ABSTRACT

Ttaking account that sorne authors classify malocclusions as the third oral disease most preva lent, is of great i mportance for orthodontic diagnosis know the mesiodistal width of the teeth for proper relotionship between them onda good post treotment stability. Objedive: Determine ifthere is o difference in the calculation of the Bolton index between different types of malocclusion. Material and methods: lt was formed a sample of 120 models previous study of orthodontic treotment, which wos divided into 3 groups: 40 wiftl malocclusion class 1, 40 with malocclusion class 11, 40 with malocclusion class 111. Mesiodistal widths were measured in both arches first rig ht molar to first left molar. lt was estimated at Bolton index and the information in a Microsoft Excel sheet wos tabulated, making statistics in version 8.1.3StatCalc program. Descriptiva statistics were calculated and ANOVA tests were performed. Results: The 60.83% ofthe sam pie presentad sorne type of denta 1 discrepancy. In maloccl usion class 1 63% had so me kind of discrepa ncy; followed by malocclusion dass 11 wiftl 60% and finally malocclusion class 111 presents 57.14% with sorne type of dental discrepancy. Conclusions: Potients with malocclusion dass 1 are further away than average, in total and anterior relotionship, indicated by Bolton. On the contrary, malocclusion class 111 is the closer to the average described.
