  • ABSTRACT
  • TITLE
Objective
To establish the normative data of dentofacial transverse dimensions according to the skeletal maturation stage in Korean adolescents with good occlusion.
 
Material and Methods
A total of 577 Korean subjects between ages 7 to 19 years and exhibiting skeletal Class I occlusion were categorized by skeletal maturation index (SMI). Dentofacial transverse dimensions were assessed using posteroanterior cephalograms.
 
Results
Dentofacial transverse norms relevant to skeletal maturation stages were established. Males had greater facial, maxillary and mandibular widths compared to females at every SMI stage. The maxillary and mandibular intermolar widths showed the strongest correlation for both sexes
 
Conclusion
Dentofacial transverse norms of Korean adolescents were established according to developmental stage. All dentofacial widths were greater in males at growth completion. Maxillary and mandibular intermolar widths were strongly correlated.
