Forsus Fatigue Resistant Device

ABSTRACT Objectives To evaluate the use of the Forsus Fatigue Resistant Device (FFRD), supported with bimaxillary splints, in treatment of skeletal Class II malocclusion. Materials and Methods Data from 46 skeletal Class II females who received either conventional Forsus alone (FFRD group) (15 patients, 12.54 ± 0.90 years), FFRD and bimaxillary splints (splint-FFRD group) (15 patients, 12.29 ± 0.82 years), or were untreated controls (16 subjects, 12.1 ± 0.9 years) were retrieved from previous clinical trials. FFRD was inserted onto the mandibular archwire in the FFRD group after leveling and alignment with multibracket appliances. In the splint-FFRD group, Forsus was inserted between fixed maxillary and mandibular splints. Treatment continued until reaching an edge-to-edge incisor relationship. Results Both treatment groups failed to induce significant mandibular skeletal effects compared to the normal growth exhibited by untreated controls. The splint-FFRD group showed significant reduction of SNA (−0.88° ± 0.51°) and ANB (−1.36° ± 0.87°). The mandibular incisors showed significant proclination in the FFRD (9.17° ± 2.42°) and splint-FFRD groups (7.06° ± 3.34°). Conclusions The newly proposed splint-supported FFRD was equally effective as the conventional FFRD in treatment of Class II malocclusion with dento-alveolar changes and additional maxillary restricting effect. It has an additional advantage of immediate initiation of the Class II correction.

ABSTRACT Objectives: To evaluate the use of direct miniplate anchorage in conjunction with the Forsus Fatigue Resistant Device (FFRD) in treatment of skeletal Class II malocclusion. Materials and Methods: Forty-eight females with skeletal Class II were randomly allocated to the Forsus plus miniplates (FMP) group (16 patients, age 12.5 ± 0.9 years), Forsus alone (FFRD; 16 patients, age 12.1 ± 0.9 years), or the untreated control group (16 subjects, age 12.1 ± 0.9 years). After leveling and alignment, miniplates were inserted in the mandibular symphysis in the FMP group. The FFRD was inserted directly on the miniplates in the FMP group and onto the mandibular archwires in the FFRD group. The appliances were removed after reaching an edge-to-edge incisor relationship. Results: Data from 46 subjects were analyzed. The effective mandibular length significantly increased in the FMP group only (4.05 ± 0.78). The mandibular incisors showed a significant proclination in the FFRD group (9.17 ± 2.42) and a nonsignificant retroclination in the FMP group (−1.49 ± 4.70). The failure rate of the miniplates was reported to be 13.3%. Conclusions: The use of miniplates with the FFRD was successful in increasing the effective mandibular length in Class II malocclusion subjects in the short term. The miniplate-anchored FFRD eliminated the unfavorable mandibular incisor proclination in contrast to the conventional FFRD.

ABSTRACT Objective:  To detect three-dimensionally the effects of using mini-implant anchorage with the Forsus Fatigue Resistant Device (FFRD). Materials and Methods:  The sample comprised 43 skeletal Class II females with deficient mandibles. They were randomly allocated into three groups: 16 patients (13.25 ± 1.12 years) received FFRD alone (Forsus group), 15 subjects (13.07 ± 1.41 years) received FFRD and mini-implants (FMI group), and 12 subjects (12.71 ± 1.44 years) were in the untreated control group. Three-dimensional analyses of cone beam computed tomographic images were completed, and the data were statistically analyzed. Results:  Class I relationship and overjet correction were achieved in 88% of the cases. None of the two treatment groups showed significant mandibular skeletal effects. In the FMI group, significant headgear effect, decrease in maxillary width, and increase in the lower facial height were noted. In the FMI group, retroclination of maxillary incisors and distalization of maxillary molars were significantly higher. Proclination and intrusion of mandibular incisors were significantly greater in the Forsus group. Conclusions:  FFRD resulted in Class II correction mainly through dentoalveolar effects and with minimal skeletal effects. Utilization of mini-implant anchorage effectively reduced the unfavorable proclination and intrusion of mandibular incisors but did not produce additional skeletal effects.

