Aims:
Extended orthodontic treatment leads to a number of negative outcomes, including a higher chance of dental cavities, gingival recession, open gingival embrasure gaps, and root resorption. It has been stated that micro osteoperforations (MOPs) use the biology of the body to speed up tooth movement. Our objective was to investigate how MOPs with micro implants affected the tooth movement rate.
Methods:
A parallel arm clinical trial at Noorul Islam College of Dental Sciences involved 36 maxillary quadrants from 18 patients aged 14-20 with class I malocclusion requiring maxillary first premolar extraction. The left quadrant served as a control, and the right as the experimental side. Following alignment with the MBT bracket system, MOPs with mini implants were conducted on the experimental side before retraction. This process was repeated every 28 days for three months. Tooth movement on both sides was measured and analyzed using SPSS 26.0.
Result:
The rate of retraction did not differ statistically significantly between the experimental and control groups. In the experimental group, the mean rate of retraction was 5.77 ± 0.71 mm, while in the control group, it was 5.71 ± 0.73 mm.
Conclusion:
Micro osteoperforations (MOPs) used in the study didn't facilitate an enhanced retraction rate.
