Abstract :

This study aimed to evaluate the effect of newly designed miniplates that used as skeletal anchorage for maxillary molars’ intrusion during correction of skeletal anterior open bite. A sample of 22 patients with an age range from 14 to 22 years, suffering from skeletal anterior open bite with increased posterior maxillary vertical height. A new designed custom-made miniplate used after adaptation on 3D model of maxilla for every patient. They were used as buccal skeletal anchorage for maxillary molars’ intrusion. Measurements, including maxillary dento-alveolar heights (mm), buccal crestal alveolar bone heights (mm), bucco-palatal angulations (B-P⁰) of right and left maxillary first permanent molars, 3 months after intrusion commencement. The dento-alveolar height as well as the buccal crestal alveolar height decreased significantly (p≤0.001 and p≤0.05, respectively) after intrusion. Similarly, the B-P angulations increased significantly (p≤0.01) after intrusion. New custommade pre-adapted miniplates’ designs were effective for posterior maxillary molar intrusion in cases of SAOB. Both the posterior maxillary dento-alveolar and buccal crestal alveolar bone heights diminished significantly.
