Abstract

Successful orthodontic treatment is based on comprehensive diagnosis and treatment planning. A few of the fundamental factors in the diagnosis are the spacing condition, tooth size, arch form and its dimensions, the tooth-arch discrepancies, palatal depth and palatal length. The model analysis is a time-consuming procedure. Nevertheless, it is a vital part in the diagnosis and subsequent treatment planning process. However, in a day-to-day practice many orthodontists judge the models subjectively, without applying analytical tests. Traditionally, measurements on dental casts are performed with the aid of either Vernier calipers or needle pointed dividers. By using these methods, a clinically significant measurement error (>1.5 mm) can occur. The measurement of palatal depth and palatal length cannot be done by using these methods. These measurements are important to orthodontist to diagnose, plan and execute treatment in each patient. Alternatively, measurements on photocopies, photos, holograms, or digitization of points from the casts had been proposed, but these methods demonstrated errors as well.
