Overjet as a predictor of sagittal skeletal relationships.
Pak Oral Dental J Jan ;36(3):395-8.

Skeletal relationships in the sagittal plane do not always correspond with dental relationships. The aim of the study was to evaluate the degree of correlation between a dental parameter (overjet) and a skeletal (ANB) angle. Eighty nine patients fulfilled the inclusion criteria for the study ( 22 males and 69 females, aged 12- 35). Overjet was measured on casts with a standard ruler. Lateral cephalograph was taken to measure the ANB angle. The correlation analysis of overjet with ANB angle in the three malocclusion classes showed, that there was a weak correlation of overjet with ANB angle in all three groups of malocclusion with “r” value of 0.257 whereas P value was statistical insignificance (P-value > 0.05). This study concluded that overjet is not a good predictor for sagittal skeletal relationship and therefore could not be used for better assessment of sagittal jaw relation which is critical in orthodontic diagnosis and treatment planning.
