Abstract
Purpose
We aimed to use lateral and oblique radiographs to evaluate dental and skeletal changes arising from maxillary molar intrusion with zygomatic anchorage in open bite patients.
Methods
We conducted a pilot study including nine patients (six females and three males; mean age, 18.7 ± 5.1 years) with skeletal open bite treated with titanium miniplates for posterior dentoalveolar intrusion. Lateral and oblique (right and left, 45°) radiographs were obtained before (T1) and 6 months after intrusion (T2). A paired t test was used for statistical evaluation.
Results
The maxillary posterior teeth were intruded 2.03 ± 0.87 mm (p < 0.01) with 450×g of force, which resulted in counterclockwise rotation of the mandible (1.57°, p = 0.02) and clockwise rotation of the occlusal plane (4.27 ± 2.66°, p = 0.01). Anterior facial height decreased by a mean of 1.79 ± 1.51 mm (p < 0.01). No significant change in the palatal plane or in anteroposterior molar movement was observed.
Conclusion
The oblique radiograph at 45° was useful for the assessment of molar intrusion and anteroposterior displacement. The treatment of anterior open bite with skeletal anchorage provided intrusion of molars and counterclockwise rotation of the mandible, resulting in open bite closure.
