The face shields that are available from R-Dent include a 3D printed headband, clear plastic shield, and an elastic head strap. The plastic shield can be reused after being thoroughly sanitized.
3D Printed Headband
The 3D printed headband uses a tan material (DPR 10) in a solid, open gap design. The clear plastic shield can be snapped onto the headband via an easy-to-use, interlocking component.
Clear Plastic Shield
The clear plastic shield is made of a thin, polyester sheet. It is attached to the 3D printed headband. The exact product offering may differ due to the availability of the plastic sheets.
The shield can be reused after thorough cleaning in between patients. While this recommendation is made based on the feedback from physicians and infection control groups, every hospital bears the responsibility to determine the appropriate use/reuse protocols for all PPE based on a review of the product by their own infection control group.
