| Summary | This prospective observational clinical study aims to evaluate the three-dimensional surface wear and clinical survival of orthodontic attachments fabricated with customized composite materials used in clear aligner therapy. Attachments play a critical role in the biomechanical efficiency of aligner treatment by facilitating planned tooth movements. However, the mechanical and surface properties of the composites used for attachment fabrication may affect their wear behavior and long-term stability. In this study, four different composite materials will be tested using a split-mouth design in patients treated with clear aligners. Each quadrant will receive a different composite, including both customized and universal types. All attachments will be fabricated using standardized digital tem |
