Alt keser çapraşıklığı olgularında şeffaf plaklarla yapılan ortodontik tedavilerde ışık ve titreşimin tedavi süresi üzerine etkisi

The aim of this study is to evaluate the effects of lights and vibration on aligner treatment duration cases with lower crowding of mandibular incisors. There are invasive and non-invasive methods for accelerating orthodontic tooth movement. There is a tendency for both clinicians and researchers to focus on accelerating methods for orthodontic tooth movement due to the huge demand for adults for a shorter orthodontic treatment time such as medicines, led light force, low level of laser theraphy, photo biomodulation, surgical methods, corticotomy, piezocisions, decortication or micro-osteoperforation, combination of led light and vibration, bracket systems or digital methods. With this study it was also desired to create a more conservative technique to accelerate tooth movement than those other methods, which would easily be accepted by the patients and have continuous effects throughout the desired period of the treatment.In this retrospective study, a total of 89 patients who applied to Yeditepe University Faculty of Dentistry Department of Orthodontics were included in the study. Patients were assigned to four groups. First group which included 19 (11 female, 8 male) patients was the control group. Second group with 26 (14 female, 12 male) patients received a 30 Hz 25 N vibration device, third group which had 21(12 female, 9 male) patients received a device which produced 850 nm LED light and the last group consisting of 23 (14 female,9 male) patients got a device which combined vibration and light features. All patients with devices were asked to use them 20 minutes daily. At the initial appointment (T0), at 28 days later (T1), at 48 days later (T2), and 62 days later(T3) impressions were taken to produce dental casts. The tooth movements of the patients were recorded measuring the differences in amounts of crowding. According to measuring on 62 nd day; there is no statistical differences between control group and neither photo biomodulation group nor vibration group. A significant increase in speed of tooth movement speed was observed in the HOT group (p<0.05). The treatment done with clear aligners and the combination of light and vibration might be an effective method in accelerated orthodontic tooth movements.
