Comparison Of Soft Tissue Treatment Changes between Twin Force Bite Corrector and Forsus Fatigue Resistance Appliance

Objective: The aim of this study was to compare the soft tissue changes after two fixed functional appliances Twin Force Bite Corrector and Forsus Fatigue Resistant Device treatment in patients with Class II division 1 malocclusion. Materials and Methods: The sample consisted of 28 lateral cephalograms of 14 young adolescent patients, divided into two groups. Group 1 consisted of 7 patients treated with fixed functional appliances associated with fixed appliances, Twin Force Bite Corrector and initial mean overjet of 6.83 mm. Group 2 comprised 7 patients treated with fixed functional appliances associated with fixed appliances, Forsus Fatigue Resistant Device and initial mean overjet of 7.01 mm. t-Tests were used to compare treatment changes and the final cephalometric statuses between the groups. Results: According to the results, there was no intergroup difference regarding the soft tissue changes. Conclusion: Young adolescent patients treated with both the fixed functional appliances present similar soft tissue results. It is the clinician choice to select the appliance pertaining to the type of patient he is treating. Clinical Significance: Since there is a paradigm shift of considering the soft tissue profile for orthodontic treatment planning, assessing the soft tissue changes is the new scope of research.
