Excerpt from Orthodontia and Orthopaedia of the FaceIn 1887 I presented a simple wire device for the regulation of teeth which I termed a Crib.* The anchorage was gained by extending a Spring-wire on the lingual and labial sides of the teeth near the gum, in some cases including all of the teeth, in others only a part of those in the arch, the spring on the labial and lingual sides was connected by passing wires over the arch at the junction of the teeth. Later I devised the Jackson system described. The anchor age is secured by spring-clasp attachments and partial-clasps, sup porting a base-wire, to which any form of spring can be added.The introduction of a new system necessitates new names, but an effort has been made to use those that will be readily understood, avoiding overfull descriptions and unnecessary technical terms.In some of the chapters descriptions of a few well-known methods that have been used successfully by the profession are included. These are presented in order to assist practitioners who are using those methods and who are not yet familiar with the system of anchorage advocated in this work. The book contains four hundred and fifty pages of text, thirty-four insets, and an appendix including descriptive matter and forty-four page plates illustrating apparatus that has been used. There are in all eight hundred and one cuts, seven hundred and sixty Of which are original with me.Orthodontia has grown in importance until it has become a specialty of dentistry. It is engaging some of the most active and original minds in the profession. Opinions have been recorded, theories advanced and contested, until the literature of orthodontia has attained a volume proportionate to the importance of the subject.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
