Permanent incisor eruption is done in a harmonious way when the conditions of the dentoalveolar arches development are all united. This is not always the case, obstacles to growth as orofacial dysfunctions (improper swallowing, mouth breathing, and speech defects) or finger sucking can disrupt the eruptive process of these permanent teeth. Indeed, the incisor proclination is the most common abnormality observed among our patients. The impact is felt on the esthetic of the smile, essential parameter of the demand for orthodontic treatments. The clinical form and degree of severity depend on the etiological factors and the relevant dentoalveolar or skeletal structures involved in the onset of incisor relationship abnormalities. The therapeutic approach is chosen taking into account these factors but also the age of the patient and the stage of growth.
The incisor proclination when pronounced requires a large incisor repositioning and consequently space on the arches. Often associated with Class II skeletal discrepancy and dental crowding, the exaggerated overhang is corrected by dental extractions and incisor recoil particularly when the treatment is late. So, it is preferable to opt for early treatments mainly when the incisor proclination is related to a functional etiology, the chances of success are greater in the short and long term. The orthodontic treatment using a trainer allows a functional education and so the interception of incisor protrusion.
