Complete Denture
Complete denture prosthodontics: involves an artificial replacement of the lost natural dentition and associated structures of the maxilla and mandible for patient who has lost all their remaining natural teeth. Complete denture A removable dental prosthesis that replaces the entire dentition and associated structures of the maxilla or mandible.

Delivery to the patients
Function of complete denture: 1 - Mastication: chew food for swallowing and digestion. 2 - Speech (phonetics): the teeth either natural or artificial assist the tongue and lips to form some of the sounds of speech. 3 - Appearance (aesthetic): is influence by the shape of jaws together with the position and occlusal relation ship of the teeth. 4 - Health of the alveolar bone and the tempromandibular joints (T. M. J).
