摘要
Ninety-nine young male Sprague-Dawley rats were used in a study of dimensional and metabolic changes incident to the placement of elastic bands between the maxillary first and second molars. Several conventionally accepted hypotheses on the nature of tooth movement changes were not confirmed. An attempt has been made to account for the differences between our observations and those of previous workers, and a testable alternative hypothesis has been proposed. © 1969 The C. V.
