Bottom Line: The suggested procedure aims to reduce the risk of complications such as root damage or soft tissue irritations while minimizing overall complexity.The 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.

ABSTRACT

Background: 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. 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.

Methods: Three 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.

Results: In 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.

Conclusions: The 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.

Mentions: Posterior intrusion was achieved through distally extended cantilevers fabricated out of 16×22 stainless steel wire. The connection between implant neck and wire was established by bending the anterior end of the wire into the shape of a clip (Figure2). This clip permitted for a rigid connection between the wire and the implant neck. The distal end of the wire had to be designed in a way that involves as little soft tissue irritation as possible. Therefore, a smooth hook shape was chosen. A gable bend distal of the clip caused the cantilever to point towards the roof of the palate (Figure3).
