Abstract: An extraoral suction device for managing aerosol emissions during dental procedures includes: a conduit; an adapter in fluid communication with the conduit; and a mount for mounting the extraoral suction device to a dental chair. The adapter is configured to be placed in fluid communication with a vacuum source to provide suction to the extraoral suction device. The conduit can be selectively manipulated to assume and maintain a position without support from an individual or designated support structure. A dental professional can thus manipulate the conduit to maintain a position in front of the oral cavity of a patient seated in the dental chair to direct aerosols emitted from the oral cavity of the patient into the extraoral suction device instead of the surrounding environment. The extraoral suction device can thus be combined with a dental chair and vacuum source to provide an improved dental chair system for dental procedures.
