Background:Intrusion of teeth is one of the othodontic movement treatemnt used to treat the alignment. Aim: To assess & evaluate the scientific literature & complie current state of evidence for stability of PTI & AOM by MA. Material & Method: In our meta analysis we have assessed past scientific literature upto 8 in number which were full filling the inclusion criteria for know about atbility of teeth after PTI treatment in 3 different groups i.e. miniscrew , miniplate and both with the help of MPA, FH, OB, UMPP.Result:For MPA-EV, groups 1 & 2 showed positive outcomes that regarding stability on the other hand, group 3, favored relapse rather than stability. For FH-EV, group 1 & 2 showed the steadiness while group 3 showed relapse rather than stability. For OB-EV, groups 1 & 2 had more variation (chi2 =78.59, chi2 = 3.98) and reliable data (I2 = 96% and 75% respectively), but group 3 shown lower variation (chi2 = 1.39) and inconsistent data (I2 = 28%) and UMPP-EV, group 2 & 3 exhibited greater variation (chi2 =2.09, chi2 = 4.75) and conflicting data (I2 = 52% and 79% respectively), whereas group 1 demonstrated less variation (chi2 = 1.76) and consistent data (I2 = 0%) in relation to OB. Conclusion: Relapse does occur but still treatment outcome remains stable even after 1 year of follow-up. Stability can be improved for PTI with proper retention protocol.
