Résumé
The purpose of this article is to introduce a simple appliance that uses a setup model and a nickel-titanium (Ni-Ti) wire for correcting the mesial rotation and drift of the permanent maxillary first molar. The technique involves bonding a Ni-Ti wire to the proper position of the target tooth on a setup model, followed by the fabrication of the transfer cap for indirect bonding and its transfer to the patient's teeth. This appliance causes less discomfort and provides better oral hygiene for the patients than do conventional appliances such as the bracket, pendulum, and distal jet. The treatment time is also shorter with the new appliance than with full-fixed appliances. Moreover, the applicability of the new appliance can be expanded to many cases by using screws or splinting with adjacent teeth to improve anchorage.

Rhabdomyosarcoma originating from the chest wall is a rare malignant tumor in children and was considered to be guarded in prognosis previously. However, recent advances in multidisciplinary treatment of rhabdomyosarcoma in children have improved the disease free survival rate. Authors report a case of alveolar rhabdomyosarcoma, stage III, originating from the chest wall who is surviving free of disease for 15 months with aggressive chemotherapy and radiotherapy.
