An oral irrigator handle has a handle housing with a swivel assembly for connection to a hose further connected to a fluid source. A tip for directing a focused stream of fluid is releasably connected to a first end of the handle. The swivel assembly is received within the housing and fluidly coupled to tip. The hose is connected to the swivel assembly and fluidly coupled to the tip via the swivel assembly. The swivel assembly prevents translation of rotational movement of the handle or the hose to the other.

A valve assembly for a dental suction system. The valve assembly includes a valve body having an inlet, an outlet and a fluid flow path extending between the inlet and the outlet. The valve assembly also includes a valve plug positioned at least partially within the valve body and including a through-passage. The valve plug is rotatable relative to the valve body to selectively alter a flow of fluid along the fluid flow path. The fluid flow path exhibits a varied cross-sectional area along a length of the fluid flow path.

An orthodontic system and method for aligning at least one tooth of an upper jaw or a lower jaw of a patient. In the system and method at least one orthodontic appliance can be provided which may include at least one force exerting member for applying a force to move the at least one tooth, a tooth movement sensor for obtaining tooth movement data, and a tooth movement monitor for calculating at least one of the distance the at least one tooth has moved and a current position of the at least one tooth from the tooth movement data. An electronic control console may be operatively connected to the force exerting member and in data communication with the tooth movement monitor, for controlling the operation of the force exerting member using the at least one of the distance the at least one tooth has moved and the current position of the at least one tooth.

Embodiments of the invention include a handpiece system including a detachable cable that can receive at least power, and a detachable cable connector, where the detachable cable connector and detachable cable are reversibly attachable to each other. In some embodiments, the system includes an interchangeable laser module, where the laser module and detachable cable connector are reversibly attachable to each other. Further, the interchangeable laser module is configured and arranged to receive at least the power via the cable connector when coupled to the cable connector, and to be removed from the detachable cable connector and replaced with another laser module. In some embodiments, the system further includes an interchangeable handpiece which is reversibly attachable to the interchangeable laser module. Further, the interchangeable handpiece is configured and arranged to be removed from the interchangeable laser module and replaced with another interchangeable handpiece.

A shelf for a dental delivery system comprises a shelf member and device mounting locations on the shelf member. The shelf member is shaped to fit within a dental delivery system housing. The shelf member is movable between at least a closed position and an open position. The device mounting locations define locations devices can be coupled. According to another implementation, a dental delivery system comprising a housing defining an interior, at least one connection extending from the housing to a dental handpiece holding area, a removable cover and a shelf member movable between at least open and closed positions is described.

A conduit guide includes a main body having a first portion and a second portion, the first portion being configured for attachment to a dental delivery unit, the main body defining a channel along at least a portion of its length configured to receive a utility conduit. A positioning assembly is disposed within the main body, and includes a first attachment member, a second attachment member, a biasing member, and an adjustment member. The biasing member is coupled to the first attachment member and to the second attachment member, and extends between the first attachment member and the second attachment member. The adjustment member is coupled to the biasing member and configured to axially move the biasing member to adjust a position of the conduit guide. The conduit guide is configured such that at least the adjustment member of the positioning assembly can be selectively accessed and enclosed within the main body.

A dental delivery system can comprise a first fluid conduit for supplying fluid via the delivery system to a handpiece connected to a distal end of the conduit, a plurality of flow control adjusters positioned on the delivery system at a location remote from the at least one fluid conduit, and an indicator circuit comprising a plurality of sensors and a plurality of indicators corresponding to the plurality of flow control adjusters. A first flow control adjuster of the plurality of flow control adjusters can be operable to change a fluid flow rate in the first fluid conduit. A first sensor of the plurality of sensors can be operable to trigger a first indicator of the plurality of indicators in response to predetermined motion of the first fluid conduit to indicate that the first flow control adjuster is associated with the first fluid conduit.

A disposable dental valve device is disclosed having a valve body having a tip receiving end, a hose receiving end, a lumen formed between the tip receiving end and the hose receiving end, a partial opening formed in the valve body, and a rotatable valve sealing body adapted to being inserted into the partial opening, the rotatable valve sealing body having a bore for alignment with the lumen formed between the tip receiving end and the hose receiving end, the bore having a tip receiving opening and a hose receiving opening, the rotatable valve sealing body having a check valve positioned on the tip receiving opening, and the rotatable valve sealing body having a top and a handle portion connected to the top.

A tailpiece for a dental valve device is disclosed which has a body having a valve receiving end, a hose receiving end, and a hose retaining section having a hose insertion section, an inclined section, a first flat section, a first tapered ring section having a central section, a second flat section, a second tapered ring section having a central section, and a third flat section.

A dental treatment system can include a console, a tooth coupler, and an interface member that provides at least one of fluidic, electrical, mechanical, and data communication between the tooth coupler and the console. The tooth coupler (which may comprise a handpiece or a treatment cap) can act as a working end of the system to administer a suitable treatment procedure, such as a cleaning procedure, an obturation procedure, a restoration procedure, etc. The tooth coupler can removably engage the interface member such that the clinician can easily engage and disengage the tooth coupler and interface member.
