Using a digital workflow in orthodontics and interdisciplinary dentistry undoubtedly benefits both the patient and the professional. This nine-step protocol guides orthodontists through an interdisciplinary treatment planning and execution. Firstly, it establishes an exhaustive digital diagnosis and then formulates an interdisciplinary digital treatment plan with precise 3D goals. Finally, objective verification of the treatment results occurs through 3D superimposition. This protocol addresses the lack of a fully integrated interdisciplinary workflow platform by providing a digital, 3D clear planning protocol for the interdisciplinary team. It gives them a clear vision of how to manage the case from start to finish successfully. It is versatile, logical and methodical and can be applied to any clinical situation where orthodontics is involved.
