Systems and methods to reduce spatter and aerosol during dental procedures

a technology of aerosol and spatter, applied in the field of dental procedures, can solve the problems of contaminating practitioners, equipment, any exposed surface in the room, and none of them working effectively to remove spatter and aerosol, and achieve the effects of reducing the ejection velocity of spatter, facilitating implementation, and capturing the effect of spatter

AI Technical Summary

Benefits of technology

The patent text describes an improved apparatus and methods to remove contaminants during oral procedures. The new device is easy to use, reduces the ejection velocity of spatter and aerosols, provides a structure that will not interfere with the practitioner's access to the oral cavity, acts as a cheek retractor, and also serves as an oral suction device. The methodology includes larger collection cups and negative airflow to slow aerosols and better capture spatter.

Problems solved by technology

Once spatter and aerosol get into space surrounding the patient in the treatment room, it will contaminate practitioners, equipment, any exposed surfaces in that room.
However, none of them work effectively to remove spatter and aerosol as they exit the mouth before they can contaminate the surrounding area.

Embodiment Construction

[0017]With reference now to the drawings, a preferred embodiment of the spatter control system is herein described. It should be noted that the articles “a”, “an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.

[0018]FIG. 1 depicts a pattern of spatter and aerosol ejected from a human mouth during the treatment where 101 is a human head and 102 is opening of human mouth. The three-dimensional ejection pattern of spatter and aerosol 105 has a cone shape with an emitting angle θ1, relative to human face. The angle θ1 changes around the edge of the mouth, depending on the cutting position of the HP and any intra-oral suction device used during the procedure. Intra-oral suction devices, like a high-volume evacuator (“HVE”) or shields, may change the ejection pattern around the mouth; but they will not be able to totally contain spatter and aerosol since the ejection speed of spatter and aerosol is so high. Regardless, the...

Abstract

A method and apparatus to remove spatter and aerosol during dental procedures with may feature a deflector mounted upon a mouthpiece structure that directs emitted aerosols and spatter into a narrower cone for easier collection and evacuation. The mouthpiece may also serve as a cheek retractor and as an oral suction apparatus during a procedure. Increasing collection cup size and providing negative airflow will also improve the control of spatter and aerosol.

CROSS-REFERENCES TO RELATED APPLICATIONS[0001]This Application claims priority as a non-provisional perfection of prior filed U.S. Application No. 63 / 087,699, filed Oct. 5, 2020, and incorporates the same by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to the field of dentistry and more particularly relates to a method and apparatus to control spatter and aerosols created in dental procedures.BACKGROUND OF THE INVENTION[0003]One of the most prevalent tools used in dentistry is the high-speed handpiece “HP”). The HP has become essential to dental practice as it is the base for many tools used in dental procedures. The HP is a high-speed rotary driver that powers many different tools used in dentistry. In use, the practitioner merely changes the head on the handpiece use a different tool of choice. Currently an HP can operate in the range of 200,000 to 1,000,000 revolution per minute (RPM) depending on type of HP, with air turbines reachin...
