Abstract

A dental aerosol containment system includes a dental tool having an end effector adapted to interact with a maxillofacial structure, and a distal end opposing the end effector, the interaction having an aerosol or particulate debris associated therewith. A shroud extends about the dental tool and defines an opening having the end effector extending therethrough. The shroud being arranged to deflect the aerosol or particulate debris away from the distal end toward the end effector. Alternately, an opening of a nozzle is arranged adjacent to the end effector so as to allow the end effector to interact with the maxillofacial structure. The nozzle is arranged in fluid communication with the suction source such that the suction is imparted through the opening of the nozzle to draw the aerosol or particulate debris associated with the interaction between the end effector and the maxillofacial structure into the nozzle.

Description

Dental Aerosol Containment System

The present application relates to dental systems, and more particularly, to containment devices for containing aerosol or particulate debris generated during dental procedures on individuals.

Disease is often spread in the workplace, and the exposure risk is significantly higher for dental professionals using powered instruments such as ultrasonics, air polishers, and drills. Bacteria and viruses can spread rapidly through splashes, aerosols, and particulate debris from these types of handling. That is, for example, aerosols, particulate debris, and spatter produced by ultrasonic, drilling, and air polishing processes can contain saliva, blood, bacteria, and pathogens. Even though particulate debris and spatter can end up on surfaces immediately surrounding the treatment area, aerosol particles can remain in the environment for an hour or more once airborne. This is a risk for the spread of, for example, common cold and influenza viruses, herpes viruses, pathogenic Streptococcus or Staphylococcus, Severe Acute Respiratory Syndrome (SARS), and Tuberculosis (TB), and is a major risk for dental professionals.

Thus, there is a need for a dental aerosol containment system for effectively regulating the spread of contamination and contamination by limiting the spread of dental aerosol and particulate debris resulting from a maxillofacial procedure, which addresses the limitations of prior art devices. limit.
