Digital Model in Orthodontics

The purpose of ‘digital imaging’ in orthodontics is to display anatomical structure of a patient for proper diagnosis and treatment planning. Until now, imaging technology was limited to two dimensions. Some 3-dimensional (3D) imaging techniques have been developed but they are limited by the amount of information they can display and by their static nature. The development of an interactive 3-Dimensional digital model of a patient’s anatomy would greatly improve our ability to determine different treatment options, to monitor changes over time, to predict and display final treatment results, and to measure treatment outcome more accurately. But the main disadvantage is that it cannot be articulated. Digital orthodontic models are as reliable as traditional stone models and probably will become the standard for orthodontic clinical use. Now a days Study model, Digital radiograph and digital photography plays vital role in diagnosis and treatment planning of orthodonticpatient. This article describes about indication,advantages, disadvantage and the procedure of digital model.
