Function of complete denture:Function of complete denture:Function of complete denture: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 tempro- mandibular joints

(T.M.J).
