Objective To summarize the application of uninterrupted force correction appliance for maxillary underdevelopment in children. Methods 16 cases were selected, traction in front of the home was combined with all-day guide bow appliance, and the orthopedic force was maintained for nearly 24 hours. The cephalometric analysis was performed before and after treatment. Results The anterior teeth established normal occlusion, the maxillary hypoplasia improved significantly, and the correction time was significantly shortened. Conclusions The frontal traction and guide bowel appliance are used in combination. The orthopedic force is continuously given throughout the day, which effectively shortens the treatment time.
