Abstract
Objective: 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 (SAOB).
Subjects and Methods: A sample of 22 patients with an age range from 14 to 22 years, suffering from skeletal anterior open bite (SAOB) with increased posterior maxillary vertical height. A new designed custom-made miniplates used after adaptation on 3D model of maxilla for every patient. They were used as buccal skeletal anchorage for maxillary molars’ intrusion. The 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.
Results: 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.
Conclusion: New custom-made preadapted 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.
