Comparison of flexural strength, marginal gap, and internal fit of milled and 3D-printed crown materials.

The purpose of this study was to compare the flexural strength, Weibull modulus (reliability), marginal gap, and internal fit (internal gap) of 4 materials for milling or 3-dimensional (3D) printing of definitive and provisional crowns: IPS e.max CAD (IEC), Paradigm MZ100 Block (PMB), Permanent Crown Resin (PCR), and Temporary CB Resin (TCR). Flexural strength was tested by subjecting sectioned milling blocks (IEC and PMB) or 3D-printed bars (PCR and TCR) to a 3-point bending test in a universal testing machine (n = 15 per material).

Comparing the Accuracy of Conventional Gypsum and 3D-Printed Dental Casts Using Three-Dimensional Analysis.

Introduction: Dental impressions and casts play a critical role in dental care, facilitating diagnoses and the fabrication of prostheses. Traditional methods of fabrication involve elastomeric materials that are more prone to errors and patient discomfort. Digital advancements offer promising alternatives, yet their accuracy and applicability to military dentistry remain under-explored.

Large-bore Aspiration Thrombectomy with the FlowTriever System for the Treatment of Pulmonary Embolism: A Large Single-Center Retrospective Analysis.

Purpose: Evaluate the outcomes of patients undergoing large-bore aspiration thrombectomy for the treatment of pulmonary embolism at a large university medical center.

Materials And Methods: All patients treated for pulmonary embolism with the FlowTriever System (Inari Medical, Irvine, CA) between September 2019 and January 2023 were retrospectively analyzed. The primary safety and effectiveness outcomes included 7- and 30-day all-cause mortality, major bleeding, procedure-associated clinical decompensation, pulmonary vascular or cardiac injury, and pulmonary artery pressure reduction.
