Key words: Accelerated orthodontics, Micro-osteoperforations, Photo-biomodulation, Canine retraction, Premolar extraction Micro-osteoperforation is a more efficient modality of accelerating tooth movement as compared to Photo-biomodulation which can be used in routine orthodontic practice. Micro-osteoperforations (MOPs) significantly increased the rate of maxillary canine retraction by 1.1 fold when compared to the Photo-biomodulation (PBM).The MOPs can successfully reduce the comprehensive fixed orthodontic treatment time by around 9% as compared to PBM.Ĭonclusions. Separate canine retraction was performed and movement was measured over a three month period. In this split mouth study, thirty patients requiring ma- xillary first premolar extraction were randomly allocated for Photo- biomodulation (PBM) on one side and for micro-osteoperforations (MOPs) on other side of maxilla.

The aim was to evaluate the comparative effect of PBM and MOPs on the rate of orthodontic tooth movement (OTM). Photo-biomodulation (PBM) being non-invasive and micro-osteoperforations (MOPs) being minimally invasive. However, there is limited literature, comparing the efficiency of two commonly used modalities which are relatively simple, safe and comfortable chair-side procedures to accelerate orthodontic tooth movement viz. Various modalities have been proposed to accelerate the orthodontic tooth movement (OTM) with varying degree of success. The lengthy duration of comprehensive orthodontic treatment has always been a major concern.
