A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

International Endodontic Journal, EarlyView.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...

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

Journal 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.
