Effect of micro-osteoperforations on rate of space closure by mini-implant supported maxillary anterior en-masse retraction: A randomized clinical trial

Effect of the minimally invasive micro-osteoperforations (MOPs) on the orthodontic tooth movement A prospective, randomized clinical trial

“…Since Alikhani et al published their studies in 2013, evaluation of the effects of MOPs on orthodontic tooth movement in humans has not been done frequently, but the vast majority of papers have focused on Class II/1 disorders treated with extractions of the first premolars, as in our study (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). This is understandable, since patients with class II/1 malocclusion rarely demonstrate occlusal interferences, which prevents masticatory forces from influencing the rate of tooth movement.…”

“…In turn, Alikhani et (17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). Jest to zrozumiałe, bowiem u pacjentów z wadą dotylną II/1 rzadko występują przeszkody zgryzowe, co zapobiega wpływaniu sił żucia na szybkość ruchu zębów.…”

“…W większości cytowanych badań ruch zębów oceniano na podstawie zakresu retrakcji kłów tradycyjną metodą zamykania przestrzeni poekstrakcyjnej (18)(19)(20)(21)(22)(23)(24). Jednak w erze TISAD można zmierzyć wpływ MOPs na retrakcję en masse sześciu zębów przednich, co było przedmiotem nielicznych badań (25,30). Attri i wsp.…”

“…In majority of the quoted studies the tooth movement was evaluated basing on the canine retraction range in the conventional mode of an extraction space closure (18)(19)(20)(21)(22)(23)(24). However, in the TISAD era it was possible to measure the effect of MOPs on en-masse retraction of six anterior teeth, which has been done in a few studies (25,30). Attri et al evaluated 60 patients whose orthodontic treatment plan called for extraction of four first premolars (25).…”

“…Thus, tooth movement accelerated by RAP may have been blocked by presumably slower tooth movement in the maxillary quadrant without MOPs. On the other hand, Attri et (25,30). Niemniej, pomimo retrakcji en masse, przeprowadzonych zarówno w obu tych badaniach, jak i w naszym, odmienna metodologia pomiarów uniemożliwia porównanie bezpośrednie.…”
