Abstract
 
 Objective: The current randomized clinical trial aimed toevaluate the use of direct miniplates anchorage in conjunction with the Forsus Fatigue Resistant Device (FFRD) in treatment of skeletal Class II malocclusion. 
Material and Methods:48 Class II femaleswere randomly allocated to either the conventional Forsus (FFRD) group (16 patients, mean age 12.1±0.9years) Forsus with miniplates (FMP) group (16 patients, mean age 12.5±0.9 years), or untreated control group (16 subjects, mean age 12.1±0.9 years). After the leveling and alignment stage, miniplates were inserted in the mandibular symphysis in the FMP group. FFRD was inserted directly on the miniplates in the FMP and onto the lower wire in the FFRD group. The appliance was removed after reaching an edge to edge incisor relationship. Results: The effective mandibular length significantly increased in the FMP group only (4.05±0.78).no significant differences were found in the maxillary dimensions. The upper incisors retroclined in the FFRD and FMP groups with no difference between them. The lower incisors showed a significant proclination in the FFRD group (9.17±2.42) and non-significant retroclination in the FMP group. Soft tissue parameters were improved in both treatment groups. Conclusion: 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 unfavorable proclination of the lower incisors was evident with the conventional FFRD but was successfully eliminated with the miniplates anchorage.
