This latter plan will be found Fig. 46. useful in moving outward or inward a single molar, which is sometimes desirable in order to establish perfect occlusion. CHAPTER VII. PRACTICAL CASES. Section I. Having completed the description of the principal ways of constructing and adjusting the appliances for moving and retaining the teeth, some practical cases are appended to familiarize the reader with this system, and enable him to more easily comprehend its intelligent employment. Such simple cases as are found in early childhood will be first cited. There is prob- ably no limit as to the time at which the treatment of dental irregularities may be commenced. Cases treated so late as at sixty years of age have been reported; but I am more and more impressed with the great advantages of beginning the treatment early, just as soon as the appearance of irregularities is manifest and the teeth have emerged from the gum sufficiently to admit of banding.
