Does Gender Have an Effect on Craniofacial Measurements?

Area of Science:

• Orthodontics and Dentofacial Orthopedics
• Craniofacial Biology
• Anthropology

Background:

• Understanding craniofacial morphology variations is crucial for effective orthodontic treatment.
• Gender-specific differences in skeletal and dental patterns can influence treatment outcomes.
• Adolescent growth provides a critical window for evaluating these variations.

Purpose of the Study:

• To investigate craniofacial structure differences based on sagittal malocclusion (Angle Class I, II, III) and gender in adolescents.
• To identify gender-specific variations in skeletal relationships and dimensions.

Main Methods:

• Cross-sectional study of 223 adolescent subjects (102 males, 121 females).
• Evaluation of pre-treatment dental models, lateral cephalometric, and hand-wrist radiographs.
• Analysis of angular and linear measurements using cephalometric data, categorized by Angle Class based on ANB angle.

Main Results:

• Class I males exhibited greater vertical facial dimensions and a protrusive maxilla compared to females.
• Class II males presented with a protrusive maxilla and a larger mandible in position and dimension.
• Class III subjects showed no significant gender differences in maxillary and mandibular sagittal or vertical dimensions.

Conclusions:

• Craniofacial morphology exhibits more gender variation in Class I and II malocclusions than in Class III.
• Orthodontic treatment planning should incorporate gender-specific considerations for optimal results.
• Recognizing these gender differences can enhance the success of orthodontic interventions.
