Tomographic evaluation of dentoskeletal changes due to the treatment of class II malocclusion with Forsus appliance

AbstractPurposeThis study evaluated dentoalveolar skeletal changes promoted by the Forsus appliance, associated to fixed orthodontic appliance, in the correction of Class II, division 1 malocclusion, from Computed Tomography (CT).Methodssample consisted of 10 youngsters (7 males and 3 females), with...

Description
Summary:	AbstractPurposeThis study evaluated dentoalveolar skeletal changes promoted by the Forsus appliance, associated to fixed orthodontic appliance, in the correction of Class II, division 1 malocclusion, from Computed Tomography (CT).Methodssample consisted of 10 youngsters (7 males and 3 females), with a mean age of 13.86 years. Two Forsus ® models were installed after the alignment and leveling phase of the teeth. Two tomographic images of each patient, T1 and T2 (initial and immediately after removal of Forsus ® appliance) were done to perform the anatomical tracings and obtain the variables of interest. The data were described by means and standard deviations. For the comparison between the initial and final phases, the paired “t” test was used and a significance level of 5% was considered (p < 0.05). Resultssmall skeletal changes were observed, such as posterior maxillary displacement and a slight mandibular growth. Larger dentoalveolar changes occurred as extrusion, retrusion and lingualization of upper incisors; Intrusion, protrusion and vestibularization of the lower incisors; Mesialization and extrusion of lower molars.ConclusionConsidering the patients evaluated in this study, Forsus ® presented similar results to other mandibular propulsion appliances, with dentoalveolar effects that favored Class II correction, however, with very slight skeletal modifications.
