简要总结
Three-dimensional Assessment of Root Resorption following treatment with clear aligners using Cone Beam Computed Tomography Design: A randomized, controlled, crossover, double-blind clinical study including twenty six adult , aged 18-25 years old.
详细描述
Orthodontically induced root resorption is one of the common undesirable sequalae of orthodontic treatment. one third of the patients treated with fixed appliances showed more than 3 mm of root resorption whereas at least 2% of orthodontic patients showed more than 5 mm of root resorption.
There is a controversy in the literature regarding the effect of clear aligners on apical root resorption. One previous study reported that some kinds of removable aligners may have the potential of minimizing orthodontic ally induced root resorption due to the studied piezoelectric property by these materials Till now, the degree of apical root resorption following treatment with (in house) aligners has not been reported in the literature.
