Recognition of these types by the orthodontist is important to obtaining successful results in treatment. Fig. 23-14 in the chapter on midfaceretrusion shows pre- and postoperative photographs of a case which would have benefited more from palatal expansion and mesial tooth movement by orthodontic treatment. The decision as to whether surqery, orthodontics, or a combination of both is best for a patient under consideration has not been discussed sufficiently in this text, which otherwise contains a wealth of information for the orthodontist.

The amount of maxillary change is of the order of 1 or 2 mm., and this is largely cancelled by a similar change in the anterior part of the mandible as a result of rotation. In severe skeletal discrepancies, it is likely that a surgical approach will be more satisfactory. The evidence would confirm that it is not possible to change the anteroposterior position of the mandible to any meaningful extent by orthodontic means only. The changes which are produced by appliances are confined to the teeth and the alveolar bone which supports them. This is best carried out at a time when active growth is taking place, and we are able to some extent to redirect the growth not of the basal bone but of the alveolar process.

If vertical loading associated with the antirotative movement created in the antirotative type of buccal tube is exerted, the upper first molar and the maxillary bone can be depressed vertically to the occlusal plane without rotation. The presence of a buccolingual deviation between the locations of the centers of resistance of the upper first molar and the maxillary bone was detected. Loadings with the antirotation type of buccal tube and the solid inner bow used in this experiment were successful in reducing buccal rotation of the upper first molar and the maxillary bone.
From a letter sent June 17, 1937, to Dr. J. A. Salzmann by Dr. John V. Mershon, who was the first to direct attention to the biologic entailments in orthodontic practice: “Development is a series of correlated events which constantly modify the interrelated tissues as the result of growth processes. Development of one part depends upon the development of another part and the whole elaborate process is beautifully synchroniied.
