Marginal gap of printed, milled, and heat‐pressed two‐piece polyetheretherketone abutments before and after thermal cycling, and their pull‐off bond strength after thermal cycling

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose To evaluate the marginal gap of two‐piece polyetheretherketone (PEEK) abutments fabricated with different methods, before and after thermal cycling, while also focusing on their pull‐off bond strength. Materials and Methods A two‐piece abutment was virtually designed after digitizing a titanium‐base (Ti‐base) abutment.

Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

open access: yesJournal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

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

open access: yesJournal 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 ...
