Abstract
ABSTRACT 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.
