Investigate the Effectiveness of 3D-printed Shape Memory Aligners in the Treatment of Anterior Open Bite

Recruiting now · Not applicable

Conditions studied: Open Bite

In brief

The goal of this randomised clinical trial study is to investigate 3D-printed shape memory aligners in the treatment of anterior dental open bite adult patients. The main questions it aims to answer are: 1. Do 3D-direct-printed shape memory aligners demonstrate potentiality in the management of AOB? 2. What is the effect of 3D-direct printed shape memory aligners on molar intrusion? 3. Can the 3D-direct printed shape memory aligners extrude anterior teeth without the use of attachments? 4. Do 3D-direct printed shape memory aligners generate greater/higher stress distribution and initial teeth displacement compared to conventional clear aligners? Researchers will compare three groups: Group I: Patients treated with conventional clear aligners with attachments; Group II: Patients treated with 3D direct-printed shape-memory aligner without attachment; Group III: Patients treated with 3D direct-printed shape memory clear aligners with attachments and see its effect on anterior open bite treatment. Participants will wear a clear aligner for about 6-8 months. Then
