Those scores of eye tiredness and eye heaviness were significantly longer before and after the visual task with tablet candy ( = 0.013 and = 0.025, respectively) but not with chewing gum. The changes of subjective accommodation were significantly lower after the visual task between chewing gum and candy ( = 0.043). There were significant differences among each age group (20 s vs. 30 s, = 0.594; 20 s vs. 40 s, = 0.002; 20 s vs. 50 s, = 0.002). After reading, the changes of spherical equivalent refraction did not indicate a shift toward myopia ( = 0.267). In the RBUT, there were no significant differences between the samples ( = 0.680). Chewing gum helps improve the ability of the eye to focus, especially in young adults.

However, the deformation of prostheses resulting from the postcuring process has not been fully investigated. The purpose of this study was to evaluate the effects of different postcuring methods on the fit and dimensional accuracy of 3D-printed full-arch polymeric fixed prostheses. A study stone model with four prosthetic implant abutments was prepared. A full-arch fixed dental prosthesis was designed, and the design was transferred to dental computer-aided manufacturing (CAM) software in which supports were designed to the surface of the prosthesis design for 3D printing. Using a biocompatible photopolymer and a stereolithography apparatus 3D printer, polymeric prostheses were produced (N = 21). In postcuring, the printed prostheses were polymerized in three different ways the prosthesis alone, the prosthesis with supports, or the prosthesis on a stone model. Geometric
