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

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.
