Prosthesis removable
Acrylic and skeletal

Removable dentures can be partial or total. The partial removable prosthesis can be entirely acrylic or have a metal part called skeleton and are intended to replace one or more teeth. The latter are known as skeletal prostheses. There are also flexible dentures.

The partial removable acrylic dentures are the most economical and should be only temporary. However it is the most used for socio-economic reasons. This type of prosthesis is held in the mouth by retentions present in remaining teeth.

The removable surface, better known as dentures are usually acrylic and intended to replace all teeth. They are only supported by the soft tissue and underlying bone structure. Remains in the mouth by the joint action of small retention of the anatomy that remains on the alveolar bone, tongue, facial muscles, and in the case of upper dentures, the vacuum effect between the inner surface of the prosthesis and the palate (roof of mouth). The retention of these prostheses is very problematic when there is an almost total resorption of the alveolar bone. In this situation the only solution is resort to implants.

Developments in removable prosthodontics

The flexible dental prosthesis is a prosthesis made with specific resins. Due to its specifications the prosthesis is completely flexible, maintaining the rigidity required for replacement of missing tooth function. This new type of prosthesis is very popular among people who do not fit the rigid convencional acrylic prosthesis.

Flexible prosthesis presents advantages, such as:

• High comfort in use
• less pronounced prosthesis wear
• Virtually unbreakable - less likely to fracture prosthesis
• Lower incidence of injury or pain from the use of the prosthesis
• Minor gingival irritation
• Higher masticatory efficiency compared with conventional prostheses.
