Abstract
Introduction: A chieving acceptable occlusal contact during orthodontic treatment is very important. Tooth size ratios play a major role in the prediction of treatment outcomes. Aim: The aim of this study is to determine the mesiodistal width of missing mandibular central incisor. Materials and Methods: The study sample consisted of study casts of 300 participants in the age range of 18–30 years. Samples having a full complement of teeth with Angle's Class I molar and canine relationships, good intercuspation, normal overjet and overbite, and minimal crowding and spacing. Tooth dimensions were measured using a digital Vernier caliper. The data calculated were used for measuring schedule variance (SV) formula. Results: Based on the achieved data, SV formula is derived. Conclusion: For achieving esthetic profile, it is essential to calculate the correct mesiodistal width of the teeth. Ideal tooth proportions play an important role in achieving good occlusion at the end of orthodontic treatment.
