Do the Various Indirect Bonding Techniques Provide the Same Accuracy for Orthodontic Bracket Placement? (Randomized...

Area of Science:

• Orthodontics
• Biomaterials Engineering
• Digital Dentistry

Background:

• Precise bracket placement is essential for efficient orthodontic treatment and achieving ideal occlusion.
• This study evaluates the accuracy of manual and digital bracket positioning using computer-aided design and computer-aided manufacturing (CAD/CAM) jigs, 3D-printed indirect bonding trays (IBT), and vacuum-formed thermoplastic IBT.

Purpose of the Study:

• To assess the accuracy of manual and digital bracket positioning techniques.
• To compare the precision of different types of indirect bonding trays (IBT) in transferring planned bracket positions.

Main Methods:

• Dental arch scans from 30 patients were used for virtual setup and bracket positioning.
• Digital positioning was performed using Insignia™ and 3D Maestro® software; manual positioning used the Ray Set® device.
• IBTs were fabricated using CAD/CAM, 3D printing, and vacuum-forming; accuracy was evaluated via 3D digital superimposition and statistical analysis.

Main Results:

• Positional discrepancies were observed but remained within clinically acceptable limits.
• All tested indirect bonding tray types demonstrated accepted precision in both linear and angular measurements.

Conclusions:

• Indirect bonding trays effectively translate planned bracket positions from digital and manual techniques to the teeth.
• The error rate is comparable across all types of indirect bonding trays evaluated.
