Longitudinal changes in Class I subjects with moderate mandibular skeletal protrusion

A T Karlsen

    The Angle Orthodontist
    |October 14, 1998
    PubMed
    Summary

    Craniofacial morphology differences in Class I females were present by age 6. Mandibular protrusion, not jaw size, distinguished groups, with growth maintaining these initial jaw-base relationship differences.

    Area of Science:

    • Orthodontics
    • Craniofacial Morphology
    • Pediatric Growth Studies

    Background:

    • Class I malocclusion is common.
    • Jaw base relationships influence facial aesthetics and function.
    • Understanding early developmental patterns is crucial for orthodontic intervention.

    Purpose of the Study:

    • To compare craniofacial morphology and growth between Class I females with normal and mesial jaw-base relationships.
    • To identify the specific morphological traits contributing to differences in jaw-base relationships.
    • To determine if observed differences are established early and maintained throughout growth.

    Main Methods:

    • Longitudinal study of two groups of Class I females (n=unknown).
    • Evaluated subjects from 6 to 18 years of age.
    • Compared craniofacial morphology, focusing on jaw-base relationships and jaw size.

    Main Results:

    • Subjects with mesial jaw-base relationships exhibited mandibular skeletal protrusion.
    • This protrusion resulted from a more forward mandibular position relative to the anterior cranial base.
    • Morphological differences were present at age 6 and persisted, though some became less distinct by age 18. Jaw size did not differ between groups.
    • Incremental jaw growth was comparable between groups, suggesting growth patterns helped maintain initial differences.

    Conclusions:

    • Early-established mandibular positioning is a key factor in mesial jaw-base relationships in Class I females.
    • Jaw size is not a differentiating factor in this cohort.
    • Similar jaw growth rates contribute to the persistence of initial craniofacial morphological variations.
