Finite Element Simulation of NiTi Umbrella-Shaped Implant Used on Femoral Head under Different Loadings

Bioengineering, 2017
In this study, an umbrella-shaped device that is used for osteonecrosis treatment is simulated. The femoral head is subjected to various complex loadings as a result of a person’s daily movements. Implant devices used in the body are made of shape memory

Dental Implant Osseointegration Following Mandibular Augmentation Using 3D Printed Hydroxyapatite Blocks. An Experimental In Vivo Study

Clinical Oral Implants Research, Volume 37, Issue 2, Page 101-113, February 2026.
ABSTRACT Objective To evaluate the use and osseointegration of dental implants in combination with 3D‐printed hydroxyapatite (3DHA) blocks featuring gyroid porosity for large mandibular bone augmentation. Methods Mandibular lateral bone augmentation with gyroid‐3DHA blocks was performed bilaterally on four female Göttingen minipigs. After 8 or 12 weeks

Supervised Machine Learning to Predict Drilling Temperature of Bone

Applied Sciences
Surgeons face a significant challenge due to the heat generated during drilling, as excessive temperatures at the bone–tool interface can lead to irreversible damage to the regenerative soft tissue and result in thermal osteonecrosis.

Denosumab Regulates Titanium Particles‐Induced Macrophages Inflammation and Osteolysis by Targeting the ST18/PARP1 Interaction

Orthopaedic Surgery, Volume 18, Issue 2, Page 322-334, February 2026.
The schematic diagram of the role of Denosumab and ST18/PARP1 axis in the prevention of prosthesis‐related AL. Denosumab regulates TiPs‐induced macrophage activation and osteolysis through the NF‐κB pathway and M1 polarization, with ST18 acting as a key mediator.

Thermal damage done to bone by burring and sawing with and without irrigation in knee joint replacement

, 2014
Orthopaedic tools which resect bone in procedures such as total knee replacement (TKR) generate heat, causing a temperature rise at the resected surface.

Adjuvant pharmacological strategies for the musculoskeletal system during long‐term space missions

British Journal of Clinical Pharmacology, Volume 92, Issue 1, Page 11-23, January 2026.
Abstract Despite 2 h of daily exercise training, muscle wasting and bone loss are still present after 6‐month missions to the international space station. Some crew members lose bone much faster than others. In preparation for missions to the Moon and Mars, space agencies are therefore reviewing their countermeasure portfolios.

Hip Hemi‐Resurfacing With 3D‐Printed Titanium Mini‐Prosthesis: A Case Report

Case Reports in Orthopedics, Volume 2026, Issue 1, 2026.
Background Hip degeneration in young patients poses a significant clinical challenge, especially when the acetabulum remains intact. Total hip arthroplasty (THA) is often postponed in these patients due to concerns about implant longevity and multiple revisions. Joint‐preserving alternatives are therefore crucial.

An integrated analysis of thermal response and surface integrity of bone drilling with zirconia drills

Journal of King Saud University: Engineering Sciences
Bone drilling is an important process in orthopaedic and dental surgery, where excessive heat and poor surface integrity can lead to thermal osteonecrosis and loss of implant stability.
