Some Fundamental Factors in the Construction of Efficient Dentures

A new era, comparable to the one which began with Bonwill, had its beginning with the publication of Dr. Gysi's articles on "The Problems of Articulation," in the Dental Cosmos of 1910. Added impetus was given the study of denture construction when, in 1913, he visited New York City and enabled teachers and students from widely distributed points in the United States and Canada to do practical work under his supervision. Since that time no one has successfully controverted the theory of the factors which he enunciated as essential to the construction of an efficient denture. Many men with laudable enthusiasm and scientific trend of mind have swept the student dentist off his course with theories based on assumptions or, if you please, truths, which have proved valid in innumerable instances but which are inadequate and too arbitrary where conditions do not approach the average case. This is not to be regretted, since invaluable contributions have been made, and the dentist with his new articulator-his new plaything-took a renewed interest in the entire procedure of constructing dentures. These endeavors of inventor and disciple served to establish more firmly the true principles, and aided in developing a technique which has improved the old method of adapting the articulator to the individual requirements. In this process of development he has learned among other things to approach his patients with the consummate skill of a practical psychologist and thereby secure an indispensable factor, namely, the cooperation of the patient. With this cooperation he is able to supply successful masticatory substitutes because he enables the patient to realize the conditions required for the successful wearing
