Brief Summary

The windowed direct-indirect bonding is a new bonding technique that could provide a simple and cheap method for fast and precise brackets bonding. There are still not enough studies to evaluate the effectiveness of this method in terms of accuracy, bonding time, bonding failure and cost. This study is designed to answer these questions and compare the forementioned bonding technique with digital indirect bonding and finally provide the clinician a recommendation on the best bonding technique. This study introduces as well a new method of fabrication of the windowed template using Fusion Deposition Modeling (FDM) 3D printing technology.

Outcome Measures

Primary Outcomes (1)

  • Bonding accuracy

    Deterring the accuracy of bracket position

    After bonding immediately

Secondary Outcomes (1)
