Invisible retainers

      A review of the literature provided surprisingly little historical information of value on retainers. This dearth of material in the literature indicates that, although many innovations have been made by persons in the profession, few busy practitioners find time, encouragement, or facilities to publish them. As a result, the present article reports in detail the findings of earlier investigators and describes the technique used in the production of invisible retainers. When an orthodontist or other specialist perfects this method, he will find it a rewarding, time-saving and valuable addition to his treatment procedures.
