Dentures are removable appliances which are used to replace missing teeth and tissues. These are made of acrylic and metal. They are the artificial teeth which enable normal functioning of human mouth. Dentures are of two types – Complete, replacing all the teeth & Partial, replacing certain missing teeth.

For patients who cannot or do not wish to undergo surgical intervention, removable dentures are an alternative for replacing missing teeth. Function wise these  are inferior to fixed teeth because they derive support from the oral mucosa only.
However, wearing the dentures sincerely for some amount of time makes the patient adapt and accomodate the removable prosthesis pretty well.

These are made up of usually material called Poly Methyl Methacrylalate (PMMA), but can often be reinforced by a metal frame work for increasing strength. Now a days, newer materials like flexible denture material have become the best choices for the patients because they do not break on falling down or impinge on to the mucosa, leading to better patient compliance.
