Diverse treatment options are available ranging from utility arches, intrusion arches, headgears, surgical methods to the more recent mini-implants. The intricacies associated with the various intrusion mechanics have been elaborated. Это и многое другое вы найдете в книге The Mechanics of Intrusion
