Technic and scope of cast gold and porcelain inlays; with a chapter on endocrinodontia, or the ductless glands - their expression in the human mouth . ing in a box seat; inother words, the cavity is one presenting the apixarance of asimple one in every surface but the floor; here is found a devia-tit)n in that floor, instead of conforming in shape to the sur- 78 CAST (lOLI) AXl) IXLAYS face 111)011 wliicli it presents, slopes to l)eeoiiie an inclined planeto offer the reqnired resistance to displacement dnriiio- stressof mastication. The incline slionld be sharp and well defined;a step may ])e nsed, hnt an incline tends to l)etter conservationof the tooth. In teeth snl)ject to stress, from and in more than one di-rection, these lines of stress must be carefully studied, and aninclined plane must be formed upon the floor of the cavity too])i)ose each line of direction of stress. In cases where the cusps are very deep, and where the man-(lil)le enjoys a limited laterorotary motion, thus subjecting themolar teeth to a considerably greater amount of laterorotarystress than Avould be the case if the motion of the mandible were.
