Relationship between mandibular arch shape and skeletal jaw base in various growth patterns among north Maharashtrian population

TL;DR

This study examines how mandibular arch shape relates to skeletal jaw base in different growth patterns among North Maharashtrian individuals.

Contribution

The study provides new insights into the lack of correlation between mandibular arch shape and skeletal jaw base classifications.

Findings

Growth patterns show statistically significant associations with skeletal variables like OP-MP angle and Jaraback ratio.

Mandibular arch width does not consistently correlate with skeletal classifications I, II, or III.

Individualized orthodontic assessments are emphasized due to variable relationships observed.

Abstract

Achieving stable orthodontic results requires an understanding of the relationship between the skeletal jaw base and the shape of the
mandibular arch across different growth patterns. Therefore, it is of interest to analyse 63 North Maharashtrian subjects grouped by
horizontal, average and vertical growth patterns and skeletal classifications I, II and III using cephalometric parameters (SN-MP, ANB
and Wits index). Cephalometric and dental cast measurements were recorded and statistically analyzed using SPSS version 24. Statistically
significant associations were found between growth patterns and several skeletal variables such as OP-MP angle and Jaraback ratio but,
skeletal classifications showed no consistent correlation with mandibular arch width. Thus, we show that while certain skeletal
parameters vary with growth patterns, mandibular arch shape does not reliably correlate with skeletal jaw base classification,
highlighting the need for individualized orthodontic assessment.
