The effect of combined corticotomy and low level laser therapy on the rate of orthodontic tooth movement: split mouth randomized clinical trial.

Abstract

The aim of this study was to evaluate the combined effect of corticotomy and Low-Level Laser Therapy(LLLT) on the rate of orthodontic tooth movement. Methods: A randomized split-mouth design for 16 female patients compared the rate of maxillary canine retraction using corticotomy combined with LLLT versus corticotomy only. The device used in the present study was an In-Ga-As semiconductor diode laser emitting at 940 nm (IR) with these parameters: 0.5 W/ cm 2 power density, 5 J/cm 2 Fluence, CW, 240 sec time irradiation, weekly for the first month and twice monthly for the next three months. Assessment of the rate of canine retraction was carried out via a series of dental models. Results: A non-significant statistical rate of canine retraction was achieved by LLLT combined to corticotomy compared with the corticotomy technique alone. Conclusion: Low-Level Laser Therapy combined to corticotomy could not achieve a higher rate of canine retraction compared to the golden standard corticotomy technique alone. No long-term adverse effects on the alveolar mucosa were detected following both techniques.

The Effectiveness of Repetition or Multiplicity of Different Surgical and Non-Surgical Procedures Compared to a Single Procedure Application in Accelerating Orthodontic Tooth Movement: A Systematic Review and Meta-Analysis

“…Six completed RCTs [ 16 , 34 - 38 ], with a total of 152 patients, with ages ranging from 15 to 25 years, were included in this SR. One study included only female patients [ 36 ], three studies did not give information about sex distribution [ 16 , 34 , 35 ], while the other two studies included both genders, with a predominance of females [ 37 , 38 ]. Four of the involved studies were of a compound design (COMP) [a parallel-group design with a split-mouth design (SMD) in each group] [ 16 , 34 , 35 , 38 ], and the others were of SMD [ 36 , 37 ]. Three studies touched on the multiplicity of acceleration methods.…”

“…Three studies touched on the multiplicity of acceleration methods. Two of them combined LLLT and surgical interventions (MOPs, corticotomy) [ 34 , 36 ]. In one paper, the authors evaluated LLLT + MOPs versus each of these techniques separately [ 34 ], whereas, in the other study, only the comparison between LLLT + corticotomy versus corticotomy was performed [ 36 ].…”

Moreover, the third study combined multiple osteoperforation with a corticotomy procedure against multiple osteoperforation only [ 16 ].…”

The effectiveness of surgical and non-surgical techniques in orthodontic practice in closing post-extraction spaces: a systematic review

“…Почти во всех рандомизированных клинических испытаниях, вмешательства проводились с вестибулярной стороны альвеолярного отростка, за исключением некоторых статей, где процедура была двусторонней [4,6,7,8]. Для закрытия постэкстракционных пространств в большинстве случаев использовались никель-титановые закрывающие пружины с нагрузкой в 150 [3,4,6,7,8,9,10,11,12,13,14,15] и 250 [16] грамм. Реже для закрытие использовался эластический чейн [4,9,15], tie-back [4] и специальный дистрактор с винтом Hyrex [17].…”

“…Согласно данным Farid et.al. [8] использование лазерной абляции совместно с кортикотомией является не эффективным.…”
