Effect of margin thickness and cement gap on the fabrication and fit accuracy of additively manufactured crowns in definitive resins with different filler content

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate how commercially available composite resins in varying filler content affect the fabrication and fit accuracy (trueness and precision) of additively manufactured (AM) definitive crowns with different margin thickness and cement gaps by comparing them to subtractively manufactured (SM) polymer‐infiltrated ceramic crowns ...

Comparison of surface treatment protocols for a 3D‐printable resin for definitive crowns: Effects on surface roughness and bonding performance

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to compare the effects of surface treatment protocols on the surface roughness and shear bond strength (SBS) of a three‐dimensional (3D)‐printable resin for definitive crowns. Materials and Methods A 3D‐printable resin for definitive crowns (Saremco Print Crowntec) was used to produce 168 specimens (10 × 10 × 2 mm3 ...

Influence of occlusal thickness and aging on the fracture load of additively manufactured definitive crowns in different resins

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose The purpose of this in vitro study was to assess the effects of occlusal thickness and thermomechanical aging on the fracture load of additively manufactured (AM) definitive crowns made from resins with different compositions, compared with crowns subtractively manufactured (SM) from a polymer‐infiltrated ceramic network. Materials and
