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.

Bond strength enhancement for additively manufactured zirconia: Micro‐retentive design approach

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effect of digitally designed micro‐retention features on the bond strength of additively manufactured (AM) zirconia copings. Materials and Methods Sixty titanium base abutments (NobelParallel, NobelBiocare), pretreated with 50 µm alumina particles were divided into four groups (n = 15 per group); one group with ...

Effect of material, prosthesis height, and aging on the fracture strength of additively and subtractively manufactured implant‐supported cantilevered prostheses

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the inherent and after cyclic loading fracture strength of implant‐supported cantilevered fixed prostheses fabricated from recently introduced additively manufactured (AM) and subtractively manufactured (SM) materials, considering variations in prosthesis height.

Employing a Hysteresis Approach to Analyze Shifts in Tree Physiological Thresholds in Response to Drought

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought‐induced tree mortality underscores the need for improved physiological models to predict tree responses to water stress. We employed a hysteresis modelling approach analyzing diel water absorption and desorption cycles to understand drought‐induced shifts in physiological thresholds.

Etiology, pathogenesis and treatment of peri‐implantitis: A European perspective

Periodontology 2000, EarlyView.
Abstract Peri‐implantitis is a plaque‐associated pathological condition occurring in tissues around dental implants. It is characterized by inflammation in the peri‐implant mucosa and progressive loss of supporting bone. Over the last 30 years, peri‐implantitis has become a major disease burden in dentistry.
