Development of patient-specific orbital floor implants made of shape memory alloys

, 2016
Fractures of the orbit may be occurring by blunt trauma to the eye, for example, in traffic, work and sports accidents. The treatment of orbital floor defects is often done surgically by use of implants from rigid materials such as titanium, which are ...

Intranasal migration of a 35-year-old orbital plate presenting as unilateral epiphora

Otolaryngology Case Reports, 2018
Migration of orbital implants is a rare complication, which can present many years after initial placement and with a wide variety of symptoms. We describe a case of the oldest nasal foreign body in the literature in a 69-year-old male who presented with

A Literature Review of Rapid Prototyping and Patient Specific Implants for the Treatment of Orbital Fractures

, 2021
Post-traumatic reconstruction of the orbit can pose a challenge due to inherent intraoperative problems. Intra-orbital adipose tissue is difficult to manipulate and retract making visualization of the posterior orbital contents difficult.

3D‐Printed Titanium Gyroid Scaffold Structure Integrated With Tough Hybrid Materials for Cartilage Replacement

Advanced Engineering Materials, EarlyView.
This study proposes a potential device design for joint cartilage replacement. Silica‐polytetrahydrofuran (SiO2‐PolyTHF) hybrids with customizable mechanical properties were developed to mimic the characteristics of a natural meniscus. These were synthesized through a two‐pot sol–gel hybrid process.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Patient specific implants in orbital reconstruction: A pilot study

American Journal of Ophthalmology Case Reports, 2021
Purpose: Successful repair of the orbital skeleton restores function and cosmesis by normalizing globe position and allowing full motility of the extraocular muscles. Routine repairs are successful with standard implants.
