A denture is a removable replacement for missing teeth and surrounding tissues.
Two types of dentures are available – complete and partial dentures. Complete dentures are used when all the teeth are missing, while partial dentures are used when some natural teeth remain.
Complete dentures are made of a plastic base (acrylic resin) that is coloured to replicate gum tissue and supports a full set of teeth (plastic or porcelain) . The traditional full denture is held in the mouth by forming a seal with the gums which creates a retention pressure. They can also be attaching to dental implants that are surgically placed in the jaw bone
Partial dentures can either be made with a plastic base or a metal framework that supports the number of teeth that need to be replaced. It is held in the mouth by using clasps and rests that are carefully adapted around the natural teeth. The partial denture that uses a metal framework is the traditional design, due to the rigidity and strength of the metal. Plastic partial dentures have normally been used as emergency or temporary replacements of missing teeth, allowing the gums and bone to heal before a definitive restorative solution is obtained. Recently, however, various materials such as Valplast have been developed to provide durable, flexible alternatives in certain situations.
