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.

Figure 4: Treatment stages for case 1: initial situation (upper row), over-correction (middle row) and four months after intrusion appliance removal (lower row).

Mentions: An 18 year old woman with an anterior open bite was treated according to above method (Figure4). The negative overbite amounted to 3 mm between the upper and lower right lateral incisors. The smallest value - 0 mm - was established between the upper and lower left central incisors. The cephalometric analysis revealed a clockwise rotation of the mandible as well as a regular palatal plane angle.
