Question: 1 / 1180

Reduction of overbite can be accomplished most readily by which tooth movement?

Intruding maxillary incisors

In order to reduce an overbite, the maxillary incisors must be intruded. This is because when the upper front teeth (maxillary incisors) are pushed back, the lower front teeth (mandibular incisors) will naturally move forward, creating a more aligned bite. Uprighting maxillary and mandibular incisors (B) can help with overjet (horizontal distance between upper and lower front teeth) but will not significantly affect overbite. Using a high-pull headgear (C) or lip bumper (D) may help with overbite in some cases, but it is not the most efficient or direct method of reducing overbite. Therefore, the most appropriate option to address overbite is A intruding the maxillary incisors.
