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: Instead of a gingival collar the Jet Screw (JS) type mini implants (Promedia Medizintechnik GmbH, Siegen, Germany) used in this work have a long neck which widens towards the implant head. This makes them applicable in areas covered by thick soft tissue. They are advertised for use with the TopJet Distalizer (H. Winsauer, Bregenz, Austria; Promedia Medizintechnik GmbH, Siegen, Germany). The insertion site recommended by the manufacturer is located at half of the distance of the perpendicular line segment from the raphe to the palatal cusp tip of the first bicuspid (Figure1).
