Abstract
BackgroundOrthodontic management of anterior open bites is a demanding task for orthodontists. Molar intrusion as a primary means of open bite correction entails the need for appropriate anchorage. Orthodontic mini implants can provide the required mechanical support. The suggested procedure aims to reduce the risk of complications such as root damage or soft tissue irritations while minimizing overall complexity.MethodsThree female patients aged 14, 18 and 19 years who decided against a surgical correction were treated with a device consisting of mini implants in the palatal slope, a palatal bar and intrusion cantilevers.ResultsIn all three patients, an open bite reduction of more than a millimeter occurred within four months. An anterior overbite of 2 mm or more could be established within 6 to 9 months.ConclusionsThe method presented in this article enables the practitioner to use mini implants in an easily accessible insertion site. A lab-side procedure is optional but not required.

Orthodontic management of anterior open bites is a demanding task for orthodontists
Only orthognathic surgery and orthodontic tooth movement remain as means of therapeutic intervention
Orthodontic solutions may involve an unfavorable extrusion of the incisors and may result in an increased display of gingiva [4]
Summary
Orthodontic management of anterior open bites is a demanding task for orthodontists. Molar intrusion as a primary means of open bite correction entails the need for appropriate anchorage. The management of anterior open bites is considered one of the most difficult tasks in orthodontics. A high-pull headgear can provide for an adequately directed force but depends on patient cooperation. It is usually not an option in adults. Skeletal anchorage using mini plates has been proven efficient in the management of open bites [5].
