An apparatus and method for purging a dental air/water syringe comprises at least one of a button hold-down device for holding down at least one button of the syringe for discharging fluid therefrom and a collection container for collecting the discharged fluid. The button hold-down device includes axially spaced contact surfaces for contacting a syringe body and the button so that the device is supported mounted on the syringe body in a working position. The collection container features an interior perforated false bottom wall under which is formed a collection space where the discharged fluid collects, and a drain is communicated with the collection space for removing the collected fluid therefrom. The drain can be connected to a saliva ejector for removal of the fluid by suction.

The invention relates to a dental coupling unit (1), which can be detachably coupled to an instrument attachment (2) for dental treatment and/or examination at the front end (11) of the coupling unit and also can be connected to a supply unit (3) for providing supply media for the instrument attachment (2), wherein a media supply line (4) extends through the coupling unit (1) toward the instrument attachment (2) and wherein additionally a media return line (5) extends through the coupling unit (1), which media return line is connected to an end region of the media supply line (4) extending through the coupling unit (1), which end region faces the instrument attachment (2). The coupling unit (1) has a valve assembly (6), which conducts the liquid from the coupling unit (1) to the instrument attachment (2) when the instrument attachment (2) is attached and conducts the liquid to the media return line (5) and blocks the escape of the liquid at the front end (11) of the coupling unit (1) when the instrument attachment is not attached.

A method for preparing and/or caring for a medical or dental instrument is defined in that the instrument jointly with a connection adapter is first connected to a first preparation and/or care device and subsequently to a second preparation and/or care device. Furthermore, a coupling device is described which is configured to connect a preparation and/or care device for a medical or dental instrument to a connection adapter. A plug-in coupling arrangement and a system are also disclosed.

The invention relates to a treatment system (1) for cleaning a component contaminated by biofilm, more particularly for cleaning bacterially contaminated surfaces of bone implants or dental implants (30), the treatment system comprising at least two conductor elements (2, 4) connected to an electrical supply unit (10) to form an electrical circuit. One of the conductor elements can be brought into electrical contact with the component in need of treatment. The object of the invention is to provide a treatment system of this type which allows a particularly acceptable and flexible treatment. To this end, according to the invention at least one of the conductor elements (2, 4) is designed as a diamond electrode (26).

A cleaning device provides for quick, thorough and pleasant multi-parallel cleaning of teeth and gums through use of a pressurized cleaning liquid, applied to teeth and gums by a cleaning headpiece with a plurality of cleaning nozzles and with optimized and practical geometry as well as readily applicable control of the clean by the user. Sensations of suffocating or drowning, which can be serious detriments and hindrances of prior art devices, are effectively overcome. In a preferred embodiment, teeth are cleaned in two steps, where each step cleans the teeth and gums in just over one side of the user's jaws. The device can simply be extracted, flipped by 180 degrees and reinserted into the mouth between the two steps.

Medical or dental cleaning and/or care device for cleaning and/or care of at least one instrument, comprising: a housing, a plurality of chambers, each of the plurality of chambers configured to accommodate at least one instrument, wherein each chamber has at least one dispensing element for dispensing at least one cleaning agent and/or care agent into the respective chamber and/or to the instrument accommodated in the respective chamber, an opening in the housing, through which the plurality of chambers can be loaded with instruments, and a cover for closing the opening and the plurality of chambers, wherein only a part of the opening can be closed by the cover so that when at least one of the plurality of chambers is completely closed, at least another one of the plurality of chambers is not completely closed.

A system for ultrasonic cleaning of dental appliances provides nested containers adapted to communicate ultrasonic energy therethrough to provide cleaning of a dental appliance contained within the innermost container using a standard ultrasound machine without cross-contamination with liquid from the main ultrasound bath.

A novel dental cassette featuring a pop-in securing gripper-rails system to clamp odd-shaped dental instruments, while providing adjustable canting, gripping, and drainage capacity through its materials, design and engineering. The silicon gripping posts and feet, and the shovel-and-groove clamps, and the plurality of hex [preferred] holes, provide superior anchorage for dental instruments through autoclave and sterilization processes.

A lubrication information management device includes: a lubrication detector provided to a lubrication unit; an instrument wireless tag provided to an instrument; and a read-write unit which is either an antenna or a reader-writer. Moreover, the read-write unit communicates lubrication information to the instrument wireless tag when the lubrication detector detects any of lubrication of the instrument and an operation for lubrication. This makes it possible to reliably manage the lubrication of a dental instrument.

A method for preparing and/or caring for a medical or dental instrument is defined in that the instrument jointly with a connection adapter is first connected to a first preparation and/or care device and subsequently to a second preparation and/or care device. Furthermore, a coupling device is described which is configured to connect a preparation and/or care device for a medical or dental instrument to a connection adapter. A plug-in coupling arrangement and a system are also disclosed.
