Orthodontic treatment of anterior open bite

Abstract

It is increasingly common for orthodontists to perform compensatory treatments for the correction of malocclusions presented by their patients, through a mechanism that is efficient and enables good results and long-term stability. An open vertical bite is defined as an open bite between the upper and lower incisal borders. It is one of the malocclusions of greater functional aesthetic impairment, with several etiological factors involved. It is emphasized that it is a discrepancy in the vertical direction, making it more difficult to correct and with less stability in its final results. Given the above, the objective of this article is to review the literature on orthodontic treatment in anterior open bite. The methodology used was an integrative literature review. In the first stage of the study, 227 articles were found, which referred to the orthodontic treatment of the anterior open bite (MAA). After reading the titles of the selected articles, 112 articles were selected. After reading the abstracts, only 55 studies were selected to be included in the critical and integral reading. Finally, 13 studies met the inclusion criteria. In clinical situations where a diagnosis is anterior open bite, during the mixed dentition period, the treatment option is the indication of the removable acrylic with Hawley's arch, the expander screw and palatal grid. However, it is important to note that success treatment in this case is also due to the cooperation of the patient.
