Development of a Gingiva Model With Periosteum for Dental Students Using 3D Printing Compared to Knowledge‐Related Models

open access: yesEuropean Journal of Dental Education, EarlyView.
ABSTRACT Introduction An adequate gingiva model for dental students has special requirements, such as strength, flexibility and a periosteum. As there is a lack of available models, the aim of this study was to develop a new and sufficient gingiva model that fits students' needs.

Dual asymmetric centrifugation to prepare cosmetic emulsions and creams: Physico‐chemical and energy considerations

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Dual asymmetric centrifugation (DAC) enables the preparation of stable cosmetic emulsions and structured creams with physicochemical, rheological and textural properties comparable to those of conventional processes. At larger scales, DAC also offers competitive energy efficiency by avoiding heating steps, supporting more sustainable cosmetic ...

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.
