The preventive prosthesis: Place of the over dentureAbstract:
The concept of the supra-radicular complete removable prosthesis allows the dentist to assume an important role in the preservation of natural teeth and supporting structures. In many cases, the teeth that would be extracted can be conserved and this contributes to improving the retention and stability of the definitive prosthesis in a significant way. Bone is a dynamic tissue. The extraction of teeth causes the initiation of bone resorption. When the tension force is received by the bone of the supporting teeth, supplementary bone formation takes place. These forces are produced when they are transmitted to the alveolar bone via the periodontal ligament. Therefore the supra-radicular complete prosthesis may not be the elixir, but it is a positive means of retarding the process of bone resorption and maintaining bone volume as well as restoring esthetics. The aim of our work is to clarify the keys to success in supra-radicular restorations which require a rigorous pre-analysis to reconcile balance optimization with the advantages and inconveniences which will also be discussed.
