Abstract:
A study was made on the effects of cervical headgear on dentofacial structures, especially non-erupted teeth, in the early and late mixed dentition periods. Pretreatment and post-treatment cephalometric evaluation was done on 8 patients in the early mixed dentition period and 10 patients in the late mixed dentition period. The results showed that any reference line passing through Ptm point should not be used to evaluate the efficiency of cervical headgear, and that such headgear is more effective on non-erupted teeth in early mixed dentition.
