ABSTRACT

The aim of this study was to examine cephalometrically the dental and skeletal effects of mandibular headgear in pseudo-prognathia cases. For this purpose, pretreatment and posttreatment lateral cephalograms of 40 early mixed dentition Class III subjects were evaluated (13 girls and 7 boys used mandibular headgear and 10 girls and 10 boys formed the control group). The total observation period was one year. Results showed that the general growth and development of the mandible were inhibited, lower anterior face height was increased and the lower molars moved significantly distally.
