The Application of a 3-Dimensional Printing Technique in Refining the Orthodontic Trans-Palatal Arch

The aim of this article was to describe the process designing and manufacturing 3D TPAs discuss some clinical cases in which were used. Digital models acquired by scanning casts, PVS impressions or dentitions directly. data a common STL format used for computer design that follows. Then, instructions sent printer fabrication. Finally, manual polishing should be performed. Seven assist orthodontic treatment presented discussed. demonstrated TPA simple, convenient appliance patient doctor, thus, might more cleansable. could designed different types based on needs each case. application expanded, but trials are necessary verify advantages reported here.
