Evaluation of Root Resorption During the Correction of Deep Bite With the Help of Laser Irradiation

As for patients in the control group, the strength of the nickel-titanium coil will be adjusted every 4 weeks to the required strength of 40 g on each end until reaching normal coverage.

"The laser will be applied to the root of each of the upper incisors in 8 points (4 points from the labial and 4 points from the palatine), and the head of the device will be placed from the labial side of the root in the center of each of the apical and middle thirds and the mesial and distal of the cervical third in contact with Oral mucosa perpendicular to the root axis, with the application of the laser beam for (16) seconds at one point, and the laser will be re-applied in the same way from the palatal side of the root. So that it was the total application time is (128) seconds for one tooth.~The laser will be applied on the day the upper incisor intrusion started (T1), then on days (3, 7, and 14) of the first month, and starting from the second month, the laser will be applied every (15) day, in addition to adjusting the force gauge every 4 weeks until the end of intrusion stage (T2) and reaching normal coverage."
