Summary
This study introduces a precise digital workflow for indirect orthodontic bonding using Cone Beam Computed Tomography (CBCT) and CAD-CAM technology. This method ensures accurate bracket placement for improved orthodontic treatment outcomes.
Area of Science:
- Dentistry
- Orthodontics
- Digital Imaging
Background:
- Successful orthodontic treatment relies on accurate diagnosis and meticulous treatment planning.
- Current methods for indirect bonding can be prone to errors in appliance positioning.
Purpose of the Study:
- To present a reproducible and precise digital method for indirect orthodontic bonding.
- To leverage Cone Beam Computed Tomography (CBCT) images and CAD-CAM processes for enhanced accuracy.
Main Methods:
- A 37-year-old female patient's orthodontic treatment case was selected.
- Digital models were created from intraoral scans and CBCT data, processed using specialized software (Maestro 3D, MIMICS, Meshmixer).
- A virtual setup was performed, followed by bracket positioning on the 3D model and creation of a digital transfer template for indirect bonding.
Main Results:
- The developed digital workflow generates a realistic, three-dimensional coronal-root model of dental arches.
- This model facilitates indirect orthodontic bonding, minimizing errors in the expression of appliance information (1st, 2nd, and 3rd order).
Conclusions:
- Advancements in oral scanning and 3D printing enable easy and reproducible ideal positioning of orthodontic brackets.
- This digital approach enhances the precision of indirect bonding procedures.