Lip Bumper

Patients with a skeletal class II malocclusion are usually associated with a prognathic maxilla with orthognathic mandible or a retrognathic mandible with orthognathic maxilla or a combination of both. Patients with severe prognathic maxilla are usually associated with increased overjet which results in a lower lip trap. The lip trap should be managed the earliest as it will lead to further proclination of the upper anterior teeth and also hinder the normal growth of the mandible. To overcome the limitations of a conventional lip bumper, we arrived at an idea of fixed lip bumper supported using mini-implants.

A deficient mandibular growth on the sagittal plane is the most frequent diagnostic finding in dentoskeletal Class II malocclusion. Evidence indicated that functional treatment for such malocclusion is efficient only if performed during the pubertal growth spurt, as identified through radiographical growth indicators. With the aim of reducing the radiation to the patients and to follow longitudinally individual growth phases, the use of the sole third finger middle phalanx maturation (MPM), as a 5-stage method, has been proposed. Herein, three clinical cases of skeletal Class II malocclusion in growing patients treated by removable functional appliances (with or without full-fixed appliance treatment) are reported. Timing of intervention was strictly planned according to the MPM method, and skeletal effects have been recorded up to 21 months of follow-up. In all the cases, noteworthy skeletal effects have been achieved in terms of mandibular elongation, with relevant occlusal and aesthetic outcomes. It has also been showed that results are stable or slightly improved after functional treatment. These results would be achieved irrespective of the appliance used and support the use of the MPM method in everyday clinical practice.

Abstract Introduction The purpose of this study was to evaluate and compare the skeletal, dentoalveolar and soft-tissue effects of 2 fixed functional appliance; Forsus Fatigue Resistance Device (FFRD) and PowerScope appliance in treating patients with skeletal class II division 1 malocclusion. Materials and Methods This comparative prospective two-group study included 20 patients with a mean age of 11.2 ± 1.6 years with skeletal class II malocclusion with retrognathic mandible. One group was treated with FFRD, and second group was treated with PowerScope appliance. Lateral cephalograms were evaluated at T1 (pre-functional appliance treatment)) and at T2 (postappliance treatment). Cephalometric values were calculated and assessed to evaluate skeletal, dentoalveolar and soft-tissue changes. Results Sagittal correction of class II malocclusion appeared to be mainly achieved by dentoalveolar changes in the PowerScope group. The FFRD was able to induce both skeletal and dentoalveolar changes. A favorable influence on facial convexity was achieved by both groups. A significant increase in upper pharynx and lower pharynx dimension was seen in the PowerScope group. A statistically significant decrease in upper lip protrusion, increase in lower lip protrusion, increased nasolabial angle, and decrease in inferior labial sulcus were noted in both the groups. Lower incisors proclined more in the PowerScope group. Conclusion Both appliances were effective in correcting class II malocclusion. Forsus had more skeletal effects on the mandible, whereas PowerScope had less skeletal effects on the mandible and more dentoalveolar effects, contributing to class II correction. Both groups showed a significant improvement in soft-tissue profile. PowerScope group showed a significant increase in airway dimensions

Treatment Alternatives

Class II malocclusion has a high incidence in the population, which may compromise smile aesthetics, occlusion function and stability. Skeletal Class II may affect facial aesthetics and upper airway volume. Class II malocclusion is routinely associated with skeletal Class II condition, having as treatment alternatives the use of Extra Buccal Appliance (EBA) or removable or fixed propulsor appliance. This article describes a case of a patient who did not accept the use of EBA and so it was fitted a Flex Developer propulsor for Class II correction and discussed the advantages and disadvantages of therapeutic alternatives for Class II correction.

Accurate Picture

Analysis of sagittal jaw relationship is important in orthodontic diagnosis and treatment planning, and can be investigated by angular or linear parameters. In the present study an analysis was performed using profile cephalograms of 40 children with skeletal Class II malocclusion. A correlation analysis is presented, involving five different methods of expressing sagittal jaw relationships. Whilst some degree of agreement could be noted, it was not possible to suggest a pair of measurements, which in combination, could give a more accurate picture of sagittal jaw relationships.
