Brief summary
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.
Detailed description
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.
Interventions
DEVICECLEAR ALIGNERS
The CA group included 13 patients treated with clear aligners Tree-dimensional images were captured using a CBCT scan (KaVo® Dental GmbH, Bismarckring, Germany). Te pre-treatment imaging parameters were 120 kV, 5 mA, 0.3 mm voxel size, and a feld of view of 230×170 mm
