Dento-skeletal changes in patients using twin-block appliance- A pre and post treatment comparison

AUTHOR(S): Sneh Kalgotra, Dr. Mohammad Mushtaq, Dr. Mariya Qadir
ABSTRACT:Background: Class II patients show specific clinical characteristics, such as a large overjet resulting in a soft tissue profile imbalance. This is closely related to patients' and parents' complaints concerning self-image and self-confidence. In order to reestablish their self-esteem, an early approach into correction of the dentoskeletal disharmony and improvement of facial esthetics may be indicated in the pre-pubertal stage, sometimes leading to two-phase orthodontic treatment. Aim of study: To evaluate dentoskeletal changes in patients using twin-blockappliance. Materials and method: The study was conducted in the post- graduate department of Orthodontics and Dentofacial Orthopedics of the Dental institute. 32 patients were selected from patients attending the out patient department of orthodontics. Cephalometric radiographs of the patients were obtained at the beginning of the study (T1) and after completion of the treatment (T2) (treatment time 1 year ±3.6 months). The changes in the dento-skeletal parameters were studied by comparing T1 cephalogram and T2 cephalogram. Results: In case of skeletal changes we observed significant increase in the spatial position of the mandible related to the anterior cranial base (SND) and significant reduction in the measurements related to maxillomandibular sagittal position. In case of dental parameters, we observed statistical changes on upper incisors position (1/NA degree) and on lower incisors tipping (1/NB degree), which resulted in significant increase of interincisal angle. Conclusion: From the results of present study we conclude that there is a significant improvement in the total mandibular length and anteroposterior relationship in patients treated with twin-block appliance.
