フォトバイオモジュレーションは歯列矯正のアライメントを加速する – 要旨

背景: 歯列矯正治療において患者に必要となる治療時間を短縮すべく、数多くの戦略が提案されてきた。 近年では、装置による加速治療がいくつか登場している。フォトバイオモジュレーションは、 人間の生物学的プロセスに臨床応用されている新たな科学分野である。 本研究の目的は、フォトバイオモジュレーションが歯列矯正治療のアライメントフェーズにおいて、治療時間を短縮するか否かを明らかにすることである。

Methods: This multicenter clinical trial was performed on 90 subjects (73 test subjects and 17 controls), and Little’s Index of Irregularity (LII) was used as a measure of the rate of change of tooth movement. Subjects requiring orthodontic treatment were recruited into the study, and the LII was measured at regular time intervals. Test subjects used a device which produced near-infrared light with a continuous 850-nm wavelength. The surface of the cheek was irradiated with a power density of 60 mW/cm2 for 20 or 30 min/day or 60 min/week to achieve total energy densities of 72, 108, or 216 J/cm2, respectively. All subjects were fitted with traditional orthodontic brackets and wires. The wire sequences for each site were standardized to an initial round alignment wire (014 NiTi or 016 NiTi) and then advanced through a progression of stiffer arch wires unit alignment occurred (LII < 1 mm).

Results: The mean LII scores at the start of the clinical trial for the test and control groups were 6.35 and 5.04 mm, respectively. Multi-level mixed effect regression analysis was performed on the data, and the mean rate of change in LII was 0.49 and 1.12 mm/week for the control and test groups, respectively.

Conclusions: Photobiomodulation produced clinically significant changes in the rates of tooth movement as compared to the control group during the alignment phase of orthodontic treatment.
