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

Development and Validation of an AI‐Integrated System for Automated Fracture Detection and Pedicle Puncture Planning in Lumbar Osteoporotic Vertebral Compression Fractures Based on the Nine‐Grid Area Division Method

Orthopaedic Surgery, EarlyView.
This study developed a three‐module AI‐integrated software. Its effectiveness was verified, and it was confirmed to have certain transformation potential. ABSTRACT Objective The clinical application of the Nine‐grid Area Division Method for pedicle puncture in L‐OVCF is limited by high technical thresholds and low efficiency.

Low‐Cost and Detunable Wireless Resonator Glasses for Enhanced Eye MRI With Concurrent High‐Quality Whole‐Brain MRI

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 499-507, July 2026.
ABSTRACT Purpose To develop a wearable wireless resonator glasses design that enhances eye MRI signal‐to‐noise ratio (SNR) without compromising whole‐brain image quality at 7 T. Methods The device integrates two detunable LC loop resonators into a lightweight, 3D‐printed frame positioned near the eyes.

A re‐usable 3D‐printed training model for the endodontic management of dental trauma in immature teeth

International Endodontic Journal, Volume 59, Issue 6, Page 1188-1199, June 2026.
Abstract Aim To develop a 3D‐printed model enabling treatment simulation of trauma‐related endodontic and restorative procedures like revitalization or placement of an apical plug on teeth with incomplete root formation. Methodology To generate a realistic training model suitable for trauma‐related simulations, CT‐Data sets were segmented, combined ...
