DEVICE: Preat (00842092169223)

A round shaft of substantial dimensions designed to be used in the dental laboratory to hold (locked into place) a rotating device, e.g., a grinding or polishing wheel, abrasive disk, circular saw, or a disk, stone or cup used for grinding or polishing; connectors and rotating endpieces may be included with the device. The mandrel will be placed into a laboratory dental handpiece or lathe that will rotate at high speed. This is a reusable device.

A rotary cutting device made from high-grade carbon steel with the working end typically formed with cutting planes, e.g., spiralled flutes, and which is designed to fit into a dental handpiece that provides the rotation allowing the user to cut hard structures in the mouth, such as teeth or bone. It can also be used to cut hard metals, plastics, porcelains and similar materials intended for use in the fabrication of dental devices. It is available in various shapes (e.g., cylinder, disk, sphere, oval). This is a single-use device.

A manual dental laboratory instrument intended to be used in a dental laboratory during fabrication or revision of a final dental prosthesis (e.g., denture, crown, bridge) to integrate and/or adjust the fitting between male and female precision attachments. It is in the form of a handle with a distal end designed to perform a dedicated function (e.g., facilitate the parallel placement of a male attachment, remove/exchange/adjust an attachment, insert a retention insert, tighten a screwable element of an attachment); some types may be heated to enable melting, or attached to a motorized handpiece (e.g., drill). This is a reusable device.
