Radiation dose optimization in coronary CT angiography clinical application of absolute phase gating in patients with atrial fibrillation. [PDF]

J Appl Clin Med Phys
Abstract Background Atrial fibrillation (AF) poses significant challenges for coronary CT angiography (CCTA) due to R‐R interval variability, often necessitating high radiation dose protocols. Absolute phase gating, which uses fixed millisecond delays rather than percentage‐based cardiac cycle timing, may optimize image quality while reducing radiation

Influence of the post‐processing protocol on a biocompatible 3D‐printed resin

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study aimed to evaluate the cytotoxicity of a biocompatible 3D‐printed resin material for occlusal devices after post‐processing with two different high‐intensity UV‐polymerization devices and two rinsing solvents, in the presence of human gingival fibroblasts (HGFs).

Peri‐implant tissue definition and registration with a 3D‐printed emergence profile former on titanium stock healing abutment: A dental technique and clinical report

Journal of Prosthodontics, EarlyView.
Abstract Recent focus has shifted toward refining the soft tissue emergence profile to enhance aesthetics, support peri‐implant health, and ensure long‐term success. Traditionally, titanium stock healing abutments or chairside‐customized abutments were used to shape peri‐implant tissues and develop the emergence profile for implant‐supported prostheses.
