Complete dentures or full dentures are plastic plates with teeth custom-made to fit each individual. It is made from pink acrylic simulating gum tissue and plastic or porcelain teeth, custom set for each patient. Complete dentures are made for edentulous patients (with no teeth). Apart from replacing teeth, they also improve appearance by mimicking gums with the pink acrylic and the overall facial height and width.
Sometimes, some of the teeth can be saved to preserve the jawbone and provide stability and support for the denture. Such kind of a denture is called an Over-denture. An over-denture is also a complete removable acrylic denture which apart from being supported by the soft tissues is also held in the mouth with the help of the remaining teeth, which are prepared in a manner to provide such a function. This extra support makes the over-denture a better form of a complete denture and is preferably done whenever possible.
