Nozzle system for a powder blasting device including a first nozzle element for transporting a powder-gas mixture stream along a transporting direction and a second nozzle element, where the second nozzle element surrounds the first nozzle element such that at least one channel is formed between the first nozzle element and the second nozzle element, where the channel is provided for transporting a liquid stream, where the first nozzle element and the second nozzle element are arranged such that in operation the powder-gas-mixture stream ejected by the first nozzle element is encased by the liquid stream ejected by the channel for forming an output stream of the nozzle system, where the first nozzle element has an acceleration part having a first cross section and a spreading part having a second cross section, where the spreading part is arranged downstream of the acceleration part.

A handpiece of a medical or dental device allows a user to hold, support, and/or operate the handpiece by placing a portion of the user's hand, such as one or more fingers (e.g., the forefinger) through an ergonomic aperture in the handpiece.

A powder for cleaning an internal body part and/or an implant, in particular by means of a powder jet device, wherein the powder is sterile as a result of a sterilizing process.

A method for removing dental material is disclosed. The method may include suspending, by a hydrated polymeric material, a quantity of abrasive media. The hydrated polymeric material and suspended abrasive media may then be pressurized. Accordingly, an abrasive stream may be formed by expelling, under pressure, the hydrated polymeric material and suspended abrasive media from a nozzle. The abrasive stream may be precisely applied to a tooth to abrade the enamel or dentin thereof as a drilling instrumentality.

The present invention relates to a portable and 360 degrees operational particle blast system comprising a blast device (35) for blasting particles, comprising a blasting wheel (6), the blasting wheel comprising a rotor (6A), having blades (14) for accelerating the particles to be blasted through an exit mouth (33) of the blast device, a stator (6B) with a control cage (17), the blast device further comprising a control system (10). The latter comprises a controller for controlling the speed and the flow rate of the particles to be blasted. The system further comprises a removable, pre-filled, closed recipient (7), suitable to be operationally connected to the blast device, said recipient containing the particles to be blasted, and further comprising i.a. an actuator, acting upon a movable piston (22), causing the particles to flow against the valve to the blasting wheel and means for communicating upon connection of the recipient to the blast device, to the controller of the blast device, the operational parameters, whereby the speed and the flow rate of the blasted particles are determined by the controller solely as a function of the operational parameters received from the recipient.

An instrument for performing periodontal surgery comprises a longitudinally extending handle, a blade section comprising at least one cutting edge, a connector comprising a first end coupled to the handle and a second end coupled to the blade section. The connector spaces the blade section laterally from the handle, relative to a longitudinal extent of the handle, and the cutting edge(s) define a cutting plane that is substantially parallel to the longitudinal extent of the handle. The instruments provide a three-dimensional structure that facilitates periodontal surgery.
