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.

The present disclosure provides a treatment assistance apparatus, comprising: a base; a first joint of which one side is coupled to the base to relatively move; a first arm of which one end is rotatably coupled to the other side of the first joint; a second joint of which one side is rotatably coupled to the other end of the first arm; an adapter arm of which one end is coupled to a first adapter to relatively move, and the first adapter is rotatably coupled to the other side of the second joint; a first driving part disposed in the first joint and configured to rotate the first arm; a second driving part disposed in the second joint and configured to rotate the adapter arm; a pressure part configured to stop a relative motion of the first adapter; and a controller configured to control the first driving part, the second driving part and the pressure part.

A shelf assembly comprises a shelf, an arm having a distal end and a proximal end, a first pivot connection between the shelf and the distal end of the arm, and a second pivot connection between the proximal end of the arm and a base. The base comprises a drawer movable in translation between at least a storage position and an operating position. A cabinet for a swing-out shelf is also described.

A medical treatment apparatus includes a power and control (PAC) device. The PAC device provides electrical power through a cable to a laser handpiece assembly to electrically power a laser source within the handpiece assembly. The PAC device controls operation of the handpiece assembly and detects an identification of the handpiece assembly. The PAC device also monitors data relating to operation of the handpiece assembly. The PAC device uploads, through a communication network to a user assistance center remote from the PAC device, the handpiece assembly identification and the monitored data.

A medical chair protective barrier and gas distribution system provides a frame that forms a sealed environment for a medical gas delivered to head of a dental chair. The frame fastens to the medical chair, or rolls to head of medical chair. A laminar flow subassembly secures to frame. The laminar flow subassembly includes a vacuum pump, tubing, positive and negative pressure ports, and a vent for delivering medical gas to the head of medical chair. The frame carries a hood that covers the head of medical chair. The hood retains medical gases in a sealed environment, while protecting dentist from contact with medical gases. The hood includes a window and a pair of arm passages that regulates access to inside of hood. Medical armamentarium hangs on frame for access. System has inlet and outlet vacuum ports that utilize HEPA filters and hidden UV lights for disinfecting under the hood.
