Abstract

Deep bite malocclusion is a frequent orthodontic problem and its correction with clear aligners remains biomechanically challenging due to limitations in vertical movement predictability. This study evaluated mechanical considerations and clinical outcomes of deep bite correction using clear aligner therapy in 30 patients. Pre- and post-treatment records were assessed for overbite reduction, incisor intrusion, molar extrusion, attachment protocols, staging design, and treatment duration. A significant overbite reduction was observed (5.5 ± 0.7 mm to 2.3 ± 0.6 mm), achieved mainly through maxillary (1.7 ± 0.4 mm) and mandibular incisor intrusion (1.4 ± 0.3 mm) with minimal molar extrusion (0.6 ± 0.2 mm). Clear aligner therapy was found to be effective for deep bite correction when proper biomechanical planning ensures controlled anterior intrusion and posterior vertical stability.
