  • SYSTEM AND METHOD FOR CLEANING SPACE BETWEEN FIXED DENTURES AND GUM LINES
    Publication number: 20250255702
    Abstract: A system for cleaning space between dentures and gum lines that has a substantially planar, flexible mouthpiece with a longitudinal axis. A proximal end of the mouthpiece substantially forms a crescent. A distal end of the mouthpiece stems perpendicularly from the proximal end of the mouthpiece. The mouthpiece has coplanar ingress half and egress half separable by a central planar axis. The ingress half has a plurality of ingress proximal ports fluidly connected to at least one ingress distal port. The egress half has a plurality of egress proximal ports fluidly connected to at least one egress distal port. Pressure differentials in the ingress fluid channel propel fluid out of the ingress proximal ports. Pressure differentials in the egress fluid channel draw at least fluid into the egress proximal ports. Pressure differentials in the ingress and egress fluid channels are designed to be generated simultaneously by a pump and vacuum.
