Abstract

Background: Intrusion of maxillary incisors with anterior mini-implants has been reported to produce absolute intrusion with minimum proclination of incisors. There are very limited scientific evidences about the efficacy of intrusion mechanics with one versus two mini-implant assisted intrusion.
The primary and secondary objectives of this trial was to investigate the effect of one verses two mini-implants on the amount of incisor intrusion and changes in the axial inclinations of maxillary incisors.
Single centre,Parallel arm, Prospective Randomized Controlled Clinical Trial
Materials and Methods: Sixty, male and female subjects (20-30 years of age) requiring correction of deep bite or gummy smile was divided equally into Group 1 & 2. One mini- implant was placed between maxillary central incisors in group-1 & two mini- implant were placed between maxillary lateral and canine bilaterally in group-2. Incisor intrusion and axial inclination were measured from lateral cephalograms before and 4 months after intrusion. A force of 80 gm was applied from min-implant to arch wire with elastomeric chain in both the groups. Data was analysed by independent‘t’ test.
Results: The mean amount of incisor intrusion was significantly greater (p<0> Conclusion: Both the methods for maxillary incisor intrusion were effective but two mini-implants assisted intrusion can be preferred as this method produce more amount of incisor intrusion with minimum proclination of maxillary incisors.
