Protect your patients and your family.

While performing standard dentistry and hygienist procedures, such as drilling or ultrasonic teeth cleaning, pathogen-infested blood & saliva aerosols are released into the dental office environment. These stay airborne for two hours and can penetrate face masks, becoming a source of infections and cross-contamination among dental professionals and patients.

Inspired by space technology and supported by the European Space Agency and the European Institute of Technology, the OBF® is a simple device that, once connected to the high-volume evacuation system available in any dental chair, provides an effective barrier that isolates the oral cavity from the dental office environment.

OBF® is a patented original development by Astradentium which has been subjected to clinical studies to confirm its unparalleled protection efficacy. Results published in leading scientific peer-reviewed journals. For your own safety, disregard unlicensed imitations.


Avoid cross-infections among patients, dentists, oral surgeons, or hygienists.

Avoid medical complications, like implant failures, due to opportunistic infections you want to show.
