Optimization of the Nonclinical Biological Evaluation of Medical Devices Using Toxicologic Pathology Best Practices

Advanced Healthcare Materials, Volume 15, Issue 3, 19 January 2026.
Nonclinical evaluation of biological responses to implanted medical devices and combination products in animals is required to predict possible outcomes and risks in patients. This paper describes globally accepted pathology “best practices” that 1) effectively address ISO standards and current regulatory guidance for medical device development and 2 ...

Printed Three-dimensional Anatomic Templates for Virtual Preoperative Planning Before Reconstruction of Old Pelvic Injuries: Initial Results

Chinese Medical Journal, 2015
Background: Old pelvis fractures are among the most challenging fractures to treat because of their complex anatomy, difficult-to-access surgical sites, and the relatively low incidence of such cases. Proper evaluation and surgical planning are necessary

Paranasal Volume Enhancement With Sticky Bone to Improve Nasolabial Fold Aesthetics in Orthognathic Surgery Patients: A Case Report

Case Reports in Dentistry, Volume 2026, Issue 1, 2026.
Purpose The paranasal region is a frequent source of aesthetic complaints in patients with dentofacial deformities, and soft tissue projection in this area does not always follow the skeletal movements achieved in orthognathic surgery. Sticky Bone—a particulate bone graft matrix agglutinated by platelet‐rich fibrin (PRF)—has an established role in ...

Osteosynthesis for Sagittal Splitting

All osteosynthesis techniques evolved from traumatology. There, the anatomically correct and stable positioning of fracture ends is the goal of treatment. In orthognathic surgery, however, the displacement of bone segments is the goal of treatment, which
