Abstract

A hollow-cylindrical device () having first and second openings () for continuous production of a dental composite block. A curable composite material () and a temperature control unit () are provided. The composite material () is introduced into the device () through the first opening. The composite material () is cured by energy from the temperature control unit (). An energy input occurs across a defined length of the substantially hollow-cylindrical device () and/or for a defined period of time. The composite material () is subsequently guided through the first opening () of the device (). The composite material () is discharged from the second opening (). In a first region along a portion of the length of the device, the device is either provided with an insulation or the flow-through device has a heat conductivity of 0.05 to 12 W/(m×K).
