Abstract This study was carried out to evaluate the rate of orthodontic tooth movement with the application of micro-osteoperfortion and soft laser therapy during molar Materials and methods Active distalization was started by 240 g at a level of the center of resistance of both maxillary molars. At the Micro-osteoperforation randomized experimental group, local anesthesia was injected. MOPs were placed directly through the buccal mucosa adjacent to the first molar in avertical direction 2 mm apart and 7 mm in depth using an Propel device, width 1.6 mm and length 6. While second group, LASER group was irradiated with low-level GA-Al-As LASER (810 nm, 5 J/cm2). Continuous mode with a frequency of 2 Hz and a power output of 0.2 W of a gallium-aluminum-arsenide semiconductor diode LASER emitting infrared radiation was used. The LASER was applied to the palatal and buccal aspect of molar region for 80 seconds weekly. The LASER application was in accordance with Photon LASER plus unit protocol (DMC, São Carlos, São Paulo, Brazil). Results : Micro-osteoperforations increased maxillary molar distalization along four month distalization period. It seems that distalization was clinically and statistically significant on the experimental side compared to control one. Also Low level laser therapy irradiation (LLLT) significant increase maxillary molar distalization during the four month distalization period. It seems that Laser application was clinically and statistically significant on the experimental side compared to control one. Conclusions : Positive effectiveness of micro-osteoperforations and Laser on the rate of orthodontic tooth movement during maxillary molar distalization. |
