A dental suction assisting device includes an upper molar seat located at an upper portion of a body and having anti-separation protrusions and a space for allowing seating of upper molars, a lower molar seat located at a lower portion of the body and having anti-separation protrusions and a space for allowing seating of lower molars, a fastening portion having an insertion hole and a through-hole and allowing fastening of a suction tube, a suction port having a first suction hole and allowing secretions in an oral cavity to be sucked through the suction tube, a leg formed at each side of the lower molar seat, configured such that the respective legs are brought into intimate contact with opposite side surfaces of the lower molars and having partitions, and a wing extending from the leg, and seated between the lower molars and skin in the oral cavity.

A lip retractor includes a first curved portion having a recess running along an outer surface, a second curved portion having a recess running along an outer surface, the second curved portion opposing the first curved portion, an arm connecting the first curved portion to the second curved portion, an interior suction chamber configured at least partially through the first and second curved portions and the arm, and a first port on an inner surface of the first curved portion, a second port on an inner surface of the second curved portion, and an evacuation connection port connected to the arm, wherein the first port, the second port and the evacuation connection port are in fluid communication with the interior suction chamber.

The present disclosure is directed to improved multi-suction dental devices, assemblies, systems and methods and of using the same. The multi-suction dental devices can be configured to suction both liquids and aerosols during dental procedures. Each multi-suction dental device can comprise at least one low-volume evacuation (LVE) suction pathway and at least one high-volume evacuation (HVE) suction pathway.

An article of manufacture for providing a dental droplet extraction device is disclosed. The device is created around a large collection basin having a funnel-like opening at its top. An exit port is located at the bottom of the large collection basin. The exit port is connected to a high-volume dental line to provide negative pressure that suctions all of the aerosolized droplets created within the patient's mouth while receiving treatment. The removed particles may be trapped in a filter located in the dental suction lines.

The invention is about a stomatological negative pressure mouth gag and its usage, which falls into the scope of stomatological technologies. The upper and lower wings of the mouth gag is connected by a thin-walled tube. The inner wall of the thin-walled tube is in direct contact with the lips, while its outer wall is exposed to the oral cavity. There are holes or slots evenly distributed on the outer wall of the thin-walled tube mounted along the arc-shaped lip holders. The left and right lip holders are connected by a negative pressure catheter between them. The thin-walled tubes on the left and right sides join with the negative pressure catheter and form a complete structure with it.

A system and a method for a hands-free dental suction device includes a contoured tube that may be connected to dental suction lines commonly found in dental operatories. One specific embodiment includes features which allow the hands-free suction device to be attached to a dental lip/cheek retractor, and/or to the patient's lip, in a manner that is both comfortable for the patient and allows convenient, unobscured access to the patient's oral cavity. One potential benefit of the device is the collection and removal of dangerous aerosols generated during dental procedures which may be responsible for spreading disease.
