American Association of Orthodontists 112th Annual Session Honolulu, Hawaii – May 4-8, 2012 Forsus™-RME Combination (FRC) - a non-compliance-multifunctional-onephase device

American Association of Orthodontists 112th Annual Session Honolulu, Hawaii – May 4-8, 2012 Authors: Werner Noeke Raphael Hoehr – private office, Meschede, Germany Tim Noeke – University of Muenster, Germany Kathrin Weyer – University of Frankfurt, Germany

Purpose: For an improved patients and orthodontists comfort the Forsus™-Spring can be used in place of the Herbst Device in combination with the RME. Compared to the stiffness of the Herbst, the main advantage is its flexible construction and the quick incorporation.

Material: The FRC-appliance consists of RME-screw, solded lingual archwire, Forsus™-Spring and vestibular sectional arch. The FRC has the advantage of less breakage, less tissue-irritation and lab/chair-time, no screws, comfortable wearing and adjustment. In comparison to the Herbst Device, only palatal and lingual solding is necessary.

Adding a full-arch multibraces system is easy e.g. needed in class II,2. Therefore all 8 bands of the FRC may remain in place.

19.07.2011 10 weeks later the upper jaw was aligned and the upper incisors were proclinated to unlock the lower jaw. The Forsus Spring was attachted. 19.07.2011 19.07.2011

22.11.2011 After 4 months a Cl. I relationship at the canine has been established, so the forsus spring could be removed. 22.11.2011 22.11.2011

The whole treatment time is about 12 - 15 months. The FRC gives an exceptional advantage combining a non-compliance class II correction in one-phase treatment with multibraces which leads to a short treatment time.
