Medical handpiece for dispensing filling material

A medical handpiece for dispensing filling material on one or more of a human tissue, an animal tissue, a prosthesis for human tissue, and a prosthesis for animal tissue, the handpiece comprising:

• a connection device for a filling material container, a vibration unit for the generation and transmission of vibrations on the filling material and a conveying device for conveying the filling material from the container, wherein the vibration unit is operable in an automated operating mode for pulsed power output on the filling material, wherein for providing the pulsed power output, the vibration unit is configured to be one of:
• i) switched alternatingly between a first condition in which the vibration unit applies vibrations to the filling material, and a second condition in which the vibration unit does not apply any vibrations to the filling material, or
• ii) operated alternatingly with two different frequencies.

A method for dispensing filling material on one or more of a human tissue, an animal tissue, a prosthesis for human tissue, and a prosthesis for animal tissue with a handpiece comprising a connection device for coupling the handpiece to a filling material container, a vibration unit comprising a sonotrode for generating and transmitting vibrations to the filling material and a conveying device for conveying the filling material from the container, the method comprising:

• moving the sonotrode with the conveying device towards the connection device for the filling material container, such that the sonotrode pushes filling material from the filling material container.

A method for use in one or both of dispensing filling material on one or more of a human tissue, an animal tissue, a prosthesis for human tissue, and a prosthesis for animal tissue, and modelling of filling material dispensed on a preparation site with a handpiece comprising a connection device for a filling material container, a vibration unit for the generation and transmission of vibrations on the filling material and a conveying device for conveying the filling material from the container, the method comprising:

• operating the vibration unit in an automated operating mode in which a pulsed power output is transmitted on the filling material, wherein operating the vibration unit comprises one of:
• i) alternatingly switching the vibration unit between a first condition in which the vibration unit applies vibrations to the filling material, and a second condition in which the vibration unit does not apply any vibrations to the filling material, or
• ii) alternatingly operating the vibration unit with two different frequencies.
