Definitive Obturator Fabrication for Partial Maxillectomy Patient

Case Reports in Dentistry, Volume 2020, Issue 1, 2020., 2020
Maxillectomy defects can result in oroantral communication that causes difficulty in mastication and deglutition, impaired speech, and facial disfigurement. The prosthodontist plays an important role in the rehabilitation of such defects with obturators.

Self‐Feeding Living Materials Enabled by Cell Responsive Glycogen Nanoparticles as Metabolic Batteries

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
Glycogen is introduced as a metabolic battery that offers local and cell‐triggered release of glucose. Glycogen can be stably encapsulated into hydrogel (Dex‐TA) microcapsules that allow for diffusion of glycogen‐degrading enzymes and nutrients.

PDGFRα+/Integrin α2+ Fibroblasts Orchestrate Tumor Budding in Oral Squamous Cell Carcinoma via Mechano‐Metabolic Symbiosis: E‐Cadherin/Integrin α2β1 Adhesion and Mitochondrial Transfer

Advanced Science, Volume 13, Issue 54, 28 September 2026.
PDGFA/PDGFRα signaling recruits CAFs to OSCC nests, and CAF‐OSCC contact drives tumor budding invasion. Mechanistically, heterotypic adhesion via E‐cadherin/integrin α2β1 activates YAP signaling in OSCC cells, inducing EMT. Concurrently, CAFs transfer mitochondria through TNTs, supplying ATP to fuel invasion.

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models

Advanced Materials Technologies, Volume 11, Issue 13, 8 July 2026.
Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.
