Invisible denture, also called invisible teeth, is an old technology from the early years that has been gradually eliminated from dentistry because of certain hazards, and is now a treatment used mainly by small clinics or dentistry departments for over restoration. It is made of elastic plastic, with teeth and gums on it, and it is stuck to the gum surface through the gum part of the abutment, which is very beautiful after it is made, and other people cannot easily find that it is a denture, unlike the bracket denture which has hooks, this denture is without hooks, and it completely relies on elastic retention, which is beautiful but presses too much on the alveolar bone, and it is very easy to lead to alveolar bone resorption.
