Contemporary diagnosis of anterior interarch tooth size discrepancy.

摘要

The Bolton Analysis has long been accepted in orthodontics as a diagnostic test to detect, localize and quantify anterior interarch tooth size discrepancy (ITSD). Although the Bolton Analysis has served orthodontics well, current restorative modalities, esthetic concepts and other important clinical factors not available or appreciated at the time of Bolton's work warrant a reassessment of the Bolton approach to anterior ITSD diagnosis and treatment. Bolton's methods and assumptions were analyzed to assess use of the Bolton Analysis for contemporary diagnosis and treatment of anterior ITSD. Limitations of the Bolton Analysis were identified and an improved method for contemporary diagnosis of ITSD was proposed.
