Aesthetic reasons: dental malpositions
Dental overlaps cause a more or less embarrassing aesthetic concern. They can also eventually cause periodontal disease (gum disease) by food retention and plaque and scale deposits.




Palatal bite
When the upper teeth are placed too much forward with respect to the lower teeth, the lower incisors collide with the retroincising palatal mucosa (behind the upper teeth). A loosening of the upper anterior teeth can occur, causing bone loss that can cause anterior mobility.

Difficulty incision and chewing especially in cases of superior prognathism and significant lower retrognathism


Risk of coronary fracture of upper incisors if they are too far forward after a fall


Risk of installation of maxillofacial bone asymmetry in case of posterior cross articular


Risk of periodontal disease in case of an open bite


Implementation of vestibular and palatal canines using mini-implants and / or sectional arches
