A device for shielding teeth to be treated in order to prevent an inflow of liquid, such as saliva or bloody the device comprising a partial dental dam () comprising a tensioning cloth () made of an elastic material designed to be introduced into at least one intermediate tooth space () when in an elongated state, and two actuation elements () arranged on opposing ends of the tensioning cloth () for use in pulling the tensioning cloth () into an elongated state, and use of the device for shielding teeth to be treated.

Device for sheilding teeth to be treated

A method for producing a multicomponent compound involves pressing components out of cartridges by means of pistons. The method has particular applicability in connection with dental applications. The method prevents pressing the components initially under high pressures. At the beginning of the pressing-out process, a pressure lower than the characteristic pressing-out pressure of the components from the cartridges is employed. Feed speeds are adjusted to constant value as a function of the pressing-out behavior of the components which are compared with stored or calculated values for a known material.

Method and device for producing a multicomponent compound

A device for producing a multi-component compound, in particular for dental purposes, by mixing its components after they have been pressed out of cartridges which open into a dynamic mixer and are arranged exchangeably in the device, with a first motor for advancing all of the pistons assigned to the cartridges, and with a second motor for rotary driving of mixing elements in the mixer via a shaft, which is held in engagement with the mixer by spring pretensioning and can be pulled back from the mixer counter to the spring pretensioning, is characterized in that the shaft is provided with a radially extending projection which, by the spring pretensioning, is pressed onto a ramp-like upwardly sloping cam surface, which is provided on its foot with an abutment surface, of a toothed wheel, which is provided with saw-like teeth and is coaxial to the shaft, which toothed wheel, in a first angle direction in which the cam surface slopes upwards, is prevented from rotating by a catch and, in the second angle position opposite thereto, is rotatable, the mixer drive shaft being pulled back during rotation in the first direction of rotation.

The subject of the invention is a dynamic mixer for viscous compositions, in particular for components for dental impression compounds. The mixer consists of a mixer tube, a rotor located in the latter, and an end wall with inlet openings through which the components to be mixed pass into the mixer. In doing so, they first alternately fill chambers arranged on the rotor. The composition then flows out of the chambers through admission openings into the mixing channel, where it can be stirred by mixer blades.
