Keith J. The advantages to the dentalprofession of a successful effort in this direction are manifold. Themost important of these is that the use of a uniform terminologywould permit authors to discuss their concepts and techniques andbe sure that these would be understood by those who would readthe articles, regardless of the geographic location or the specialty ofthe reader. The need for a glossary of terms used in prosthodontics has beenrecognized for many years. Many new terms and words intended to describe orexplain modern philosophies or procedures have been added to thee1.
Authors, clinicians, and teachers have ascribed manydifferent interpretations and meanings to the same terms and words. Through the years, individuals, specialty groups, and the Bureau ofLibrary and Indexing of the American Dental Association havemade many sincere attempts to develop a standard and acceptablenomenclature in dentistry.
The Academy of Denture Prosthetics has studied the problemthroughout its existence and, until recently, has reached unanimousagreement on very few terms. This lackof progress was most discouraging, but three years ago it wasagreed by the Fellowship of the Academy that this Glossary wouldbe prepared, and that the majority opinion would be adopted. Thisdecision made possible real progress toward the ultimate goaldauniversal terminology for prosthodontics. At least sixteen outstanding prosthodontists have given serious study to each term included in thisGlossary.
The Fellows of the Academy of DentureProsthetics have combined their efforts to serve as lexicographers. The chief role of a lexicographer is to record the current usage ofwords. The chief function of words in science is to convey meaning. The lexicographer has a duty to lead as well as to follow. Whereclearness demands it, he should place such restrictions as arenecessary to avoid ambiguity.
Where more than one term is used toexpress the same idea or concept, he should indicate the preferenceon the basis of logic and other considerations. Certain terms were determined to beobjectionable for some reason and are marked Obj. These decisions were made on thebasis of majority opinion.
It is hoped that eventually obsolete orobjectionable terms and terms which tend to mislead and confusewill be eliminated entirely. Constructive suggestions are invited, and these will be giventhorough consideration in future editions.
In its present form, thisGlossary can serve as a good temporary standard. The Fellows of the Academy ofDenture Prosthetics have supplied the fundamental informationand have made the necessary decisions.
