Aims: Evaluation of the effectiveness of orthodontic treatment of Class II malocclusion with the Twin-block appliance in children withβ-thalassemia major. Methods: The study was conducted with 49 patients with Class II malocclusion aged 10-14 years. The control group included 23 healthy patients. The main group included 26 patients with β-thalassemia major. Patients had received orthodontic treatment with a Twin-block appliance. The duration of orthodontic treatment was 1.5–2 years. Results: In both groups, a statistically significant increase in the SNB angle was observed. Subsequently, the ANB angle was normalized. The effective length of the maxilla growing and mandibular length increasing was observed. Overjet distance is decreased due to favorable torque changes. Pretreatment assessment revealed that overbite was smaller in children with β-thalassemia major. As the effect of orthodontic treatment, statistically, significant changes were observed on both overjet and overbite distances (p <0.001). Conclusions: Orthodontic treatment of β-thalassemia major of patients with Twin-block appliance in mixed dentition stage is effective in improving inter arch relationships and the orofacial functions.

This study aimed to evaluate and compare the dentoalveolar effects of the myofunctional trainer T4KTM versus twin block in children with class II division I malocclusion. Two parallel arm randomized comparative clinical trial was conducted, including twenty healthy children, 9–12 years old, showing Angle’s class II division I malocclusion due to mandibular retrusion. Children were randomly assigned into two groups according to the appliance used; Group 1: T4k, and Group II: twin block. Follow-up was done every 4 weeks for 9 months. Postoperative cephalometric X ray, study casts and photographs were taken for measurements and comparison. T4K showed a statistically significant reduction in the overjet (−2.50 ± 1.00 mm) (p < 0.0001), and a significant increase in the lower arch perimeter (LAP) (1.19 ± 0.96 mm) (p = 0.01). The twin block showed a statistically significant reduction in the overjet (−3.75 ± 1.10 mm) (p < 0.0001), a significant reduction in the overbite (−16.22 ± 17.02 %) (p = 0.03), and a significant increase in the LAP (1.69 ± 0.70 mm) (p < 0.0001). The overjet showed a higher significant decrease in the twin block group than in T4K (p = 0.03). The mean values of the overbite were significantly decreased in twin block than in T4k (p < 0.0001). Both groups showed significant dentoalveolar improvements toward class I occlusion; however, the twin block showed significantly better results than T4K appliance.

ABSTRACT The primary concern of the patient as well as their parent seeking orthodontic treatment is the sagittal relationship of the dentition and jaws. Twin block is the most common functional appliance used successfully in correction of growing patient with skeletal class II malocclusion. However, the method of using extraoral traction in combination with twin block appliance (twin block traction technique) is to reinforce the functional component for correction of a class II sagittal relationship. A 12-year-old male patient reported to the Department of Orthodontics with a chief complaint of forwardly placed upper front teeth. With the help of clinical examination, cephalometrics, and diagnostic records, the diagnosis of the patient was confirmed as skeletal class II maxillomandibular relationship with prognathic maxilla and retrognathic mandible with a vertical growth pattern. The patient was treated with twin block appliance along with headgear. The appliance design and postfunctional results are demonstrated in the following case report. Although twin block with high-pull headgear is known to produce favorable results in mixed dentition, the same was observed in permanent dentition during growth phase. Combination of twin block appliance with high pull headgear gave the desired results. How to cite this article Daga PN, Karandikar GR, Ravindranath VK, Doshi S.

The aim of orthodontics treatment is normalization of teeth position in three planes, using various orthodontics appliance to reach the chepalometric standar and normal occlusion. Orthodontic treatment for dentoskeletal class II division 1 malocclusion in growing patients using myofunctional appliance may correct anteroposterior planes of mandibula. This study was a descriptive retrospective analytic study to look at the success of Orthodontic treatment for dentoskeletal class II division 1 in growing patients with myofunctional appliance using chepalometrics analysis Steiner value. The sample used in this study is chepalogram radiographic from patient with dentoskeletal class II division 1 malocclusion in growing patients before and after using myofunctional appliance in PPDGS orthodontics Clinic of Padjadjaran University. Statistic analysis were performed with pair t-test and Wilcoxon. Based on this study, it is concluded that orthodontic treatment with myofunctional appliance such as activator and twin block in growing patient with dentoskeletal class II division 1 malocclusion shows significant changes and compatibility with the normal criteria.
