large amounts of radiation (cone-beam computed tomography [CBCT]). A method to evaluate root…
Occlusal changes during a 10-year posttreatment period and the effect of fixed retention on anterior tooth alignment
Introduction The objectives of this research were to evaluate changes in occlusal components in 3 subperiods during a 10-year posttreatment time span and to examine the long-term effects of fixed…
Comparison of statural height growth velocity at different cervical vertebral maturation stages
Introduction Knowledge of a patient’s stage of growth and development plays a vital role in diagnosis, treatment planning, results, and stability of the outcome. Cervical vertebral maturation (CVM) predicts the…
