Assessing the influence of titanium dioxide nanotubes incorporation on thermal and thermomechanical characteristics of 3D‐printed denture base resin

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aims to evaluate the effects of adding titanium dioxide (TiO2) nanotubes (NTs) to three‐dimensional (3D) printed denture base resin on the thermal and thermomechanical properties, which have high clinical relevance. Materials and Methods TiO2 NTs with dimensions of 30–70 nm in diameter and 2–4 µm in length were added to the ...

Study of influence of ACPA in PVA/AA photopolymer for holographic reflection gratings [PDF]

, 2014
This work pretends to optimize the standard composition of the PVA/Acrylamide photopolymer, changing its composition in order to improve its spatial resolution. To do this, a chain transfer agent, 4,4'-azobis (4-cyanopentanoic acid) (ACPA) was introduced

Accuracy of face scan‐based virtual facebow records: A comparison between two registration methods

Journal of Prosthodontics, EarlyView.
Abstract Purpose Accurate maxillary positioning is critical in digital prosthodontics, particularly when transferring the spatial relationship of the maxilla to a virtual articulator. This study aimed to compare the accuracy of the two most common registration methods, three‐dimensional (3D) match and UV (landmark‐based point‐pair registration) match ...

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 ...
