Abstract
The use of 3D technology in orthodontics has increased recent years. 3D intra-oral
scanning, cone beam computed tomography (CBCT), 3D printing and computer-aided design
and computer-aided manufacturing (CAD/CAM) technology has been utilized to create
“personalized” orthodontic appliances. While technological improvements to orthodontic
appliances seem promising, do they truly improve treatment efficiency and/ or treatment
quality? This article will review currently available orthodontic appliances which
utilizes 3D technology such customized wires and CAD/CAM fabricated brackets. Customized
archwires are planned from 3D virtual setup and robotically bent. Studies have shown
a decrease in treatment time with the use of customized wires, however data on quality
of treatment results are conflicting. While this technology is fairly accurate for
mesial-distal tooth movements, it is less precise for crown tip and root torque. CAD/CAM
brackets were initially shown to be more effective and efficient when compared to
standard brackets, but a follow-up study showed no difference in the quality of treatment
of outcomes. The study also showed the majority of the reduction in treatment time
resulting from CAD/CAM brackets may be due to the indirect bonding process rather
than the personalized milled slots.
