What are the dental prostheses?
Dental prostheses are sanitary products or dentures made of different materials and with multiple characteristics, which serve to rehabilitate and replace missing teeth.
What types of dental prostheses are there?
The prosthesis can replace all the teeth of an arch (complete prosthesis) or only part of them (partial prosthesis).
These removable prostheses consist of artificial teeth attached to an acrylic and / or metallic base, which rests on the gum and is attached to remaining teeth (if they exist) by means of retainers (colloquially called "hooks") or to implants (implant-retained overdentures) by means of fastening mechanisms anchored to them and specific clamps, located inside the prosthesis.
Complete prostheses or full dentures are made of acrylic (in the exceptional case of an allergy they can be made of titanium) and are attached to the gingiva by a "suction cup" effect, very limited in the case of the lower ones; In fact, it is so limited that it is considered inevitable that the lower full dentures will have some kind of movement with the movements of the lips and the tongue, that is, when speaking and chewing.
Treatment with a removable partial denture is the clinical procedure aimed at restoring missing teeth using medical devices that can be removed from the mouth without the need for the dentist, at the patient's own will.
Partial appliances, so called to replace a part of the teeth and not the whole, can be:
- Metálicos (habitualmente de cromo-cobalto, aunque en casos de alergia se pueden confeccionar en oro o titanio), coloquialmente conocidas como esqueléticos.
Fixed prosthesis treatment is a clinical procedure aimed at restoring missing teeth by means of fixed appliances, permanently attached to some natural teeth remaining in the mouth or to osseointegrated implants. Unlike the removable prosthesis, this appliance cannot be removed by the patient by their own means.
That is, retained by implants, in which the prosthetic structure can be screwed or cemented on some abutments that are, in turn, screwed to the implants.
It is a tooth-supported fixed prosthesis, in which it is necessary to grind (carve) the teeth that serve as support, removing a thin layer of thickness.
