There is disclosed a dental device configured to be coupled to a vacuum. In at least one embodiment the device comprises at least one channel coupled to the vacuum and in fluid communication with the vacuum. In addition, there can be at least one hood coupled to the channel, and covering the channel wherein the hood is in fluid communication with said at least one channel. In addition, there can be at least one clip coupled to the hood. Furthermore, said at least one clip extending substantially perpendicularly to said at least one hood and substantially parallel to said at least one channel, wherein the vacuum is configured to create a negative pressure inside of said at least one hood, and wherein said at least one clip is configured to couple to a user's mouth, wherein said hood is positioned adjacent to a user's mouth.

A headgear can be worn on a user's head to adjustably fix a mouthpiece inserted in an oral cavity. The headgear includes: a front pad brought into contact with and pressed against a front pressure point of an outer surface of the buccinator between the zygomatic bone and the mandible in the face region; one or more rear pads brought into contact with and pressed against one or more rear pressure points so that a resultant force becomes a reaction force paired with a pressing force of the front pad, in a region from the top to the back of the head; a frame fixing the front pad and the rear pads; a front horizontal bar fixed to the frame at a position in front of the lip region of the head; and an adjustment part installed on the front horizontal bar to mount the mouthpiece.

An orthodontic appliance for installation on an archwire is described. The orthodontic appliance has two archwire sliding parts, for sliding along an archwire, a telescoping assembly linking the two archwire sliding parts to one another, an external force conveyer and a spring secured to one of the archwire sliding parts. The telescoping assembly is offset from the archwire on which it is to be installed. A method for exerting pressure on a target orthodontic bracket that is connected to adjacent orthodontic brackets by an archwire is also described. The method uses the described orthodontic appliance.
