Evaluation of marginal adaptation and internal fit of maxillary complex provisional bridge manufactured by two different methods: An In-vitro study

Aim: The purpose of this in vitro study was to evaluate if the marginal discrepancy and internal fit maxillary complex provisional bridge is improved by either 3D printing or CAD/CAM fabrication technique Methodology: In present a total sixteen samples (Eight each group) fabricated two methods using same STL file. Eight were from Telio CAD Subtractive CAM method (ARUM 5X- 400 Milling machine) (Control group), other HARZ Labs Dental Sand liquid resin additive (Anycubic photon S printer) (intervention group). All tested for gap Digital microscope silicon replica technique. Results: It found that regarding adaptation results; no statistically significant difference between the` methods.Conclusion: Marginal (Additive three dimentional milling) techniques within clinically acceptable ranges. Clinical implication: Both’ (Additive. and. subtractive) could be used
