Abstract
The stability of the anchorage unit plays an important role in orthodontic tooth movement. Controlled orthodontic tooth movement, such as retraction or intrusion, is difficult to achieve without causing undesirable movement of the anchorage unit. This article describes characteristics, surgical procedure, and clinical use of the Spider Screw® (HDC Company, Sarcedo, Italy, hdc@goldnet.it), as a nondental and noncooperation-based anchorage system.
