DEVICE: Preat (00842092108635)

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.

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 dental fixation device designed to give a tooth-borne/tissue-borne prosthesis sufficient mechanical play to withstand the variations in the seating of the prosthesis due to deformation of the underlying tissues, without placing excessive stress on the abutments.
