The success of orthodontic treatment depends greatly on how accurate the orthodontic brackets are, especially the slot where the wire fits. Even small errors in bracket dimensions can affect tooth movement and prolong treatment time.
This study aimed to find out whether orthodontic brackets made using 3D-printing technology are accurate enough for clinical use, and how they compare with conventional brackets.

The authors reviewed several laboratory studies that measured the dimensions of 3D-printed brackets. The results showed that 3D-printed brackets generally have clinically acceptable accuracy and are often more precise than traditional brackets.
However, the surface of 3D-printed brackets was sometimes rougher, meaning additional finishing or polishing may be needed.

Overall, the findings suggest that 3D printing is a promising method for producing orthodontic brackets, but optimal results depend on the printing technique and proper post-processing.
