Abstract
Purpose: The aim of this study was evaluation of cephalometric changes in treatment of skeletal class III malocclusion using miniscrews and intermaxillary closing coil springs. Material and methods: Ten patients  with skeletal Class III malocclusion due to maxillary deficiency were selected, their age range from 12 to 15 years old with erupted all permanent teeth. Miniscrews (Hubit, Hubit co, Korea) were inserted (1.6 mm diameter, 10 mm length) in upper arch between upper second premolars and first molars and (1.4 mm diameter, 8 mm length) in lower arch between canines and first premolars were used. A fixed posterior bite plate was used to eliminate occlusal interferences and facilitate bite jumping. The force was immediately delivered (250g) per sides using closed coil spring (Ortho Technology, TAD coil spring, 9mm, USA). Dentoskeletal and soft tissues cephalometric changes were measured by using Orisceph RX3 software (Italy) for pre and after 6th months. Results: Regarding specific cephalometric measurements there was statistically significant difference and soft tissue improvement. Conclusion: Intermaxillary miniscrews supported coil spring is a promising protocol for skeletal class III patient . Success depends on proper presurgical patient counseling and miniscrews placement
