Book excerpt: Excerpt from Transactions of the Illinois State Dental Society: At the Twenty-Ninth Annual Meeting, Held at Rock Island, May 9 to 12, 1893 In a few cases I have seen solid fillings in such dovetails stretched by the force Of mastication sufficiently to allow the main portion Of the filling to leave the buccal and lingual walls of the cavity and thus destroy the filling. For this reason I Often fill these anchorage slots with platinum gold when a very heavy filling is to be supported. Judging from close Observation directed to this point I am of the Opinion that platinum gold well welded and con densed will bear from one-third to one-half more strain than pure gold in such positions. The anchorage slot can therefore be that much smaller and give the same support, and the cusps of the tooth need not be weakened by so deep a slot. In cases in which the buccal and lingual Wall's, one or both, are thin and frail, so that a portion Of the wall Of the cavity becomes liable to breakage by catching some hard substance upon it, it should be cut away sufficiently to build the gold over its margin in such a way that the strain will come upon the filling itself instead of the wall. This part Of the filling should be carried sufficiently far that nothing can catch upon the margin Of the frail wall and also the filling material should be thick enough so that it will not be crushed by the strain Of mastication. A very thin layer Of fill ing material over such a wall is worse than useless, for it is likely tobe crushed against the wall in such a way as to break it down. In this paper I have said nothing about the anchorage Of fil lings in cases where the pulp has been removed. In all Of this class the more direct subject for discussion would be the conserva tion Of frail walls, a distinct subject in itself.
