3D-printed orthodontic brackets - proof of concept.

Area of Science:

• Orthodontics
• Biomaterials Engineering
• Digital Dentistry

Background:

• Traditional orthodontic treatment relies on preprogrammed, mass-produced brackets (metal or ceramic).
• A fully digital workflow offers potential for enhanced customization and precision in orthodontic procedures.

Purpose of the Study:

• To evaluate the clinical applicability of a fully digital workflow for fabricating individually designed and 3D-printed orthodontic brackets.
• To assess the integration of computer-aided design (CAD) and 3D printing in orthodontic treatment.

Main Methods:

• Custom edgewise brackets were designed using CAD software based on intraoral scan data.
• A digital positioning guide and individualized arch form template were created for precise bracket placement.
• Brackets, positioning guides, and retainer splints were fabricated using Digital Light Processing (DLP) 3D printing.
• Individually pre-bent archwires were produced using the digital template.

Main Results:

• The study successfully demonstrated the principle of performing orthodontic treatment with an individualized 3D-printed bracket system.
• The proposed fully digital workflow was shown to be feasible for clinical implementation.
• Technical aspects, challenges, and future directions of this digital workflow were discussed.

Conclusions:

• A fully digital workflow integrating CAD and 3D printing is a viable approach for producing individualized orthodontic brackets.
• This method allows for precise customization, potentially improving treatment efficiency and outcomes.
• Further research and development are warranted to optimize the system and address encountered challenges.
