A method for excavating tooth material, having the steps of placing (S) a structure-borne sound sensor on a tooth; excavating (S) the tooth material by means of a fluid jet; detecting (S) structure-borne sound signals during excavation by the structure-borne sound sensor; and regulating or controlling (S) a fluid jet generating device based on the structure-borne sound signals.

Method for excavating dental material

The present invention relates to a device and a method for the application of composites in tooth cavities. The device consists of a spray gun with integrated lighting for light-polymerizable composites, a measuring unit and a control unit. The composites are applied under controlled, precisely dosed exposure to polymerization light. According to the invention, the composite initially runs onto the walls of the cavity or onto previously introduced filling material and then, as a result of the light exposure, is transformed into the gel state. Thus, a large part of the polymerization shrinkage of the composite occurs while the composite is still plastically deformable so that any formation of gaps is compensated by the composite continuing to flow. It is only at this point in time that a sufficiently high dosage of light is applied for complete curing to occur.
