Research is randomized, not blinded, without using placebo. Inclusion criteria are patients without extraction and with moderate crowding (5-9 mm), rotated teeth less than 30 degrees. Group 1: who are treating with a diode laser to alleviate relaps. The laser emit a wavelength of 810 nm and operate in continuous wave mode with maximum power of 200 mW from the mesial maxillary canine of one side to the opposite side. The laser probe will be position in contact with gingival tissue in the coronal third of the root, and the irradiation will perform on 4 points around the tooth, including mesiobuccal, distobuccal, mesiolingual, and distolingual areas. The laser irradiates for 50 seconds per point, and thus each tooth receive 200 seconds of laser irradiation. Laser will irradiate 2 times before removing arch wire (7days and immediately before removing arch wire). Immediately after bracket debonding, Dental impression will be taken. After 4 months of using fulltime retainer, impression will be taken. The patients are asked to use retainer about 8 hour per day for one month. The fourth impression will be taken after 6 months after removing arch wire. The second group will not be undergoing any laser radiation. Crowding will measure.
