Orthodontic Correction of an Anterior Open Bite with Periodontally Compromised Upper Incisors Using Miniscrews

This case report describes the camouflage treatment of a patient with an anterior open bite, bimaxillary skeletal protrusion with a mild class II skeletal pattern, reduced periodontium with generalized slight bone loss, localized severe bone loss at the maxillary upper incisors, and a tongue thrust habit. Orthodontic treatment included modifying the resting posture of the tongue and sectionally intruding maxillary posterior teeth while controlling the extrusion of mandibular posterior teeth using temporary anchorage devices (TADs), followed by sectional mechanics at the maxillary arch and continuous arch mechanics at the mandibular arch, along with interpromximal reduction at the mandibular teeth and inter-arch elastics from the mandibular teeth to the maxillary TADs to minimize orthodontic force magnitude and duration specifically applied to periodontally compromised maxillary incisors. The patient’s chief complaint was addressed, and treatment objectives were achieved, with good esthetic and occlusal outcomes. Stability was shown over a 56-month follow-up period.
