Not illustrated. 1916 Excerpt: ...to the various tooth movements as was the Angle arch. As stated before, the plain arch which was used in the retraction of the upper anterior teeth, may be said to be the forerunner of the modern expansion arch. In the plain arch, we have a long spring which is an ideal appliance for exerting force upon the lateral halves of the arches by means of reciprocal anchorage. With occipital anchorage, it was possible to accomplish good results in a certain number of cases, namely, Class II, Division 1. However, these results were not ideal, and in the treatment of Class I cases with its various types, and Class II, Division 2, and Class III cases, various combinations of appliances were used and the results were not always ideal. By threading the ends of the plain round arch and putting on the nut, we have an appliance which combines the force of the spring lever and the jack-screw. Then with the improvement of intermaxillary anchorage, it became possible to accomplish better results than had ever been accomplished before. With the proper adjustment of the arch and the addition of a few devices for the movement of the roots of the teeth, the results which can be accomplished are only limited by the ability of the operator. Fig. 120. Angle's ribbed expansion arch. The expansion arch as designed by Angle possesses a patented nut with a friction sleeve, as shown in Fig. 119, which slips in the end of the tube on the molar band. The round end of the nut fitting in the tube prevents the cheeks from working the nut loose. In order to be of any benefit the round end of the nut must fit the tube closely. Another feature of some of the Angle arches is the making of a small rib into which notches can be filed (Fig. 120) which prevents the ligatures from slipping on the arch...
