Implementing 3D‐printed indexing devices and contemporary scanning techniques for complete‐arch implant‐supported rehabilitations: A clinical case report

Journal of Prosthodontics, EarlyView.
Abstract A sixty‐eight‐year‐old male presented to the dental clinic seeking a complete mouth rehabilitation. He exhibited generalized dental caries, dental staining, cervical lesions, fremitus, and anterior wear. After declining tooth‐retaining options, he elected full‐mouth extractions with immediately loaded implant‐supported prostheses.

MODELING OF PHOTOPOLYMER CURING

PNRPU Mechanics Bulletin
The paper considers the process of curing a photopolymer material. The effect of light on a photopolymer material triggers a reaction that leads to the conversion of polymer chains, which leads to the release of heat and an increase of temperature, solidification or an increase of stiffness of the material, and is also accompanied by a volumetric ...

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 ...

Influence of degree of conversion on the cytotoxicity of 3D‐printed denture base resins. A scoping review

Journal of Prosthodontics, EarlyView.
Abstract Purpose Evidence regarding the cytotoxicity of 3D‐printed denture base resins and the role of degree of conversion remains limited and heterogeneous. Therefore, this scoping review aimed to map existing in vitro evidence and explore how degree of conversion and post‐processing factors are reported in relation to biological outcomes.

Effect of access‐opening closure materials on fluid‐related mass gain and volumetric change in three‐dimensionally printed closed‐hollow obturator specimens

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate how denture base resin and access‐opening closure material affect fluid‐related mass gain and micro‐computed tomography‐derived volumetric changes in three‐dimensionally printed closed‐hollow obturator specimens. Materials and Methods Specimens were printed from NextDent Denture 3D+ or Apex Base resin.
