Dental Cleaning Device

원문 (중국어)

A mouthpiece including a body having a recess delimited by a flexible recess wall, the recess configured for encompassing a plurality of dental positions. The body is provided with a pressure chamber for containing a fluid under pressure. The recess wall is configured to deform by reciprocatingly increasing and decreasing a pressure in the pressure chamber between a decreased pressure condition and an increased pressure condition. The recess wall has a local deformability such that, when reciprocatingly increasing and decreasing the pressure in the pressure chamber, a shape of the recess wall locally changes. In the increased pressure condition, the shape of the recess wall is locally adjusted to the local shape of the dental positions encompassed by the recess wall. In the decreased pressure condition, the shape of the recess wall is locally less adjusted to the local shape of the dental positions encompassed by the recess wall.
