Accuracy of soy-based resins for dental 3D printing
Objectives:
To verify the accuracy of soy-based resins for dental three-dimensional (3D) printing.
Materials And Methods:
After conducting a power analysis, models of 10 consecutively treated patients were produced from four different resins using a dental 3D printer. Two of these resins were soy based and therefore biodegradable. These 20 models were measured manually with a caliper as well as digitally by software and compared based on measurement parameters in all three spatial axes.
Results:
No statistically significant differences were found between the four different resins or between the manual and digital measurements.
Conclusions:
Soy-based resin seems to be a suitable material for orthodontic 3D printing and is a more environmentally friendly alternative to conventional dental resins. Digital model analysis seems to produce comparable results to manual measurement.
