Directional force treatment for an adult with Class III malocclusion and open bite.

The orthodontic treatment of an adult patient with a Class III malocclusion and an anterior overbite is presented. Successful treatment required a differential diagnosis, specific planning, and careful control of the force systems to correct the disharmony in the vertical and horizontal dimensions. Fundamental to the successful treatment was the direction of the force applied to the teeth with a J-hook headgear. This directional force application made it possible to successfully correct the malocclusion without undesirable sequelae.

Noncompliant treatment of skeletal open bite.

The purpose of this article is to illustrate the effects of the rapid molar intrusion appliance, a treatment alternative that does not require patient compliance, for counteracting excessive vertical dimensions in growing patients and adults. The rapid molar intrusion appliance has 2 elastic modules that are secured on the maxillary and mandibular first-molar tubes. It is used in combination with maxillary and mandibular soldered lingual arches. Patient acceptance is good, and the patient's only responsibilities are to keep the appliance clean and avoid breakage.

Modified maxillary protraction headgear for the correction of class III skeletal malocclusion with anterior open bite.

This is a case report of a 10-year-old girl with a hyper divergent class III skeletal malocclusion caused primarily due to maxillary retrognathism. Treatment involved the use of a modified maxillary protraction face mask that carries the point of force application extra orally to pass through the centre of resistance of the maxillary dentoalveolar complex. After 8 months, the maxilla was displaced anteriorly without rotation. Maxillary occlusal plane showed a clockwise rotation. Maxillary incisors were extruded and retroclined. Mandible was displaced downward and backward. Another 18 months were required for fixed orthodontic treatment to achieve perfect interdigitation.
