The bonding bite plate combined with the face mask protracting maxilla to treat skeletal crossbite in the early mixed dentition

摘要

Objective: To evaluate the orthopedic effects of a new method to treat skeletal crossbite in the early mixed dentition. Methods: Twenty cases (5.8-7.5 years old ) with skeletal crossbite were treated by bonding the bite plate combined with the face mask protracting the upper jaw. Cephalometric radiographs were taken and analyzed before and after treatments. Results: On average, in all 20 cases the maxilla was moved by 2.06 mm forward; the mandible was turned 2.45° downward and backward; the skeletal crossbites were corrected and the facial profiles were improved satisfactorily. The period of treatment was conducted for 1.7 months on average. Conclusion: A good effect can be achieved by bonding bite plate combined with the face mask protracting the upper jaw to treat skeletal crossbite in the early mixed dentition, which will benefit the craniofacial growth and the development of young children.
