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.

Introduction and Aim: Various functional appliances are developed to remodel the glenoid fossa and, thereby change the position of the mandible and correct Class II malocclusion. Many diagnostic aids have already been used to evaluate the changes ,but Cone Beam computed tomography (CBCT), three -dimensional diagnostic tool is rarely used .So this study was conducted with an aim is to evaluate the changes seen in the temporomandibular joint (TMJ) after mandibular advancement in class II malocclusions with functional appliance therapy, using CBCT, and also to assess and compare the efficacy of Twin Block, Power Scope and Forsus Fatigue Device used for the correction of class II malocclusion.Materials and Methods: The retrospective study was performed using the 52 CBCT scans of 26 patients with class II malocclusion due to retrognathic mandible. The subjects were divided into three groups based on appliance (Twin Block, Power Scope and Forsus Fatigue Resistant Device) used for the treatment. The changes seen in TMJ after mandibular advancement and condylar response to functional therapy was evaluated using the six. Data obtained were subjected to one-way Anova analysis with Posthoc Tukey test. Software SPSS version 20 was used to analyse the data. The level of significance was set at p < 0.05.Results: In subjects treated with Twin Block, the condyle was displaced slightly downwards and anteriorly; and condylar height was reduced. The decrease in the anterior and superior joint spaces were also found. In subjects treated with PowerScope and Forsus Fatigue Resistant Device, there was an increase in condylar height and width with a decrease in anterior and superior joint space.Conclusion: All three appliances were found to bring about changes in TMJ structures, but amongst them the Twin block has proved to be more efficient.

ABSTRACT Introduction: Fixed functional appliances are non-compliant solutions to Class II malocclusion treatment. The clinician, however, should be careful of unexpected complications during the therapy. Methods: 58 female adolescents who presented with Class II malocclusion due to deficient mandible were treated with Forsus Fatigue Resistant Device (FFRD) therapy until an overcorrection to an edge to edge incisor relationship was achieved. Results: Incisor relationship and overjet were corrected successfully in all the subjects. Twenty-two patients had a complications-free treatment, while several complications were encountered with the remaining 36 subjects. In particular, mandibular canine rotation and development of posterior crossbites were the most common complications, with percentages of 51.7% and 25.9% respectively. Other complications included the breakage and shearing of the extraoral tubes of the first molar bands, and excessive intrusion of the upper first molars. Conclusions: FFRD is an efficient appliance for treatment of Class II malocclusion; however, different complications were encountered during the appliance therapy. A focus on taking precautions and applying preventive measures can help to avoid such problems, reducing the number of emergency appointments and enhancing the treatment experience with the appliance.

Treatment of class II malocclusion requires accurate diagnosis and treatment planning. This case report outlines the successful management of a growing skeletal class II using Forsus fatigue resistant device for correction of skeletal parameters and premolar extractions for correction of dental parameters. The patient’s profile improved significantly with a 4° reduction in ANB angle. An ideal overjet, overbite and molar relation were also attained.

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.

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.
