Study on the Effectiveness of 3D-Printed Shape Memory Clear Aligners for Treating Adult Anterior Open Bite

What this Trial Is About

This research aims to study the use of 3D-printed shape memory aligners for treating adults with anterior dental open bite. It compares three groups patients using conventional clear aligners with attachments, those using 3D direct-printed shape memory aligners without attachments, and those using 3D direct-printed shape memory aligners with attachments. The study explores their effects on molar intrusion, anterior teeth extrusion, stress distribution, and initial tooth displacement. Participants will wear clear aligners for about 6 to 8 months depending on their assigned group. The aligners include conventional thermoformed and direct 3D-printed shape memory types, some with rectangular attachments bonded to teeth. The treatment includes digital scanning, custom aligner design, and aligner insertion with instructions to wear them at least 22 hours per day. Initial measurements and imaging like CBCT and intraoral scans are taken before and after the first series of 15-20 aligners. Throughout the study, participants undergo assessments including cephalometric analysis, CBCT imaging, and patient-reported outcome measures PROMs on pain, mobility, strength, and satisfaction before and after treatment. Compliance is self-recorded and monitored. The study will evaluate dental and skeletal changes, molar intrusion, and tooth movement using advanced imaging software and finite element analysis. Participation lasts about 8 to 14 months, with data collected at baseline and after the first aligner series.
