Abstract

Anterior open bite is a malocclusion characterized by a negative overlap between the incisal edges of the upper and lower teeth. The etiology is multifactorial, normally associated with common factors such as non-nutritive sucking, tongue interposition, nasopharyngeal obstructions, respiratory and skeletal factors. The treatment of this condition in adulthood in moderate to severe cases is difficult because the jaw bones are already formed, leaving orthognathic surgery as the ideal treatment for this condition. With the advent of skeletal anchorage devices, a new treatment option for this condition has become viable. Mini-implants are a skeletal anchorage tool that can be used in molar intrusion mechanics during orthodontic treatment. The use of mini-implants has several advantages and is an effective alternative to meet the demand of adult patients seeking treatment, mainly to close skeletal anterior open bites. However, recurrence rates in this treatment also exist, as in other treatments. Being greater in the first year after treatment, highlighting the importance of containment mechanisms and interceptive treatment of this condition, when possible, during the individual’s growth. Therefore, this work aims, through a literature review, to evaluate the use of mini-implants as skeletal anchorage in molar intrusion mechanics.
