Abstract:

 

Purpose
This  study  aims  to  compare  the  accuracies  of  full-arch  models  printed  by  two  different 3D printing technologies.
Materials and Methods
A  mandibular  horseshoe-shaped  master  model  was  designed  with  RapidForm  XOR2 software The master model was printed 10 times with 3D printers using direct light  processing  (DLP)  and  PolyJet  technology  (n=20).  The  printed  models  were  then  scanned  with  an  industrial  scanner  and  saved  in  STL  file.  All  digital  models  superimposed  with  the  master  model  STL  file  and  comparison  of  the  trueness  was  performed  using  Geomagic  Control  3D  analysis  software.  The  precision  was  calculated by superimposing combinations of the 10 data sets in each group.
Results
The trueness of printed models was 46 μm for the DLP printer and 51 μm for PolyJet printer;  however,  this  difference  was  not  statistically  significant  (p=0.155).  The  precision  of  printed  models  was  43  μm  for  the  DLP  printer  and  54  μm  for  PolyJet  printer.  DLP  printed  models  were  more  precise  than  the  PolyJet  printed  models  (p<0.001).
Conclusion
The  3D  printing  technologies  showed  significant  differences  in  the  trueness  of  full-arch  measurements.  Although  DLP  printed  models  had  better  trueness  than  PolyJet printed models, all of the 3D printed models were clinically acceptable and might be used for the production of fixed restorations.
