简要总结
Erbium lasers have been suggested to accomplish corticotomy without flap reflection due to their attractive advantages. The current trial aimed to evaluate the efficacy of laser-assisted flapless corticotomy in accelerating orthodontic tooth movement. The secondary aim was to evaluate the patients' responses to laser application. It was postulated that canine retraction after laser-assisted flapless corticotomy would be accomplished within a shorter period compared with the conventional canine retraction method, with no significant degree of pain and discomfort.
详细描述
Comprehensive orthodontic treatment with fixed appliances usually takes more than 18 months in mild and severe cases. Prolonged treatment time can cause many adverse effects such as pain, discomfort, external root resorption, white spots and dental caries. Decreasing the treatment time for tooth movement has been the focus of both the clinicians and the patients. For the last few decades, investigators have recommended many treatment approaches intending to reduce overall treatment time such as low friction and self-ligating bracket systems, low-level laser irradiation, electrical currents, pharmacological approaches, local platelet-rich plasma (PRP) injection and surgical approaches like dentoalveolar distraction and selective alveolar decortication or corticotomy

结局指标
主要结局
Change in the canine retraction rate
时间窗: 10 minutes after laser application, one, two, four, 8 and 12 weeks after laser application
The distance between the first molar labial hook and the canine bracket hook was recorded using Digital Boely gauge and then this distance was divided by the time that passed between two assessment points.
次要结局
- Change in the levels of pain and discomfort(at the 1st day following laser application (10 minutes) and at the 3rd, 5th and 7th days following laser application)
