In the eye's case, however, the film screen is your retina. Your retina is in the very back of the eye. It holds millions of cells that are sensitive to light.

Dentures, also known as false teeth, are prosthetic devices constructed to replace missing teeth; they are supported by the surrounding soft and hard tissues of the oral cavity.
Dentures are false teeth people use after losing one or more natural teeth. There are several types of dentures like complete, partial, upper and crowns. Dentures that are made to replace teeth in the upper jaw are called upper dentures. Your dentist should be able to advise you, which type of denture is best suited to your needs. Types of upper dentures are complete, partial, immediate, over dentures and implant-retained. Complete or Conventional Upper Dentures Complete upper dentures are meant to replace all of the teeth in your upper jaw, and they are supported directly by the upper jaw bone.
