Comparative Radiopacity of Additively Manufactured Permanent and Temporary Resins and Conventional Resin‐Based Composites

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This study aimed to evaluate whether radiopacity differs among additively manufactured permanent resins, temporary resins, and conventional resin‐based composites at clinically relevant thicknesses. Materials and Methods Eight dental materials were evaluated and categorized into four groups: additively manufactured permanent resins ...

Do the printing orientation angle and layer thickness influence the radiopacity of 3D‐printed dental resins?

Journal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effect of layer thickness, printing orientation angle, and resin type on the radiopacity of 3D‐printed dental resins. Materials and Methods Three dental 3D‐printed resins (VarseoSmile TriniQ, Crowntec, and Primeprint Temp) were investigated using two‐layer thicknesses (50 and 100 µm) and three ...

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

Journal 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 ...

A Dual Cell‐Line Molecular Platform to Assess Sub‐Threshold Biocompatibility: Application to Processed Orthodontic Clears Aligners

Orthodontics &Craniofacial Research, EarlyView.
ABSTRACT Objective Traditional biocompatibility assessments primarily address cytotoxicity and bulk material properties but often overlook molecular responses that occur below toxicity thresholds. Detecting these subtle effects is crucial for materials intended for prolonged contact with human tissues.

Inverse Vulcanization Through Epoxide Chemistry: A Low Temperature Non‐Olefin Route to Sulfur‐Rich Polymer Networks

Angewandte Chemie, Volume 138, Issue 33, 10 August 2026.
Epoxide monomers undergo base‐catalyzed ring‐opening copolymerization with elemental sulfur to afford sulfur‐rich polymers under mild conditions. The resulting materials exhibit excellent mechanical performance, strong adhesion (up to 10 MPa on stainless steel), and outstanding reprocessability.
