The term CAD/CAM, which comes from machine-tool technology and stands for ¿Computer-Aided-Design / Computer-Aided-Manufacturing¿, designates the three-dimensional planning of a workpiece on the screen of a computer with subsequent automated production by a computer controlled machine tool. In 1971, Francois Duret introduced CAD-CAM technology to the field of dentistry. His idea was based upon the assumption that the technologies established in industry could be easily transferred to dentistry. The industrial use of CAD-CAM allows the production of any number of similar workpieces automatically, while saving time and manual effort. In dental medicine, however, this philosophy can not be applied due to the demands of the individual adaptation of the restoration design (one-of-a-kind production) to the patient.

The knowledge of normal salivary composition, flow and function is extremely important on a daily basis when treating the patients. Recognition should be given to saliva for the many contribution it makes to the preservation and maintenance of oral and systemic health. For fabrication of complete dentures, the anatomy and physiologic characteristics of the tongue and its environment must be evaluated thoroughly. Any abnormalities will jeopardize the success of such dentures. The tongue must engage in the normal physiologic acts of speech, mastication and deglutition and at the same time help stabilize the complete denture. Fabrication of the denture base and artificial tooth placement are important in aiding or hindering the tongue in accomplishing its tasks. The tongue is too mobile for one to make a useful impression of it, it is important for the patient¿s comfort and the stability of the dentures that when its musculature is relaxed, it should find itself in a cavity which at least gives it room to relax, otherwise it is like a confined prisoner with an attempt to stand upright resulting in immediate springing forward of the mandibular denture, when the teeth are separated.

The major block in oral health care of elderly and the residents would be the underestimation of the oral health care need by them. The dental care of the residents is often limited to emergency care and is not aimed at retaining teeth. Conversely, with changing attitudes the oral health goal should include: Keeping their teeth, keeping their teeth healthy and keeping their teeth pretty. The best option to serve the residents would be ¿home dentistry or domiciliary dental care,¿ however it is yet an infrequent practice in India.In everyday experience, one frequently speaks of a person as seeming older or younger than his chronological age, or of a person as being old in years but young in spirit. These comments do not imply that a man of 20 years cannot be distinguished from one of 40, or the man of 40 from one of 60 years. The findings indicate that aging is, to a great extent, an individual matter and that there are many facets to the aging process. The process of aging follows no clearly defined course of events by which it is possible to determine accurately the "age" of any individual.
