Ms. Block et Dr. Hoffman, A NEW DEVICE FOR ABSOLUTE ANCHORAGE FOR ORTHODONTICS, American journal of orthodontics and dentofacial orthopedics, 107(3), 1995, pp. 251-258
A new device has been designed to provide anchorage for orthodontic to
oth movement. It is a disk, textured and hydroxylapatite coated on one
side, with an internal thread on the other side. It is placed on pala
tal bone and, after integration, can be connected to teeth for anchora
ge. This article reviews a dog study demonstrating unilateral tooth mo
vement towards the ''onplant'' and a monkey study mimicking its use to
anchor the molars for anterior retraction.
