Abstract: The invention relates to a reusable syringe with a syringe body for receiving an ampoule. At the front end of the syringe body there is an opening which defines an axis along which a needle can be inserted. A plurality of holding segments are arranged around this axis and engage behind a needle carrier in the longitudinal direction. According to the invention, a holding segment designed as a thread part is movable in the radial direction. The invention further relates to a system composed of a reusable syringe, a needle carrier, and a container for used needles. Moreover, the invention includes an associated method for connecting and releasing a needle of a reusable syringe. The movable holding segment facilitates the release of the threaded connection of the needle carrier from the syringe body and makes the reusable syringe safer to use.

Abstract: The invention relates to an applicator instrument for applying dental compounds. The applicator instrument comprises an instrument head with a support structure and with a plurality of projections formed on the support structure. The projections are elastic and, in relation to a height extent, have less stiffness than the support structure. Between them, the projections enclose a receiving space for the dental compound. According to the invention, the projections have a planar configuration and, in relation to a width extent, are arranged substantially parallel to one another. The greatest diameter of the instrument head is between 2 mm and 3 mm. With the applicator instrument according to the invention, it is easier to apply the dental compound in dosed amounts and to spread the dental compound across the surface that is to be treated.

Abstract: An application device for dental compositions. At the rear end, the application device is provided with a connection for a discharge container. A channel extends from the connection to a channel opening arranged at the front end. Flat protrusions are formed at the front end, which enclose therebetween a receiving space for the dental composition. Using the receiving space, the excess dental composition can be taken up again and removed.

Abstract: The hermetically closed disposable container contains a substance or a substance mixture and is equipped with a break-off location for opening the container. The container consists of plastic and is constructed of a vessel and of a closure, wherein the closure after the filling of the substance or substance mixture into the vessel is connected to the vessel with a material fit. The break-off location is provided on the outer circumference of the container so that this may be easily broken open.
