Arrangement of artificial teeth in abnormal jaw relations: Mandibular protrusion and wider lower arch

Abstract

The arrangement of artificial teeth is an art based upon the biomechanical factors governing the ultimate success of the dentures. An understanding of the interplay of these factors is, therefore, an important aspect of the whole procedure of setting the teeth. Although guiding principles are laid down for the various steps, it is, at times, difficult to adhere to these in individual situations. This is especially true when the abnormality of the jaw relations is very marked. In such patients, various deviations from the set rules may be necessary to obtain a successful arrangement of the teeth. A student of prosthodontics has to be conscious of this fact and should be able to introduce necessary changes wherever they are indicated, while developing a workable arrangement of teeth on the articulator. Only then will he be able to cope with the various abnormalities of jaw relations with which he will be faced in his day-to-day clinical work.
