Abstract :

This study was undertaken to evaluate and compare the anchorage value of mini-implants against a unit of II premolar, I and II molar as anchor unit. 20 cases were treated with PEA appliance, wherein anchorage planning for 10 cases was using mini implants and for 10 cases using a consolidated unit of II pre molar, I and II molar, reinforced with Transpalatal Arch at I molar. Orthodontic study models were used in both the groups to observe pre and post anterior retraction changes. Post-treatment changes within and between groups were analyzed by Independent sample t test and Paired sample t test. The implant supported cases show negligible mesial molar movement as compare to consolidated unit of II pre molar, I and II molar cases. The results have been tabulated and discussed. It was concluded that, although implants are the absolute anchorage devices, ancorage loss in the unit of consolidated II pre-molar, I and II molar was not statistically significant.
