Effect of substructure fabrication method and design on the fracture resistance properties of metal–ceramic restorations

Journal of Prosthodontics, EarlyView.
Abstract Purpose In metal–ceramic restorations, the substructure fabrication method and design may affect the prognosis of the prosthesis. This study evaluated and compared the fracture resistance of metal–ceramic restorations fabricated with different substructure fabrication methods using two different alloy powders and designs.

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 ...

Do the printing orientation angle and layer thickness influence the radiopacity of 3D‐printed dental resins?

Journal of Prosthodontics, EarlyView.
Abstract Purpose This in vitro study aimed to evaluate the effect of layer thickness, printing orientation angle, and resin type on the radiopacity of 3D‐printed dental resins. Materials and Methods Three dental 3D‐printed resins (VarseoSmile TriniQ, Crowntec, and Primeprint Temp) were investigated using two‐layer thicknesses (50 and 100 µm) and three ...

Comparative Analysis of Three Vertebral Screw Placement Directions in Anterior Thoracolumbar Fracture Surgery: A Finite Element Study

Orthopaedic Surgery, Volume 17, Issue 5, Page 1464-1477, May 2025.
This study compares the biomechanical effects of three anterior fixation systems in thoracolumbar surgery—HXTL, NHXTL, and Medtronic's CD Horizon ANTERIOR. Finite element analysis evaluates stress and displacement across vertebral bodies and support structures under varying load conditions. Results indicate the HXTL system minimizes nail–rod stress yet

The Anterolateral Transpedicular Transverse Process Screw Technique: Surgical Techniques, Biomechanical study and Preliminary Outcomes

Orthopaedic Surgery, EarlyView.
This study designed a novel anterolateral screw placement technique and, based on this, developed a new anterolateral fixation method. Imaging, biomechanical, and short‐term efficacy analyses revealed that the Anterolateral Transpedicular Transverse Process Screw (ALTTS) technique achieves a high success rate for L5 vertebral fixation (pedicle width ...

Evaluation of Ethyl Cellulose–Ethanol Ablation in a Human‐Sized 3D Construct of High‐Grade Cervical Dysplasia

Journal of Biomedical Materials Research Part A, Volume 114, Issue 7, July 2026.
ABSTRACT Current preclinical models for cervical dysplasia rely on animal systems that poorly mimic human anatomy. To address this and align with emerging initiatives to reduce animal experimentation, we developed a human‐sized, 3D in vitro model of high‐grade cervical dysplasia.
