| Criteria | Description |
| P (problem or population) | P (problem or population) comprised specimens of dental resins printed 3D devices. |
| I (intervention) | I (intervention), assessment of the properties of 3D-printed dental resins. Including mechanical properties, biocompatibility, cell viability, surface characteristics, and other properties in in-vitro or in-vivo studies. |
| C (comparison) | C (comparison), was determined as milling/subtractive manufacturing procedures or conventional procedures. Comparisons of different dental resins printed 3D after the application of the manufacturing process variations, such as post-curing temperatures, duration and intensity. |
| O (outcome) | O (outcome), corresponded to the assessment of all characteristics and properties of the polymer printed dental devices Studies included in the review reported on these outcomes in either in-vitro laboratory settings or in-vivo biological contexts. |
