Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Purpose: The present study aimed to synthesize and characterize photocurable resin with lower cost to be used in DLP 3D printing to fabricate clear dental appliances like surgical guides and aligners. Materials and Methods: Mixture of acrylates of 1,10 decandiol diacrylate, pentaerythritol tetracrylate and isobornyl acrylare were mixed together and dissolve the photo initiator phenyl bis (2,4,6 trimethylbenzoyl) phosphine oxide and optical absorber 2,5-bis (tert-butyl-benzoxzzol-2-yl) thiophene by proper mixing for 30 mins at room temperature. Then experimental resin specimens were fabricated by DLP 3D printer 12 specimens were subjected to post curing for 15 mins and another 12 specimens were subjected to 25 mins post curing. Characterization was demonstrated by scanning electron microscope (SEM), thermo gravimetric analysis, and Fourier transform infrared (FTIR). Flexural strength was examined by three-point loading under universal testing machine, translucency was examined by spectrophotometer, and degree of convergence was calculated gravimetrically.Results: Results revealed successful fabrication of photocurable resin. The resin showed excellent surface finish under scanning electron microscope, thermally stable up to 500 °C. FTIR confirmed functional group matching with the target copolymer. Regarding flexural strength results, it was found that no significant difference between two groups (p ≥ 0.05) however translucency results revealed significant difference between two groups (p ≤ 0.05). Conclusion: Possible fabrication of photocurable resin to be used in DLP 3D printer.
