Introduction: The objectives of orthodontic treatment are to achieve a functional, aesthetic and sustainable occlusion. However, its analysis is often limited to the study of its buccal side, easy to check in mouth. Yet, the lingual occlusion is also of paramount importance.
Material and method: After calling to mind the ideal static objectives of treatment, described by some authors and defined by some scientific societies, this article studies the different supports for the analysis of lingual static occlusion and proposes a new protocol for the carving of orthodontic casts.
Results: The lingual occlusion end-of-treatment objectives lack details, whether by the scientific societies or literature, although we possess simple ways to study them.
Discussion: The lingual part of occlusion is rarely studied in our daily practice, particularly because its analysis cannot be achieved by a direct intraoral examination. However, it is of major importance in the success and stability of our treatments.
