Aim: The present study evaluates the feasibility of the "FAMI"-screw as a bone anchorage in orthodontic treatment. Material and methods: In 12 patients 17 bone screws were implanted under localanaesthesia in the vestibular aspect of the alveolar process with an immediate loading. In eight cases a tooth space was closed by mesialisation of a molar, in three cases intrusions of upper or lower incisors were carried out. Results: Two screws which had to be placed into the mobile part of the gingiva were removed earlier due to infection. All the other screws were stable until the end of the treatment period. In all cases unintended movement of tooth were avoided. Conclusion: The use of the "FAMI "-screw as bone anchorage in the course of orthodontic treatment appears to be effective and represents an alternative to established orthodontic implantat systems Keywords: FAMI-Schraube, Knochenverankerung, Kieferorthopädie
