Publication number: 20220022998Abstract: A dispensing device for dental retraction material. The dispensing device has a cannula that forms a free front end. The free front end is formed by a first cannula portion and a second cannula portion that is arranged directly adjacent the first cannula portion. The first cannula portion has a first elongated section and a first rounded section. The second cannula portion has a second elongated section and a second rounded section. A first outer diameter (D1) of the cannula is defined on the first rounded section at the free front end, and a second outer diameter (D2) of the cannula is defined on the second rounded section at the transition between the second rounded section and the first cannula portion. The second outer diameter is greater than the first outer diameter. The first cannula portion comprises a predetermined separation structure directly adjacent the second cannula portion. The first cannula portion can be broken or cut off to provide the dispensing device with a new free front end.Type: ApplicationFiled: November 22, 2019Publication date: January 27, 2022Inventor: Helmut Pauser

Publication number: 20210113301Abstract: A dispensing gun for dispensing a dental material. The dispensing gun has a body with a receptacle for receiving a cartridge therein, a plunger that is displaceable relative to the receptacle, and a lever that is suspended pivotally relative to the body. The plunger has a linear toothing and the lever has an annular gear segment. The linear toothing and the annular gear segment are permanently engaged with each other so that any pivot of the lever in a first direction causes the plunger to displace forward and any pivot of the lever in an opposite second direction causes the plunger to displace backward.Type: ApplicationFiled: April 10, 2019Publication date: April 22, 2021Inventors: Helmut Pauser, Marc Peuker
