This study classified maxillary arch forms in cleft lip and palate patients using CT scans. A simplified U and V-shaped classification with subtypes was developed for pediatric dentistry.

Area of Science:

  • Dentistry
  • Orthodontics
  • Craniofacial Anomalies

Background:

  • Cleft lip and palate (CLP) are common congenital anomalies affecting facial development.
  • Accurate assessment of maxillary arch form is crucial for effective orthodontic treatment planning in CLP patients.
  • Existing classifications may lack simplicity or comprehensive applicability in clinical settings.

Purpose of the Study:

  • To investigate and classify the diverse maxillary arch forms in individuals with cleft lip and palate.
  • To introduce a simplified classification system for maxillary arch forms based on observable patterns.
  • To evaluate the clinical utility of this new classification in pediatric dentistry.

Main Methods:

  • A prospective study involving fifty patients with cleft lip and palate.

  • Maxillary arch form tracing from Computer Tomograph (CT) sections, both pre- and post-operatively.
  • Analysis of traced arch forms to identify distinct patterns and develop a classification system.

    • Main Results:

    • Observed maxillary arch forms were categorized into U-shaped and V-shaped patterns.
    • Subtypes were defined as posteriorly-convergent (c), divergent (d), and parallel (p) for both U and V shapes.
    • The classification demonstrated a clear differentiation of arch forms in the studied cohort.

    Conclusions:

    • A simplified classification system for maxillary arch forms (U and V shapes with subtypes c, d, p) was successfully developed.
    • This classification provides a practical tool for assessing arch morphology in cleft lip and palate patients.
    • The proposed system is suitable for application in pediatric dentistry practice for improved treatment planning.
