Abstract :
Objective The objective of this study was to find the relationship between the arch length required and the depth of the curve of Spee in the leveling of the curve of Spee.
Material and methods The study was performed in dentoform by setting the mandibular teeth in order to increase the depth of curve of Spee from normal to 11 levels which ranged from 1.55 to 6.95 millimetres. The actual arch length in each level was measured and was subtracted from the sum of mesiodistal width of teeth in mandibular arch. The result was the arch length required for each level of the depth of the curve of Spee.
Result The findings indicated that the relationship between the arch length required and the depth of curve of Spee was linear regression which was Y = 0.820 X -1.376.
Conclusion It could be applied in the analysis of study model which was a part of orthodontic diagnosis and treatment planning.
