Heimisdottir, K; Pjetursson, BE; Ruf, S; Gebauer, U; Lang, NP (2006). The role of circumferential fiberotomy in enhancing orthodontic stability. In: Pan European Federation of IADR (PEF 2006). Dublin Ireland. September 13-16, 2006.
Objectives: Circumferential septal fiberotomy (CSF) following orthodontic treatment has been propagated to improve stability and prevent relapse of tooth alignment. The hypothesis of no difference between performed CSF and controls was tested. Methods: In 9 consecutively admitted patients at the end of orthodontic tooth alignment, the lower arch-wire was removed. CSF was performed from the mandibular canine to the central incisor on a randomly chosen side, while the contra-lateral side served as unsurgerized control. At baseline and every 4 weeks up to 6 months, study casts were taken and 1) analyzed using the Irregularity Index (II)according to Little and 2)photographed, traced and superimposed digitally. The translational and rotational movements of teeth as well as gingival parameters were analyzed as well. Results: By using the II and by superimposing the tracings, no statistically significant differences were found between the test (CSF) and control sides for any parameters. Moreover, CSF did not impinge on the gingival tissues. Conclusion: Since CSF did not improve stability of orthodontically aligned teeth nor prevent relapse during the healing pahse of up to 6 months, CSF should not be recommended following orthodontic therapy.
