Is a removable prothesis with a crome cobalt structure. It is removed from the mouth when brushing the natural teeth. It is held in place with hooks in the remaining teeth. It is a more than 100 years old treatment, a classic treatment that works very good, if well done. It is quick, no sanding required and is less expensive than the rest. It lasts years and the patient gets accustomed to it, even forgetting that it is there.
