Publisher's Synopsis
Excerpt from Extraction of Teeth
Sides, by altering the curvature, ruins the forceps and renders them useless.
Two other pairs of forceps may occasionally be needed, perhaps once in two or three years, for removal of a buried root, where the crowns of the teeth on each side of it have come so close together that they would be damaged by the forceps in general use. An expert extractor can quite well use the lower forceps for an upper root, and so the one represented in fig. 4 (74n) is sufficient, but it is better to have its fellow for maxillary roots, no. 147 (fig.
It is well to have four mouth props, and none are better than a modification of the aluminium props designed by Sir Frederic Hewitt. The experience Of several years has proved that these props are equally efficacious and secure, if the ends are about half the size Of Hewitt's, and mine are by g and the height corresponds to Hewitt's nos. I, 2, 4, 5. Not only are both ends of Hewitt's props greatly reduced in size, but the Oblique end is SO shaped that for half its length it is parallel to the Opposite end. This allows the prop to be equally stable whether placed between the cheek teeth or in its usual-place between the incisors.
