Interbracket distance differences between different lingual systems
Vol 36, Issue 2S4, 2022
Abstract
OBJECTIVE: The aim of the study was to analyze and compare the interbracket distance in crowdedarches of different lingual appliances.MATERIALS AND METHODS: The stereolithographic models of the same patient with 4 differentlingual appliances were used to analyze the interbracket distance. 3Shape software was used to analyzethe interbracket distance for each arch segment and by means of a mathematical formula the forceexpressed by the different appliances in the different arches segments was calculated.RESULTS: Incognito, eBrace and Harmony reported an average interbracket distance of less than 6mm, while STb system showed an average values of 7 mm.CONCLUSION: The interbracket distance, which have an influence on the system stiffness androtational control of the teeth, is significantly greater in STb appliances compared to eBrace, Incognitoand Harmony appliances.
