The primary goal of complete dentures is the functional restoration of lost esthetics, mastication and pronunciation.
Although the dentist is well aware of the necessity for taking an accurate impression, it seems that in reality he endeavors to fabricate complete dentures that are not sore, are stable, and chew well. Unlike crown and bridge impressions, complete denture impressions are more difficult since they demand functional considerations. We therefore arrive at the theory that we are making impressions, not taking them.
No matter how accurate the impression of the oral cavity, and how well it is recreated in the model, it is probably nothing more than just an outline. No matter how well the patient's outer appearance is restored, the impression is not good if the denture feels loose during mastication and when talking. That is to say, the dentist must be conscious of his intended goals when taking the impression.
The functional complete denture adjustment technique (dynamic impression) is not a particularly difficult or special technique. The impression, interocclusal registration, arrangement of the artificial teeth, and even the try-in of the wax denture are carried out by the operator's own methods. After that it is only necessary to fabricate a complete denture that in is harmony with and accommodates the body's masticatory system by using Hydro-Cast, which incorporates tissue treatment capacity, for a dynamic impression.
This is a report of my clinical knowledge gained from the functional complete denture adjustment technique applying the above methods.

Advancements in the articulator have gone hand in hand with the progress of our times. Just as iron has brought prosperity to modern culture, the appearance of new materials has created new technology, and the confirmation of scientific theory has followed.
The founding of the California Gnathological Society and the appearance of the Stewart articulator must be considered events defining this era. Stewart and his articulator brought know-ledge of occlusion to the world, and created the era of full mouth reconstruction. Slavicek, Kulmer and Gausch are now doing research using the SAM system to elucidate the relationship of occlusion and the temporomandibular joint.
In this report I will discuss the special features of the axiograph and the SAM2 articulator, as well as how to take dynamic records of mandibular movements and how to carry out diagnosis.

In part one I considered projections based on various data about what type of effects the advent of the aging society would have on our future.
In part one I found:
1. The aging society and social security
Although about six workers are currently needed to maintain the living standards of one elderly person over 65 years of age, in the future this ratio will be only two workers for one elderly. As a result, the costs for pensions, taxes and social security will increase three fold. In an environment like this it is unreasonable to expect that our remuneration from the social insurance system, which forms the basis of our livelihood, will be revised upward on a sliding scale with commodity prices and wage rates.
2. The problem of medical treatment costs
The rate of increase in medical treatment costs for the elderly has been especially steep, the precipitous increase in these costs has put pressure on the national finances, and investigations have been initiated into making fundamental reforms in the system of medical insurance.
3. The increase in the number of dentists
Based on the latest information available, it has been projected that even though we cannot expect any increase in the population, there will be a two fold increase in the number of dentists by the year 2, 025 since there are currently about 3, 000 new graduates each year.
In part two I would like to discuss certain accomplishments made at this clinic where we have been attempting to deal with these problems over the past several years.
