A dental mouthpiece can provide multiple features that can benefit both the patient and the doctor. The mouthpiece can take a generally flat configuration when not in use and may be resiliently folded into a C-shape for insertion into the patient's mouth. In some embodiments, the frame may be rigid or semi-rigid. The mouthpiece may provide retraction, suction ability, tongue control, airway and throat protection and a bite block in a single disposable or reusable device.

A disposable dental aerosol device has a tube having a tip end having a tip having a tip opening, a valve receiving end having a rear end opening, and an aerosol directing device having an aerosol collecting funnel, a first vane, a second vane, a first aerosol capturing port formed between the first vane and the second vane, and a second aerosol capturing port formed between the second vane and the first vane.

A disposable dental aerosol device has a body having a tip receiving end, a valve receiving end, a central lumen formed between the tip receiving end and the valve receiving end, and a funnel at the tip receiving end, an aerosol capturing port having an aerosol capturing port lumen, and an aerosol capturing port entrance opening formed in the funnel and an aerosol port exit opening formed in the central lumen with the aerosol capturing port lumen spanning between the aerosol capturing port entrance opening and the aerosol capturing port exit opening.

Dental instrument assemblies (e.g., mouth pieces, bite blocks, vacuum dental mirrors, illuminated dental mirrors, illuminated dental wedges, trans-illumination dental instrument, illuminated dental bite blocks, etc.) are provided. The dental instrument assemblies may be adapted to be periodically sterilized. The dental instrument assemblies may include a magnetically energetic fiber optic coupler. The magnetically energetic fiber optic coupler may be configured to allow dental instrument adapter to rotate with respect to an associated fiber optic cable that is removably connected to the magnetically energetic fiber optic coupler. The dental instrument assemblies may include a fiber optic material that is encapsulated.

A siphoning device suited for automatically removing fluid/blood from a surgical site is described, having a length of sterile flexible tubing that is configurable into a loop, the tubing having a first open end, a second open end, and a central portion. A plurality of holes punctuate the circumference of either the first open end or the central portion of the loop, the one or more sets of holes being distributed along a longitudinal direction of the tubing. A sterile absorbent covering encompasses the one or more sets of the plurality of holes, the covering being permeable to bodily fluids. The siphoning device is connected to a vacuum system that generates a negative pressure, causing fluids that have accumulated in the absorbent covering to be withdrawn into the vacuum system. Accordingly, a durable, simple non-gauze system for automatically clearing blood/fluid from a surgical site is described.

The invention relates to a suction device for intraoral use, comprising a suction line and a tongue protection, said suction line being bent substantially U-shaped, which are configured by a molded part, in particular integrally with one another. The suction tube comprises a connection which points mesially for a suction hose. In the course of the suction tube the connection is adjoined by an upper U-leg, a mesial U-central portion and a lower U-leg, said legs extending distally from the U-central portion. The lower U-leg comprises suction openings and is surrounded by a suction sponge which covers the suction openings. The suction tube terminates at the distal end of the lower U-leg in an end suction opening which is covered by the suction sponge.

A suction handpiece for a dental treatment unit has a negative pressure connection which can be connected with a negative pressure source of the treatment unit. A saliva connection of the suction unit can be connected with a saliva suction cannula and an atomized spray connection that can be connected with an atomized spray suction cannula. A branched flow path connects the negative pressure connection with both the saliva connection and the atomized spray connection and includes a branching section on which a negative pressure channel ending on the negative pressure connection divides into a saliva channel ending on the saliva connection and an atomized spray channel ending on the atomized spray connection. The atomized spray channel at its narrowest point has a first cross sectional area which is at least twice as large as a second cross sectional area at the narrowest point of the saliva channel.

Dental instrument assemblies (e.g., mouth pieces, bite blocks, vacuum dental mirrors, illuminated dental mirrors, illuminated dental wedges, trans-illumination dental instrument, illuminated dental bite blocks, etc.) are provided. The dental instrument assemblies may be adapted to be periodically sterilized. The dental instrument assemblies may include a magnetically energetic fiber optic coupler. The magnetically energetic fiber optic coupler may be configured to allow dental instrument adapter to rotate with respect to an associated fiber optic cable that is removably connected to the magnetically energetic fiber optic coupler. The dental instrument assemblies may include a fiber optic material that is encapsulated.

A dental mouthpiece is provided that may be attached to a high-suction dental adapter for the purpose of assisting the dental staff during dental procedures through chair-side, hands-free suction, and isolation. Such a mouthpiece may comprise a main body portion, a cheek retractor portion, and a suction connector portion. In an embodiment, the main body portion, cheek retractor portion, and suction connector portion may be molded in one piece, preferably by injection molding. The main body portion has an anterior wall inside the curve and a posterior wall outside the curve, and an at least one connector connecting the anterior wall and the posterior wall. The main body portion has an anterior intervening wall and the posterior intervening wall in between the anterior and posterior walls. The anterior intervening wall and the posterior intervening walls have alternating crests and troughs.
